Both are correct — they belong to different systems. Kunrei-shiki, taught in Japanese schools, gives densya; Hepburn, used on passports and station signs, gives densha. You choose which system to practise on the home screen. If you type the spelling from the other system, the app does not mark it wrong: it tells you which system that spelling belongs to.
Press the “ô” key on the on-screen keyboard: it adds the mark to the vowel you typed last (o becomes ô). In a desktop browser you can also use your physical keyboard.
You can remove ads permanently with a one-time purchase from the home screen. If you would rather not buy anything, watching a rewarded video to the end pauses ads for a limited time.
Use “Restore purchase” on the home screen after signing in to the same App Store / Google Play account you originally purchased with.
Users in the European Economic Area and the United Kingdom are shown a consent form, and can change their choices at any time from Settings → Ad privacy settings in the app. Elsewhere, use your device settings to reset the advertising ID and opt out of personalised ads.
Your best scores and settings are stored only on your device and are never sent to a server, so they cannot be carried over if you delete the app or move to another device.
