Questions
How do I install them?
Daybook and Finnish tutor are in closed testing on Google Play, so they don't show up in search
yet. Join the tester group for the app, accept the invitation, and the listing opens for
your account. Use the account your phone's Play Store is signed in to. Steps and links are
on the Daybook and
Finnish tutor pages. English tutor is on its way to
Google Play and the Microsoft Store; its page has the
news.
What do they cost?
The browser and Android versions are free. The Windows builds are $2.69 each,
sold on the Microsoft Store.
There's no subscription either way: the AI
features run on your own free Gemini key.
Where is my data kept?
In the app's own storage on your phone or computer. There's no MAIA
Architech server and no account to create.
Do the apps show ads or track me?
No ads, no analytics, no trackers, no crash reporting.
Which platforms are supported?
Android and Windows for every app, plus Daybook in the browser. The Windows
builds are on the Microsoft Store, and the two tutors pair phone and desktop with a QR
scan.
