1) First launch & permissions

On first open, the app asks for the minimum required permissions:

Draw over other apps (for floating hub/overlays).

Record audio (if you choose Microphone/Internal/Auto).

Camera (only if you enable Facecam).

Android shows the screen-capture consent popup the first time you start recording.

Your choices (theme, language, last settings) are saved and restored next time.

2) Home screen

Top-left: the app logo (replacing the text title).

Center: Start Recording button and a “Countdown: N seconds” label that live-updates when you change the value in Settings.

If Facecam is ON, a draggable facecam preview appears on the screen (circle/rectangle/square).

Bottom navigation (left→right): Video • Home • Facecam • Brush • Gallery.

3) Bottom navigation actions

Video: opens the recording section (same Start button, quick status).

Home: returns to the main page.

Facecam: toggles Facecam ON/OFF immediately (stays in sync with the Settings switch).

Brush: shows the floating brush hub (overlay toolbox). Tap again to hide.

Gallery: opens the in-app gallery of all your recordings.

5) Starting a recording

Tap Start Recording:

A center-screen countdown runs from your Settings value (e.g., 5 → 1).

After countdown, recording starts.

The floating recording hub (bubble) appears with time and controls.

If “Hide Brush Bubble During Recording” is ON, the brush hub/toolbar auto-hides when recording starts.

6) Floating recording hub (while recording)

Tap to expand the radial controls (styled like your spec):

Pause / Resume, Stop, Home, and the elapsed time.

Optional Show touches toggle if enabled.

Auto-hide after a few seconds of inactivity (tap again to show).

A notification also shows Pause/Resume/Stop; actions work from the shade.

Hub becomes lighter/semi-transparent when collapsed/hidden.

7) Recording settings (More • top right of Home)

Audio: Microphone, Internal audio, Mute, and (optionally) Auto (Internal + Mic).

Video: Resolution = SCREEN / 1080p / 720p (no pixel text), FPS, Bitrate (slider up to 20 Mbps, CBR-style targeting).

Orientation, Countdown seconds, Floating icon ON/OFF.

Language (changes UI immediately).

Theme (Light/Dark).

Save location (MediaStore folders so files appear instantly in system Gallery).

All changes apply live; you don’t need to toggle features OFF/ON to see effects.

8) Brush / Markup overlay

Tap Brush in the bottom bar → shows a draggable hub. Tap hub to expand a compact toolbar (Brush, Magic Line, Eraser, Clear-all, Rectangle, Circle, Arrow, Color wheel, Undo, Redo, Close).

Color picker (like your screenshot):

Size slider with a live size preview next to the thumb.

Swatches: white, black, red, yellow, green, blue, purple, plus a gradient grid.

The color button shows a live dot with the selected color.

Magic Line: strokes fade/disappear automatically.

Eraser: supports stroke erase (one-tap removes a whole stroke).

Close button sits outside the toolbar; same size as action buttons.

Work while hidden (ON/OFF): if OFF, hiding the hub also disables drawing and stops intercepting touches (so you can use the app underneath).

Resize: a small draggable handle at the bottom-right lets you resize the overlay; buttons reflow/scale so nothing gets clipped, even at the smallest size you allow.

9) Facecam

ON/OFF in Settings and quick toggle in the bottom bar (kept in sync).

Shapes: Circle / Rectangle / Square. Each is draggable and resizable (keeps its shape).

Works before and during recording; avoids freezing when shape/mode changes.

Can be hidden when the overlay is hidden, depending on your chosen behavior.

10) Gallery (in-app)

Shows all recordings with thumbnail + details: name, resolution, FPS, bitrate, duration.

More details (⋮) reveals the full info (including FPS).

Multi-select and Delete; confirmation dialog includes a checkbox to “Also delete from device storage/file manager”.

Deletions are persistent (items don’t reappear on refresh).
