Every habit is a plant. Completing it waters it, and one’s own garden grows along with it. On top of that, more than 150 ready-made routines, streaks that one bad day does not destroy, mood tracking and a holiday mode. No account, no ads, everything on the device. On the Google Play Store since August 2026. The Today view runs in the browser below.
The app has been publicly available on the Google Play Store since August 2026, initially for Germany, Austria and Switzerland. It is free to use, contains no ads and needs no account.
As a subscription or as a one-off purchase. Current prices are shown in the store.
What the app does not do. It creates no account, shows no ads and does not transmit any habits to the outside. It only needs an internet connection for purchases and restoring them. Everything else is in the app’s privacy policy.
Exactly the screen one opens in the morning, including the line of the day. Checking off fills the ring, the streaks count up, and a small garden grows along at the bottom. The 150 routine profiles, statistics, themes, horoscope, holiday mode and the whole garden are in the app. Without Premium, up to three habits run at the same time.
A tool with one clear job – well made, fast and beautiful, with no account and no server of its own.
Every consecutive day counts. The streak is the small daily incentive to keep going.
One tap a day records the mood – over time an honest picture emerges.
Every tile can be tapped: twelve-week trend, strongest weekday and the ranking of the habits – without a graveyard of numbers.
Completed habits make a garden with eleven plant species grow. New species are not unlocked via a menu, but by actually completing the matching habit several times. On top of that, backdrops from spring to starry night and visitors unlocked by progress.
Ready-made templates from “sanfter Morgen” (gentle morning) to “Gym-Disziplin” (gym discipline) – one tap, and the matching habits are in the plan.
A warm line to start every day, in the tone of the chosen profile – eleven tones, 120 days without repetition. Plus a daily horoscope for all twelve star signs.
On holiday, streaks freeze instead of breaking – and a missed day can be repaired with the streak rescuer.
Several colour themes – from Midnight to Sunset to Sakura – to suit one’s own taste.
No account, no servers, no cloud. All data stays on the device, and the backup is encrypted. The app only goes online for purchases and restoring them. Here, privacy is not a setting but the way it is built.
Tendly is deliberately lean: a web app that feels like a native app, from one code base for web and Android.
User interface in React with TypeScript, state management via Zustand with storage on the device (localStorage).
Smooth transitions and small reward animations when checking off – the things that feel good.
Styling with Tailwind, colour themes via CSS variables – a single switch is enough for the entire design.
Capacitor turns the same web code base into the native Android app for the Play Store.
No backend of its own: no server costs, and the habits stay on the device. The app only goes online for purchases via Google Play and RevenueCat.
Data model, streak logic, recommendations and user interface are in separate modules – easy to test, easy to extend.
Published and maintained. What comes next will be decided by what real users do.
Creating and checking off habits, streak and completion-rate calculation, weekly overview and mood tracking.
Tappable analyses, the garden with eleven plant species and a day/night sky, several colour themes and the freemium limit (three habits free).
150 routine profiles, daily message in eleven tones, horoscope, holiday mode, streak rescuer, reminders and encrypted backup.
Testing on other people’s devices, as Google requires before public release. This revealed that one build had accidentally been created with test mode switched on, in which Premium could be unlocked with two taps. It never went into production.
Before submission, a separate review pass covering legal matters, prices, data security, store details and code. Six issues stood in the way of publication, among them a back button that closed the entire app on the first press of the day.
Release granted. Tendly can be downloaded in Germany, Austria and Switzerland – free, without ads, without an account. To the store listing.
Four additional skies for the garden: spring, sunset, starry night and winter. “Nach der Uhrzeit” (by time of day) remains free and the default; nothing that was free before has moved behind the paywall. Also better legibility of the switches in all colour themes and a streak rescuer that also works for weekday habits.
Version 1.0.39 asks once for a rating – on the fifth day at the earliest, only after a good moment, at most every three months. And sharing one’s own garden now appears where one feels proud: on discovering a new plant species and on a perfect day.
Which routine gets chosen, which plant is never discovered, at which point someone stops. Without these numbers, every further feature would be guesswork.
Questions about how it is built, the decisions behind it or how it might transfer to another case.
