Play the classic Java mobile games you grew up with. Jemu is a J2ME emulator that runs old-school .jar phone games right on your iPhone and iPad — the feature-phone titles that used to live in your pocket. Jemu ships with no games and downloads nothing. You bring your own legally obtained .jar MIDlet files, import them once, and they run fully on-device with a real on-screen phone keypad. No streaming, no accounts, no cloud — just the emulator core and your own library. WHAT YOU GET - Run classic J2ME (Java ME) .jar games natively on iOS - Import your own .jar files with the built-in file picker - A tidy library that reads each title, vendor and version straight from the JAR - An authentic on-screen keypad: number pad, D-pad and soft keys mapped to MIDP controls - Pick the emulated screen size — presets from 128x128 up to 480x800, portrait or landscape - Fit, Fill or Original scaling, plus keep-screen-on and sound toggles for long sessions PERFECT FOR - Retro gamers chasing the feature-phone titles of the 2000s - Collectors preserving their own legally owned .jar files - Java ME tinkerers who want a real MIDlet runtime in their pocket - Anyone who misses the snake, puzzle and arcade games from old phones WHY NOT JUST USE AN OLD PHONE Your old handset is dead, the screen is cracked and the charger is long gone. Jemu keeps the exact same games playable on the device you already carry — scaled up, full-brightness and touch-friendly — with none of the hardware to hunt down. PRIVACY Everything stays on your device. Your imported games live in the app sandbox, nothing is uploaded, and the emulator runs completely offline. No account and no tracking of your library. FULL ACCESS Jemu unlocks with Jemu Pro, which opens the full app so you can import and play your whole library with no limits. Choose the plan that fits: Weekly, Yearly, or a one-time Lifetime unlock. Prices are shown in-app before you confirm; subscription plans renew until cancelled and can be managed anytime in your App Store settings. Import your first .jar and press play.
