Ember pairs a heatmap habit tracker with one motivating spark a day — built as two fully native apps (SwiftUI on iOS, Jetpack Compose on Android) that run entirely on your phone. No accounts, no servers, no feed. Just you and your streaks.
Every habit gets a year-at-a-glance heatmap, right on the home screen of the app. One tap checks off today — and one more cell lights up.
A new spark every day, from 368 curated ones — in a shuffled rotation that never repeats until you've seen them all. Add your own, or generate new ones with on-device AI.
No accounts, no ads, no analytics, no servers. Everything — habits, sparks, even the AI — lives and runs on your device.
Track simple done-today habits or counted ones like glasses of water. Each habit's detail screen shows your streak, your best, your 30-day rate — and a month calendar where you can tap any day to fix history you forgot to log.
Every morning Ember deals you one spark from a shuffled deck of 368 curated sparks — and the deck only reshuffles once you've seen every card. Favorite the keepers, write your own, or let your iPhone generate brand-new ones without ever touching the internet.
The heatmap widget puts a habit — and a working check-off button — right on your home screen. The motivation widget shows today's spark, drawn from whichever sparks you choose. WidgetKit on iOS, Glance on Android, native on both.
Everything a habit needs to survive contact with real life.
Current streak, best-ever, 30-day completion rate, and lifetime total — computed per habit, updated the moment you check off.
Forgot to log Tuesday? Tap it in the month calendar. Streaks and heatmaps recompute instantly — honesty encouraged.
Write your own sparks and they join the daily rotation, the widgets, and your library — right alongside the curated 368.
Supported iPhones can generate fresh sparks with Apple Intelligence — deduped, curatable, and never sent anywhere.
A daily spark nudge plus optional per-habit reminders — all scheduled locally on the device, no push servers involved.
System, Light, or Dark — your choice, and the heatmaps follow the effective theme instead of blindly tracking the OS.
Ember has no servers, no analytics, and makes zero network requests. Even the AI that writes new sparks runs on the phone itself.
Ember is one developer's daily driver — the same app written twice, natively, for iOS and Android. The Android app is live on Google Play; the App Store will follow. This page knew first.
