OneTimeThe desktop habit tracker you buy once — streaks, heatmaps and schedules that match real life.
Habitify charges $5/month, forever, to store your checkmarks on their servers. Streakly is $15 once: habits with schedules that match real life, numeric goals, a streak engine that's actually fair, GitHub-style heatmaps and native reminders — 100% local, zero cloud, zero telemetry. Your habits are not a subscription.
Streakly in 60 seconds
Everything in the box
Local habit tracking with a fair streak engine, GitHub-style heatmaps and reminders.
Schedules that match real life
Every day, specific weekdays, or N times per week — with an icon and color per habit.
Numeric goals
"8 glasses of water", "50 pushups" — increment through the day; only hitting the goal completes it, partial counts still tracked.
A streak engine that's fair
Weekday-only habits survive the weekend, N-per-week habits count weekly quotas, and today doesn't break your streak just because it isn't done yet.
Vacation mode
Skip days freeze your streaks instead of killing them.
GitHub-style heatmaps
A year heatmap per habit plus an all-habits month view with per-day dots.
Reminders
Native OS notifications at the times you choose.
Stats + notes
Current & best streak, total completions, completion % over 30/90/365 days — and a journal line on any check-in.
Your data is a JSON file
Human-readable, in your user folder — JSON export/import for backup, CSV for spreadsheets. No network calls at all.

Fair questions
Is it really free on GitHub?
Yes — MIT source at github.com/bensblueprints/habit-tracker-mvp. $15 buys the packaged Windows installer and updates.
Why is the streak engine "fair"?
Because most trackers punish you for their own bad math. In Streakly, a weekdays-only habit doesn't break over the weekend, an N-per-week habit counts weekly quotas across week boundaries, skip days freeze streaks, and an unfinished today never kills a streak prematurely. The engine is a pure zero-dependency module with its own test suite.
Is there a phone app or sync?
No — Streakly is desktop-first with no cloud, which is exactly why it can promise zero network calls. Your entire history is one JSON file; sync it yourself via Dropbox, Drive or Syncthing if you want it on two machines. If phone-first tracking matters most, Habitify is the better fit.
Do reminders work?
Yes — native OS notifications at whatever times you set per habit.
What if the app disappears?
Nothing happens — your data is a human-readable JSON file on your own disk, and the MIT source builds the app anywhere Electron runs.
