Seconds, not minutes

Open tinh, say what is going on, and you are done. No forms, no typing, no blank page. A note takes about ten seconds, so you actually keep it up.

It sorts itself out

On-device ML reads each note and files it into the right categories. Correct it once and it learns your wording. Nothing is sent to a server to do this.

A correlation heatmap of habits against how you feel

Patterns you can act on

Over days and weeks, tinh surfaces the connections between what you do and how you feel, so you can change one thing and watch what happens.

How it works

Three steps, all on your phone

Step one

Speak a note

Through the day, open tinh and say what is happening. Slept badly, big coffee, headache by noon, good focus after a walk. Whatever you would notice.

Step two

tinh structures it

On-device ML turns your words into clean, categorized data points. No tags to pick, no fields to fill. It learns how you talk over time.

Step three

See what connects

tinh shows you the relationships in your own data on iPhone, with a deeper view on Mac. The patterns you can never hold in your head all at once.

Private by design

Your life stays on your device

tinh processes everything locally. The proof is simple: turn on airplane mode and the app keeps working. Capture, categorize, and view your patterns with no connection at all.

  • No account to create and no password to remember.
  • Voice notes and data are processed on-device, not in the cloud.
  • Works fully offline, so you can see for yourself nothing is being sent.
  • You own your data and can delete it at any time.
From the developer

I am the solo developer behind tinh. I built it over the last two years because I wanted to understand my own patterns without handing my private life to a company server.

Every voice note stays on your device. There is no growth team and no data to sell. It is one person trying to make the honest version of this, and the beta is how I get it right with you.

Questions before you sign up

Is it really free?

Yes. The beta is free while it runs. When tinh launches on the App Store it will be a subscription, but beta testers get plenty of notice and no surprise charges.

Is my data safe?

Your notes and data are processed on your device, not in the cloud. There is no account and nothing to sell. Turn on airplane mode and the app still works, which is the easiest way to prove it to yourself.

What platforms does it run on?

The beta is iPhone and Mac only. The iPhone app is the main surface, and the Mac app is a deeper view of the same data. Android and Windows are not supported.

What is the catch?

There is not one. It is an early beta from a solo developer, so you will hit rough edges and your feedback genuinely shapes it. In exchange you get the app free while it is in testing.

What is TestFlight?

TestFlight is Apple's official app for trying beta apps. After you sign up we email you a link, you install TestFlight from the App Store, tap the link, and tinh installs like any other app.
