The app consists of two parts. On the one part where you could practice Japanese letters, that used in the name of Prefecture in Japan. On the other part where you could make sure where it is on a simple map by selecting a prefecture you want to see. You can select English or Japanese on some of pages. It would be good thing for Japanese learners since you could practice Japanese letters and also make sure where each prefecture is using a simple map. Enjoy writing Japanese letters!

SpeakIt AI's advantage is ads (none vs shown) and update cadence (every 5 days vs every 12 months). On price and device support there is nothing between them.
