TodoLines

TodoLines — daily habits, one tap at a time.

TodoLines is a minimalist tracker for the things you want to do every day, every other day, or on specific weekdays. Each task is a row of day-cells: tap to mark done, tap again to mark missed, tap again to skip. Watch your week fill up at a glance.

No clutter. No gamification noise. Just your habits and a clean grid.

What you can track

• Drink water, take vitamins, exercise, meditate — any daily routine

• Weekly chores (cleaning, laundry) on a fixed cadence

• Specific-day habits (yoga every Tue/Fri, language class on Mondays)

• Anything that repeats and that you want to see a pattern of

Two scheduling modes

• Every X days — set the cadence (1 = daily, 2 = every other day, 7 = weekly). After you mark a task done, the cells in between auto-fill so the row stays readable.

• Specific weekdays — pick any combination of Mon/Tue/.../Sun. Off-days display as neutral dots.

Built for the long run

• Streaks — current and best streak per task, so you know what you're protecting.

• Heatmap stats — a GitHub-style yearly grid for each task, see your consistency at a glance.

• Smart sections — tasks group automatically into "To do today", "Done", "Not today", and "Paused", so the most relevant ones are always at the top.

• Pause & resume — going on vacation? Pause a task and the gap fills with neutral marks instead of looking like you forgot.

• Custom symbols — add your own emojis to a task's cycle (e.g. "💪" for a hard workout day, "🧘" for a light one).

Reminders that respect you

• Optional per-task notifications at the time you choose

• One-tap "Done ✔" action button right in the notification — no need to open the app

• Optional end-of-day summary if you still have unchecked tasks

• Reminders are silenced automatically when the task is already done or not due today

Sync & privacy

• Anonymous account at first launch — no signup, no email, fully usable in seconds

• Optional Google Sign-In to sync across devices

• Your data lives in your private Firebase space; nobody else sees it

• Works offline — changes sync as soon as you're back online

• Delete your account from inside the app whenever you want

Thoughtful details

• Past cells are locked by default to prevent accidental edits — tap the 🔒 to unlock

• A "fill past forgotten cells" action for when you come back after a few days off

• Today-only filter to focus on what's left for the day

• Light and dark themes following your system settings

• Available in English, French, and Spanish
