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. Download Mainichi on the App Store: https://apps.apple.com/us/app/ma...

Who hunted Mainichi?
Mainichi was hunted by Michał Paczyński. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
