Mainichi
Learn Japanese, one prefecture at a time.
Learn 20,000+ Japanese words with a spaced-repetition system built for long-term memory. Playful, gamified sessions under 5 minutes a day — no boring textbooks. Mainichi skips the flashcard grind. Short, low-pressure sessions that fit into a real day — show up, relax into a round of vocab, and let your streak do the rest. Clean cards. Fast sessions. A progress bar that actually fills up. The interface gets out of the way so you can focus on the words.

I like the focus on consistency over intensity. Five-minute sessions with spaced repetition are much more realistic for long-term language learning than trying to cram for an hour every few days.

learning it prefecture by prefecture is a nice hook, most apps just throw generic vocab at you with no sense of place. does the content touch on regional dialect differences at all (Kansai-ben vs standard Tokyo Japanese) or is it standardized Japanese wrapped in a geography theme

The cards feel really clean and the sessions are short enough that I'm not dreading opening the app, which is half the battle honestly.

Love the idea an the implementation!Probably main page lacks some examples from the app before sending user to store.

the prefecture-by-prefecture structure is a nice hook, most vocab apps just throw everything at you in the same order. since Android is coming soon, will progress sync across platforms if someone switches, or does it start fresh on whatever device you're on

Why did you decide on Japanese? BTW, love the idea, actually anything with the learning potential has my upvote! :D

A few months ago, learning Japanese myself, I got frustrated — vocabulary is the foundation of any language, yet most apps skip past it for drills or games. So I decided to build my own.
As of today, Mainichi is live on the App Store. Solo project, built out of love for the language and the craft. Would mean a lot if you gave it a try if you are also learning Japanese - if not, maybe it's a good moment to give it a go!
You can explore Japan prefecture by prefecture as your vocabulary grows. Master a dictionary of 20,000+ words with a spaced-repetition system designed for long-term memory. And battle bosses, hunt treasures, and roll for XP along the way — because learning a language should feel like an adventure.
