Fuellito: Button Accordion

Play a diatonic button accordion on your phone — and finish the song without an ad popping up in the middle. Fuellito gives you 34 treble buttons, 12 bass buttons and a bellows bar that changes every note when you close or open it, just like a real squeezebox. Pick a song, follow the golden lights, and learn it button by button. WHY PEOPLE SWITCH TO FUELLITO • No ads on the playing screen. Ever. Not between notes, not in the middle of a song. • Every tuning and every sound is unlocked. Nothing to buy to keep playing. • Bass and chord buttons for the left hand. • Several buttons at once for real chords, and the sound starts the instant you touch. PLAY LIKE A REAL BUTTON ACCORDION • 3 rows: 11 / 12 / 11 buttons, staggered like the real instrument • Hold the bellows bar to close (push), let go to open (pull) — each button plays two notes • 6 tunings: GCF, FBbEb, EAD, F#BE, ADG, BbEbAb • 3 sounds: Classic, Bright (musette) and Soft • Note names as Do Re Mi, C D E or button numbers • Button size from S to XL, left-handed layout LEARN SONGS WITH LIGHTS • The next button glows gold and the bellows bar tells you which way to squeeze • Listen first with ▶, then play it yourself • Auto mode: tap anywhere and the song moves forward — great for kids and first-timers • Earn up to 3 stars per song and keep your daily streak going • Folk songs and classics like La Cucaracha, Jingle Bells, Ode to Joy, When the Saints and Amazing Grace, plus major scales RECORD YOUR OWN MELODIES Tap Record in free play and the buttons you press are saved.

SMALL THINGS THAT HELP • Works offline — no account, no sign-up • Home screen widget with the song of the day • One gentle daily reminder you can turn off • Light and dark themes Fuellito is for anyone who wants to try the button accordion before buying one, practice away from the instrument, or just squeeze out a tune on the bus.
