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
