Why I built KeepFlame
I spent some time looking at existing habit apps. Many of them are heavily connected: they send data to servers, analyse your behaviour, and try to motivate you through rankings, analytics dashboards, or social features.
That can be useful for some people, but it is not for everyone.
For people who are more privacy-sensitive, or who simply do not want their daily habits tied to an account, I wanted to build something different: a habit tracker that stays offline, keeps data on-device, and uses animation instead of streak counts to keep you motivated.
KeepFlame is my attempt at that — a small app where your habits stay local, but your progress still feels visible and rewarding.
How it works
KeepFlame is built around a simple daily loop:
- Add habits with “Add Task”.
- Use the date chevron to move between months, then pick a day on the week bar.
- Tap Today to jump back to the current date.
You can turn habits on and off for specific days, and check in regularly from the calendar. There is no infinite feed and no inbox of “insights” to manage — the focus is on a small set of habits that matter to you.
Notifications and Live Activities are available so you can see progress and reminders from the Lock Screen or Dynamic Island without opening the app.
Themes and animations
Instead of leaderboards or streak badges, KeepFlame uses animated themes as a gentle form of motivation.
When you keep up with your habits, you unlock and see new frames and scenes. Over time, the app becomes a gallery of small animated moments that reflect your consistency.
Some of the built-in themes include:
- Season
- Medieval
- PixelJapan
- SciFiUniverse
- Futuristic City
At launch, Season is available to all users, while additional theme packs are part of KeepFlame Pro.
You can also watch a short overview of these themes here:
Themes are updated over time so even free users can enjoy new visuals. You can change themes from settings to match your current mood.
Pricing and KeepFlame Pro
KeepFlame offers a Pro upgrade as either a one-time purchase or a monthly subscription. Pro unlocks extra options and more flexibility, while the core habit tracking experience remains available without forcing a subscription.
Purchases are handled by Apple through the App Store. We do not receive your payment details directly. You can restore a previous purchase at any time from Settings → Upgrade → Restore.
Private by design
KeepFlame is designed with a simple privacy rule: your habits and settings stay on your device.
- No personal data collection. We do not collect, store, or transmit your habits or other personal information.
- On-device only. All habit data and settings remain on your iPhone.
- No analytics or advertising SDKs. There is no third-party tracking or ad network SDK built into the app.
Notifications are optional and controlled entirely by you in iOS Settings. Notification content is not sent to any external server.
Your use of KeepFlame is also governed by Apple’s standard End User License Agreement (EULA) for apps downloaded from the App Store. You can read the full text at:
