Kifuku 起伏 · version 1.0 · last updated: 6 September 2026

I write everything myself, so you get a reply from me — usually within a few days.

Fastest route: jakub.dwojak+kifuku@hotmail.com. Inside the app, under Settings, there are ready-made bug report and suggestion forms — they add the app version and device model for you.

I found a mistake in the content

This is the report I care about most. Tell me which word, what accent the app showed, and what you believe is correct. The accent data comes from UniDic and can differ from other dictionaries — if you have a source at hand, name it.

There is no recording for an entry

For some entries the button says "coming later". That is not a failure: we have as many recordings as an open source could give, and the app deliberately uses no speech synthesis — the system does not guarantee it will read 箸 and 橋 differently, and that difference is the whole point.

I lost my purchase

The purchase screen has "Restore purchases". The purchase belongs to your Apple ID, so it comes back on any device you are signed in on.

I changed devices

Progress lives on the device, not on a server. Settings has a progress backup — make one on the old device and load it on the new one.

The app is not working

Tell me what happens and on which screen. The version and build are at the very bottom of the Settings screen — copy them across, or use the in-app form.
