Touchophone vs DoReQuiz

Touchophone turns your screen into a synthesizer. Touch the keys, twist the knobs, and see what happens. It's the kind of instrument you pick up and never want to put down. Play a melody. Stack notes into chords. Crank the filter. Add some delay and let it echo into space. There are no rules — just sounds waiting to be discovered. WHAT'S INSIDE - A 2-octave chromatic keyboard you play with your fingers - 4 notes at once — hold chords, play melodies - Sub-oscillators to fatten up your sound - A filter knob that goes from warm to screamy - Delay that repeats and fades like an echo in a tunnel - An LFO that wobbles everything in the best way - Envelope controls to shape how notes start and fade EXPRESSION STRIP - Bend notes up and down - Sweep the filter with your finger (wah!) - Add vibrato for extra flavor THE SMALL STUFF - Play with multiple fingers at once - Slide between keys - Use the expression strip while holding notes - Works on iPhone and iPad - No ads. No subscriptions. No account. Just sounds.

DoReQuiz turns musical listening into a tactile game. Listen to a short melody, find the notes on the keyboard, and progress round after round. The app is designed to train musical hearing without a complicated interface: a clear keyboard, immediate feedback, several difficulty modes, and a playful visual style inspired by small electronic instruments. Included modes: - Guided mode: keys light up to show the melody. - Easy mode: short phrases on one octave. - Normal mode: longer and more demanding melodies. - Instrument quiz: listen to a sound and choose the matching image. - Chords: find several notes played together. - Freestyle: play freely on the keyboard. DoReQuiz is made for beginners, children, curious musicians, and anyone who wants to practice listening, melodic memory, and note recognition in a direct way. No theory required to start: listen, play, repeat.
