How it works

01 / RECORD

Record throughout your day

Had a coffee. Went for a run. Took magnesium. Just tap and talk. A few seconds per note. No forms, no checkboxes, no sitting down to write. tinh works with however you naturally describe things.

Lifestyle database in.
Your triggers out.

Your data · your patterns
SPEED

Seconds, not minutes

Most lifestyle tracking apps ask you to fill out forms or tap through menus. tinh takes a voice note or a few typed words and does the rest. Transcription, categorization, and structuring happen in under a second. Entirely on your device.

MEMORY

Learns how you talk

Correct a categorization once and tinh remembers. Your nicknames, your shorthand, the way you describe your morning routine. The ML models adapt to your vocabulary. It gets smarter the more you use it.
