Spark - Habit Tracker

A Good Bug

About this app

Spark is a fast, offline-first habit tracker built to help you build routines that actually stick — no clutter, no guilt-trip streaks, just clean daily tracking that works with your life.

Whether you're building a morning routine, tracking water intake, meditating, or working toward a bigger goal, Spark adapts to how you actually track things — simple check-offs, counted quantities, or timed sessions.

WHY PEOPLE SWITCH TO SPARK

✓ Works fully offline — your data lives on your device, always available, never waiting on a server
✓ Home screen widgets that update in real time — track habits without even opening the app
✓ A floating timer overlay so you can time a habit while using any other app
✓ Yearly heatmap view of every habit, so you can see your consistency at a glance
✓ Private cloud backup to your own Google Drive — we never see or store your data on our servers
✓ A calm, distraction-free interface with dark and light themes, and 15 accent colors to personalize every habit

THREE WAYS TO TRACK, YOUR CHOICE
- Simple habits: quick yes/no check-offs for things like "meditate" or "no sugar"
- Count habits: track quantities like glasses of water, pages read, or reps completed
- Timer habits: track duration for things like workouts, reading, or focus sessions — with a live floating overlay so the timer stays visible over other apps

STAY CONSISTENT, NOT OVERWHELMED
- Daily, weekly, monthly, and yearly views of your progress
- Current streak and best streak tracked automatically for every habit
- Completion rate and total check-ins, skips, and misses — real numbers, not vague scores
- Smart reminders at the times you choose, with the option to sync them to your phone's calendar

HOME SCREEN WIDGETS THAT ACTUALLY HELP
Add single-habit, weekly, or monthly widgets right to your home screen. Check off a habit, glance at your streak, or see your week at a glance — without unlocking into the app.

YOUR DATA STAYS YOURS
Spark stores everything locally on your device first. If you choose to back up, your data goes straight to your own private Google Drive folder — encrypted, accessible only to you, never to us. No account required to use the app.

BUILT FOR PEOPLE WHO WANT TO ACTUALLY KEEP THEIR HABITS
Spark isn't trying to gamify your life with badges and pressure. It's a clean, honest tool for building routines you'll still be doing in a year — with the streaks, heatmaps, and widgets to prove it.
