5v5 DEFENSIVE LAB

What this app does: It combines a 5v5 flag-football play diagram, player movement animation, defensive assignments, teaching pauses, video study, and exports.

Understand the workspace

1. The field is your drawing and teaching surface. Tap or drag players and use the active tool to change what your touch does.
2. The play controls above/below the field handle animation, drawing, editing, scene switching, and formations.
3. The collapsible panels—Edit Plays, Play Library, Teaching Lab, Scene Manager, Export Videos & Photos, Team Branding—contain advanced controls.
4. Scene 1 establishes the pre-snap picture. Scene 2 handles the post-snap action. Additional scenes can extend the teaching sequence.

Tip: Start with the simplest two-scene play before adding disguise steps, film, or teaching pauses.

Main buttons

• MOVE: reposition a player on the field.
• DRAW: draw an offensive route or defender movement. Finish the path when done.
• ZONE: assign or draw a defender's zone/bubble.
• EDIT PATH: adjust existing route or movement waypoints.
• BLITZ: create a defender's blitz path.
• ERASE: remove the selected drawing/element using the erase tool.
• PLAY SCENE: animate the play. UNDO / REDO: step backward or forward through recent edits. FINISH PATH: complete the current multi-point drawing.
• FULL PLAY PREVIEW: review the full play sequence.

Coverage — Rules

Use the action selector to choose the assignment type, then tap the required defenders and receivers in the order shown by the selected action. The chosen tool/action determines whether a tap draws, selects, or assigns.

Edit Player dropdown

Use CLEAR SELECTION to deselect. With a player selected, the menu includes Erase selected route / movement, Erase selected zone bubble, Erase selected man / match assignments, Erase BRACKET / READ / TRIO, and Clear selected player edits. These remove the relevant edits rather than deleting the player from the field.

If a tap does the wrong thing, check the active tool and coverage action first.

Every scene is editable

Move offense or defense, draw motion/routes, and edit assignments in any scene. When positioning offensive players in PRE-SNAP or SNAP STARTER alignment, SELECT stops at the yellow line of scrimmage. Lateral and backfield positioning remain free; drawn routes can cross the line. New routes start at the current scene position. Scene Manager provides duplicate, reorder, scene duration, and SET SNAP STARTER.

SNAP STARTER

Designate the first snap-execution scene. All earlier scenes are PRE-SNAP; all later scenes are POST-SNAP. The designation follows its scene when reordered. Add as many pre-snap motion and defensive-adjustment scenes as needed. Snap-based blitzes wait for SNAP STARTER.

Motion first, routes together at the snap

Use PRE-SNAP MOTION for movement before the snap. Ordinary receiver routes drawn in a pre-snap scene now wait for SNAP STARTER, even after a receiver has moved. In Player Controls, RECEIVER PATH START selects AT SNAP — ROUTE or IN THIS SCENE — MOTION / CONTINUATION. Select an existing receiver and choose AT SNAP to correct an early-running route without redrawing it. Pending routes survive scene duplication and paused snapshots; routes start together at the snap from their current positions.

Names and snapshots

Automatic names follow the scene role. Renaming a scene makes the name manual. Duplicate copies the complete scene; DUPLICATE PAUSED FRAME captures every player at the actual paused moment and retains the remaining execution independently.

Playback

PLAY animates the selected scene. FULL PLAY PREVIEW runs every scene in order. Film Room scrubbing uses the same positions and timing as JPEG/video exports.

Draw a route or movement path

1. Switch to any scene you want to edit.
2. Choose DRAW and select the player.
3. Drag from the player to aim one straight segment, then release to set its endpoint. Tap or drag again to add the next waypoint. Finger wobble does not add bends. Use SHARP / SQUARE or rounded breaks to shape deliberate corners.
4. Tap DONE. Use ADJUST to move existing waypoints if necessary.
5. Tap PLAY SCENE to confirm the player follows the intended bends.

Offensive routes are shown in green with arrowheads; defender movement paths use a white/gray dashed style. The actual appearance can also depend on the chosen tool and assignment display settings.

Line Pattern

Use the LINE PATTERN dropdown to select STRAIGHT, DOTTED, or SQUIGGLY (AUTOMATIC). Dotted is a dotted visual line; squiggly is a display style, not a command to make the player zigzag.

Route Breaks

Use the ROUTE BREAKS selector (including SHARP / SQUARE) to change how route turns appear. Draw at least two segments when you need a visible route break. Rounded breaks use the same curve for drawing and actual movement. Add or delete individual waypoints in Player Controls.

Other nearby controls

RESTORE DEFAULT DEFENSE returns the default defensive alignment. PRE-SNAP MOTION adds a motion scene; neither is a route-pattern selector.

Choose the coverage/action, then select players in the sequence required by that action. Use Scene 2 for post-snap defensive responsibilities.

Man and Match

1. Select the MAN or MATCH assignment action.
2. Tap the defender, then the offensive receiver.
3. Repeat for other defenders. Review with PLAY SCENE.

MAN is shown with a yellow assignment line and tracks the receiver. MATCH is shown with a white line; the defender can work from a zone before matching the receiver.

Zone

Choose ZONE, select a defender, and drag toward the intended zone. A white line terminates in a bubble. Zone visibility and opacity are configurable in Edit Plays.

Bracket

For the bracket action, select two defenders, then the receiver. The app's bracket teaching logic uses the nearer defender on the release and the other as the quarterback blitzer. Review the animation to confirm the correct personnel and path.

Read — High / Low

1. Select the READ action.
2. Tap the LOW defender, then the HIGH defender.
3. Tap the slot receiver, then the outside receiver.
4. Review the read response in playback. If the slot releases outward, LOW takes slot and HIGH takes outside; otherwise HIGH takes slot and LOW takes outside. Neither is a blitzer in this READ action.

The order of player selection matters for READ. If HIGH and LOW appear reversed, clear the READ assignment and reassign in the listed order.

TRIO — defender triangle

Select TRIO and tap three different defenders. Yellow dotted lines connect their current positions, with “TRIO” centered inside. No receiver is selected or automatically assigned. Draw any separation or movement yourself, then separately assign MATCH to the appropriate defenders and receivers. The annotation stays independent of those assignments and appears in annotated JPEG/video exports. Use Erase BRACKET / READ / TRIO on a selected member to remove the triangle.

Other teaching actions

The Teaching Lab also includes MEG, MATCH, DISGUISE, TRIO, TROCA, and AJUDA teaching moments. Their detailed assignment behavior depends on the selected coverage and play setup; verify the player relationships in the animation rather than assuming all actions use the same selection order.

Zone drop → paused frame → MATCH

ZONE retains its moving defender/drop behavior. Pause when the defender reaches the zone, then use DUPLICATE PAUSED FRAME. The completed zone line and bubble remain an annotation. In Player Controls, select MATCH ACTIVATION → AT THIS SCENE START — COACH HANDOFF, then assign MATCH to the defender and receiver. The short glow ends after about 1.25 simulation seconds; coverage tracking continues. The default MATCH option still waits for a push beyond seven yards.

Open EDIT PLAYS → ⚡ BLITZ SETTINGS to find Blitz Origin, Blitz Actions, Blitz Delay, Blitz Speed, Bracket Blitz Speed, and Second Bracket Blitz Pause Duration together.

Draw a blitz

1. Open Scene 2, choose BLITZ, and select the defender who will rush.
2. Draw the lateral or direct rush path, adding waypoints as needed.
3. Tap FINISH PATH and use PLAY SCENE to check the rush.

Blitz paths are drawn in red. If the red arrow is set to fade at the snap, the player's rush still continues during playback.

Blitz settings in Edit Plays

BLITZ ORIGIN · UNDERNEATH ZONE controls the rusher's origin/alignment choice. SELECT BLITZ ACTIONS contains the available blitz calls: BRACKET, TRAP FIRE, FREEZE, TRAP SILENT, DELAY, RÁPIDA, and SEM BLITZ. The BLITZ DELAY selector provides None, 0.5, 1, 1.5, and 2 seconds.

Disguise sequence

1. In Edit Plays, choose the desired Disguise and Tagged Receiver.
2. Tap + Add step to record that stage.
3. Change the disguise or coverage and add another step for the next transition.
4. Use Clear steps to remove the disguise sequence.

Blitz delay and BLITZ SPEED are separate controls: one changes when the rush begins; the other changes how quickly the drawn path is traveled.

FREEZE receiver tag, Buzz, and Sink

Select FREEZE in Blitz Actions, then choose FREEZE BLITZ — TAGGED RECEIVER. The receiver identifier appears on the field, in coaching notes, the automatic play name, and exports. Tagging alone does not invent a receiver delay or movement: use your drawn paths, scenes, and blitz-delay settings. Buzz and Sink are available in the existing Disguise selector in Play Setup. BUZZ, BAIL, CARRY, FECHAR, FREEZE, SOME, SINK, RODAR, NUVEM, and SHOWTIME identify coaching techniques only. Selecting them never moves defenders, selects a destination, or starts a blitz. Duplicate a scene, draw or position the defender at the desired destination, then duplicate again and separately assign MATCH to the explicit receiver. Ordinary duplication carries final positions forward and retains completed arrows as annotations. BASE is aggressive MATCH-first; Cover 2 Strong/Weak, Diamante, U, and Chuva are zone-first → MATCH. Those descriptions never override the manually constructed scenes.

1. Open the full-width FORMATIONS & ALIGNMENTS dropdown below the drawing controls.
2. Choose the desired preset or adjust players manually on the field.
3. Use SET STARTING ALIGNMENT to establish the current player locations as the pre-snap starting positions.
4. Use RESET POSITIONS when you want to reset the field positions.

Save your own alignment

Use SAVE ALIGNMENT to store a custom formation; DELETE SAVED removes a saved alignment. EXPORT LIBRARY and IMPORT LIBRARY back up or restore your alignment presets.

Formation choices in Edit Plays

Offensive Formation and Strength (Strong Left / Strong Right) set the offensive structure. Choose coverage and disguise separately. RESTORE DEFAULT DEFENSE restores the default defense rather than loading a saved custom preset.

EDIT PLAYS contains the play's tactical and display settings, not just drawing tools.

All blitz controls are grouped inside the expandable ⚡ BLITZ SETTINGS section, including the bracket-specific pause duration and both rush speed controls.

• Offensive Formation / Strength: choose the offensive structure and strong side.
• Coverage / Disguise: choose the defensive presentation and pre-snap look.
• Blitz Origin / Select Blitz Actions / Blitz Delay: set the rush setup and call.
• Tagged Receiver: select the offensive player referenced by the selected teaching/disguise action.
• Disguise / coverage sequence: add or clear sequential teaching steps.
• Field View: switch between the full 70-yard field and a zoomed coaching window.
• Ball Spot: choose the yard-line location in 5-yard increments.
• NO FLY ZONE overlay: show/hide zones and adjust opacity from 0% (invisible) to 100% (fully visible). This includes the RAIL areas; near the opponent's goal line the zones compress to fit the remaining field.
• Assignment Display: show pre-snap only (fade at snap), follow players throughout, or hide.
• Red Blitz Arrow During Playback: fade at snap, keep visible, or hide.
• Player Marker Size: Normal, Large, or Extra Large to make players easier to select and move.
• Route Line Thickness: Small, Normal (original thickness), or Large. Adjusts the drawn offensive and defensive route/movement line width without changing paths or timing.

Review the animation

1. Tap PLAY SCENE to animate the current play.
2. Use the timeline/scrubber where available to move backward or forward to a specific moment.
3. Use the play/pause and restart controls in the preview or Film Room to repeat a teaching point.
4. Choose FULL PLAY PREVIEW for a full-sequence review.

🎬 Coaches Film Room

Open 🎬 COACHES FILM ROOM for a cleaner, larger field view while teaching or screen sharing. The Film Room is separate from the full editing interface and is intended to keep playback and scrubbing controls available. Choose EXIT FILM ROOM to return to editing.

On iPad or Safari, fullscreen behavior and recording formats depend on browser support. If a browser blocks fullscreen, use the expanded in-page view and the visible timeline controls.

Choose a teaching playback mode

• Automatic · hold key moments: playback pauses at teaching points for the chosen duration.
• Manual · Next to advance: pause at teaching points until you press NEXT ▶.
• Continuous · no pauses: play without teaching holds.

Hold each moment offers 1, 2, 3, 5, 7, or 10 seconds. The separate SECOND BRACKET BLITZ pause duration is now in Edit Plays → BLITZ SETTINGS.

Teaching labels

The teaching row includes BRACKET, READ, MEG, MATCH, DISGUISE, TRIO, TROCA, and AJUDA. These provide teaching moments tied to the selected coverage or disguise sequence.

Save teaching images

Save Pause JPEG saves the current teaching frame. Export All Pause JPEGs exports the teaching pause images. For video export, the app uses timed holds rather than waiting indefinitely for a manual NEXT press.

For an uninterrupted demonstration, choose Continuous. For a live class, Manual mode lets you control when the next explanation appears.

Manage the scene sequence

+ Scene adds a scene; Duplicate copies one; Delete removes the selected scene. Tap a scene in the Scenes row to make it active before editing scene-specific settings.

Annotate the scene

FIELD SCENE ANNOTATION includes a Portuguese main label and English subtitle. These appear on the field and are included in JPEG and video exports. Scene title names the scene; COACHING NOTES · THIS SCENE stores explanations with that scene.

Adjust animation timing

• Scene duration (sec): how long the scene lasts.
• Defender drop / pursuit speed: movement speed for Man, Match, and coverage pursuit.
• Defender Match Speed: how quickly defenders close on receivers after the initial drop.
• All Receivers Speed: adjusts X, C, SL, and Z together without changing their drawn routes.
• Playback Speed: 0.5×, 1×, or 1.5× playback.

Change one speed setting at a time, replay, and compare. A delay changes the start time; a speed setting changes the travel rate.

1. Open TEAM BRANDING.
2. Enter TEAM NAME, END-ZONE TEXT, and TEAM TAGLINE.
3. Upload a TEAM LOGO in PNG, JPEG, or WEBP format if desired.
4. Choose PRIMARY ACCENT, SECONDARY ACCENT, BACKGROUND, and PANEL COLOR.
5. Tap SAVE TEAM PROFILE.

NEW PROFILE creates another team identity. RESTORE BRASIL THEME restores the original Brasil theme. DELETE PROFILE removes the selected team profile.

Team theme colors change the interface/branding; the coverage assignment colors remain unchanged so their meaning stays consistent.

The wrong player moves or receives an assignment

Check whether SELECT, DRAW, BLITZ, ZONE, ADJUST, or ERASE is active. Clear the selection if needed, choose the correct action, and select players in the required order.

A route doesn't follow the intended corner or break

Make sure you placed the route's bend/waypoints and pressed FINISH PATH. Use ADJUST to reposition points. LINE PATTERN affects visual appearance, not the player's route geometry.

A READ defender is marked HIGH/LOW incorrectly

Clear the selected READ/bracket assignment, then assign LOW defender, HIGH defender, slot receiver, outside receiver in that order.

A blitz arrow disappears but the player still rushes

Check Red Blitz Arrow During Playback in Edit Plays. A fading annotation does not cancel the actual blitz movement.

Teaching pauses interrupt the animation

In Teaching Lab, switch to Continuous · no pauses, or use Manual and NEXT ▶ when you want to advance.

A video won't import or fullscreen won't open

Try a browser-supported MP4 and verify browser permissions/support. Film Room's fullscreen behavior can differ between Safari and desktop browsers.

A saved play is missing on another device

The Play Library does not sync between devices. Export the play as JSON from the original browser, import it on the new device, then save it there.

Fast navigation

Build: Scenes → MOVE/DRAW/BLITZ → Finish Path → Coverage. Teach: Teaching Lab → Playback mode → Teaching pauses → Film. Share: Play Library → Save → Export JPEG or Video.

Quick-access toolbox

The TOOLS button beside the field lock and Coaches Film Room opens shortcuts to commonly used sections. It does not replace the full editors.

1. Choose a player from the EDIT PLAYER selector or select a player while the field is unlocked.
2. Open TOOLS → CUSTOMIZE SELECTED PLAYER. The customization section opens with that player selected.
3. Change the display label (up to three characters), marker shape (circle, triangle, or star), solid/outline fill, marker color, and opacity.
4. Tap APPLY TO PLAYER. The appearance updates on the field and is saved locally on this device.
5. Use RESET PLAYER to restore that player's standard appearance. Use TEAM BRANDING for the existing team color and logo controls.

Important: Changing a display label does not rename the player's internal ID or change their assignment. The lock protects the drawing surface; opening the toolbox does not unlock it. Player appearance and supported settings are included in portable play JSON and complete backups. Importing a play preserves its scene and customization metadata.

Plays and animation scenes

A play is the complete defensive design. Animation scenes are the stages within that play, such as pre-snap alignment, motion, and post-snap reactions. Use SCENE MANAGER to manage those stages; the toolbox provides a shortcut.
