Android. Flutter (Material 3), surface-driven; no backend. All decisions below must stay achievable with the app's flat, offline, single-accent system.
Loopweek is a free, fully open-source weekly to-do app whose entire value is constraint: one screen, seven days, nothing else. The week is the screen; the accordion keeps one day open at a time; tasks never roll over. Success is planning and completing a week without ever leaving one screen and without the app asking anything of the user.
Mode: Operate — the user completes the task of planning/checking the week; scanability, predictability, and the real everyday usage scene outrank expression. Brand lives in precise details, not decoration.
A flat, quiet system where constraint itself is the signature: one accent color, dividers instead of shadows, tight condensed display type, generous near-empty space. Nothing vies for attention because the week is the only thing on screen.
- Accent (one, per user): default orange
#F4511E; alt pink#E91E63, blue#1E88E5, green#43A047. The same accent drives active checkboxes, selected segmented option, toggles, primary actions, and the home widget. (seelib/core/theme/accent_colors.dart) - Light: scaffold off-white
#F2F2F2, surface white#FFFFFF, divider#E0E0E0. - Dark: scaffold near-black
#121212, surface#1E1E1E, divider#2A2A2A. - Never pure black/white; flat surfaces, elevation 0, dividers do the separating.
Bold, tight-tracking, condensed sans-serif for day headers and section titles (heavy weight,
slightly reduced letter-spacing, e.g. -0.6; approximated with Material stack offline). Body
is plain and quiet. (see lib/core/theme/app_theme.dart)
Moderate corner radius (~10–12dp); toggles stay pill; no shadows, no gradient, no glass. Interaction is tap + long-press only; no swipe.
The logo is a seven-segment open loop: a bold ring broken into seven chunky rounded
segments — the seven days — with a deliberate opening at the top so it reads as an open
loop that returns (the weekly cycle, one screen, no escape). The leading segment after the
opening is "today" in the default accent orange #F4511E; the other six are the ink
#121212. It sits on the flat off-white tile #F2F2F2.
- Flat, single-accent, no shadow/gradient — it obeys the same system as the app surfaces.
- Ownable, not a generic check or calendar: the loop of seven days is the product's exact idea.
- The mark is the brand; there is no text in the launcher mark (the launcher label is the name).
"Seven rounded ticks arranged in a circle, open like a loop at the top; the first tick after the gap is orange — today — while the rest of the week is dark."
- Raster identity:
docs/brand/logo-mark.png(1024, light),logo-mark-transparent.png. - Generator (source of truth, rerun to regenerate all densities):
docs/brand/generate_logo.py— outputs every Android density + adaptive foreground/background. - Installed Android assets:
android/app/src/main/res/mipmap-*/ic_launcher*.pngand the adaptivemipmap-anydpi-v26/ic_launcher.xml(background@color/ic_launcher_background).
- Do not add gradients, shadows, gloss, or a second color to the mark.
- Do not put the wordmark inside the launcher icon.
- Do not reinterpret "today" in a third color; the mark stays orange-on-ink on off-white.
- Single-open-day accordion, today expanded by default, tapping a day swaps it.
- Cards are flat white/
#1E1E1Ewith elevation 0 and a 12dp radius; dividers separate rows. - The one accent appears only where action or selection lives.
