The same four promises

Different apps, one way of making them.

Your device first
Your things stay on your phone or your computer. No analytics and no tracking.
Sync if you want it
On Android, a free account copies your data to your other phones. Delete it from the app any time.
Out in the open
Every release is on GitHub with its notes, and the Android apps update through F-Droid.

By day I teach management to MBA and business students at St. Joseph’s College (Autonomous) in Tiruchirappalli. I came to management from technology, with Computer Science at Karunya and then an MBA, so I still like to build the things I teach about.

I make apps I want on my own phone and computer. Prompt Heart came from good prompts lost in chats and screenshots. Watch Heart came from wanting one diary for the film on Friday and the anime at 1 am. Kural Heart puts a couplet of the Thirukkural beside a page to write, each day.

On Windows, Frame Heart cleans corner marks off AI pictures and video, Still Heart saves whole galleries, and Rush Heart saves videos and audio. All six apps are free.

Ideas, bugs and questions are all welcome. I read every message.

Questions

Are they really free?

Yes. Every app is free, with no ads, no subscriptions and no paid extras, and that won’t change.

Do I need an account?

No. The Windows apps have no accounts of their own. On Android everything works without one, and an account only adds sync, so your prompts or your diary follow you to another phone.

Where is my data kept?

On your phone or computer first. If you sign in to an Android app, a copy is kept in your own private account, which only you can read. Kural Heart has no account at all: its journal stays on your phone, and its backups are locked with a passphrase only you know. Each app’s privacy policy lists exactly what is kept: Prompt Heart, Watch Heart, Kural Heart.

How do I install them?

On Android, add the app’s F-Droid repository once and updates arrive like any other app, or download the APK from GitHub. Kural Heart is an APK from GitHub for now, and smaller updates arrive inside the app. On Windows, download the one file and open it. Windows may warn you, because the apps aren’t code-signed; each app’s site explains what to do.

Are they on Google Play or iPhone?

Not yet on Google Play; it’s next. There is no iPhone or Mac version.

How do I delete my account?

In Prompt Heart or Watch Heart, open Settings and choose Delete account. Each app’s website also explains how to ask for deletion without the app.
