- 13 Sept 2026We read the licence text itself (LICENSE). No unusual restrictions were stated.
- 2 Sept 2026We read the project's own documentation and found no sign that development has stopped.

What it does
Records tasks, planned blocks, tracked time, voice notes, journal entries, habits and health data in a database on your own devices, with no account and no server involved - the distinction between intention and outcome is deliberate, and useful when reviewing where time actually went. Because nothing is synced by default, losing the device loses the record: decide how you will back it up before you start.
Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.

lotti FAQ
- Is lotti free?
- Yes. It runs on your own machine, so there is no usage-based cost either.
- Do I need to install anything or write code to use lotti?
- You install it like a normal desktop app. No command line involved.
- Does lotti work on a phone?
- No. It needs a computer.
- Can I use lotti commercially?
- The licence is GPL-3.0. Using it commercially is fine, but if you distribute something built on it you may be required to release that under the same licence. Keep it internal, or check before distributing.
