## What TriLog does

TriLog records energy, mood and activity with one tap each, plus short notes for meals, health observations, journal entries and daily habits.

It shows your day on one timeline and weeks of mood, energy and sleep side by side, with weather, pollen and barometric pressure next to your entries.

With TriLog Pro, you can add your own trackers, Apple Health metrics and hour-by-hour Screen Time.

## Who TriLog suits

- People who want to see what lines up with their good and bad days
- Self-trackers who log more than a watch can measure

One limit: TriLog Pro is a subscription that starts with a 30-day free trial.

## TriLog and AI

Built with AI, as the maker says: The maker says he prototyped the first version in Rork, then moved to Xcode for more control. ([source](https://news.ycombinator.com/item?id=47213136))

## What TriLog costs

Free tier: Free plan. TriLog is free to use for logging; TriLog Pro adds extra features as an in-app purchase.
