## What is tinh logbook?

A log book that reads plain language. Write or say an entry the way you'd say it out loud, and the app works out the structure itself.

"Two eggs and coffee, then a 30 minute run" is a complete entry. No fields, no menus, nothing to pick off a list.

WHAT IT PULLS OUT
Food and drink, with amounts. Exercise, with duration and intensity. Supplements and medication. Sleep. Mood and symptoms. Everyday actions, with times attached.

CORRECT IT ONCE
Tap anything that landed wrong and fix its category, name, time, or amount. tinh remembers the correction and applies it the next time you use that word. The longer you use it, the better it gets.

IT RUNS ON YOU
No gen AI. No reading your entries. A local NLP and ML stack that works on a plane and works well. Entries are stored on your device. There's no account to create and no server for us to leak.

SYNC WHEN YOU WANT IT
iPhone and Mac talk to each other over your local network, on your terms. Nothing passes through our servers, and nothing syncs in the background without you.

YOUR DATA STAYS YOURS
Export is never locked behind a purchase. Take your data out whenever you want, in an open format.

PATTERNS, ONCE YOU'VE EARNED THEM
After a couple of weeks, tinh starts surfacing correlations between what you log and how you feel. Early on it's mostly a log book, and it says so rather than inventing.

PRICING
$34.99, one time, after a 14-day free trial. No subscription. iPhone and Mac. After the trial you can still read and export everything; you just can't add new entries until you buy. Includes unlimited use and updates for 1 year.

## Version history (last 3 releases)

### 1.2 — 2026-09-22

NEW: GAMES

tinh now has a Games tab with five short daily games. Each one takes a minute or two. Your results land in Insights next to everything else you log, so you can see how they line up with your sleep, food and training.

- Puzzle: one grid puzzle a day. Work out the rule from the examples, then fill in the answer.
- Reflex: tap the circles as they light up. Three modes: Marathon, Sprint and Steady.
- Symbol Match: match symbols to digits against the clock.
- Word Recall: read a short word list in the evening, then type back what you remember the next morning.
- Minute hold: press and hold, and let go when a minute feels like it has passed. No clock to look at.

The games are optional and still in beta. Play them when you feel like it, skip them when you do not. Reminders for them are off unless you turn them on.

ALSO NEW
- Item patterns: the Temporal tab now starts from one item and shows when it tends to happen.
- A longer first-run walkthrough that covers fixing mistakes, your dictionary and your metrics.
- Old entries with unreliable timestamps no longer pile up at noon and midnight in Temporal.

FROM 1.1, IN CASE YOU MISSED IT
- More honest numbers in Insights, and metrics where lower is better are now read the right way round.
- The date picker opens that day's entry and updates it. One entry per day.
- In quick log, your timeline stays visible above the keyboard while you type.
- Streaks are gone. You now see a plain count of recent logged days.
- The Patterns tab no longer freezes while it calculates.

If you sync with a Mac, update both to 1.2. The two versions need to match to sync.

### 1.1 — 2026-09-15

Improvements to how tinh reads your entries and finds patterns.

- Insights now show honest statistics and understand when lower is better
- Patterns tab no longer freezes on large logs
- Quick log keeps the timeline visible while you type (iPhone)
- Composer edits the day you have selected, one entry per day
- Fixes for entry times, midnight rollover and composer overflow

Sync format has changed. Update tinh on all your devices for sync to work.
