shapesynth vs Ringtone Composer

Shape is a polyphonic synthesiser allowing the user to draw the shape of the oscillator waveform. The first half of the oscillator is represented by 32 blocks and the second half is its mirror, generating all sorts of possible raw retroish sounds. 16 pages per oscillator allows to interpolate between different shapes. Add effects like arpeggio, stereo delay and a resonant filter and record your sounds on a classic tape. Modulate any parameter with keyboard, MIDI MPE or the device accelerometer. Connect to other apps with AudioBus, IAA, AUv3 and midi. +++ 16 voice polyphony +++ 2 oscillators, draw your own shape +++ 3 oscillator mixing functions (add, subtract or multiply) +++ Lfo modulation with ADSR: envelope, pitch, duty cycle, square, page or filter +++ Record on tape with infinite overdubs (save, load, import, export) +++ Arpeggiator +++ Stereo delay +++ Resonant filter (low, band and high pass) +++ Modulate any parameter using keyboard, MIDI MPE or accelerometer (Built in or Sphero) +++ Mini linear sequencer with euclidean rhythm +++ On screen 25 key stylophone style keyboard +++ AudioBus, Inter App Audio and AUv3 +++ Ableton link or AUv3 host sync +++ CoreMIDI, IAA MIDI, Bluetooth MIDI, limited MPE and MIDI out +++ Audio Paste, files app drag’n drop or open with

Write your own ringtone, even if you have never played a note. Ringtone Composer teaches you music through short games, then lets you use what you learned on your own melodies. LEARN MUSIC LIKE A GAME Play through 30 levels in 5 worlds. Each one teaches a real idea in a sentence, then lets you try it: • Up or Down: train your ear to hear pitch • Echo: watch the pads and play the phrase back • Beat Catch: tap falling notes on time over a live band • Spot the Note: find the one that doesn't belong • Happy or Sad: hear the difference between major and minor • Finish the Tune: write an ending that meets the goals Earn stars, climb from Humming Beginner to Maestro, and unlock a new sound style with each world. DAILY TUNE A new unfinished melody every day. Complete it and keep your streak going. FIVE WAYS TO START • Hum It: hum or sing, and the app finds the key and writes the notes • Name Tune: every name makes its own melody • Roll the Dice: pick a mood and get a fresh idea • Retro Keypad: compose on a number pad, like the phones of 1999 • Blank Melody: start from an empty grid A STUDIO WHERE YOU CAN'T PLAY A WRONG NOTE Notes stay in key, so everything sounds right. Add chords and drums, change the feel, and switch between 8 styles with one tap: Retro Phone, Music Box, Lo-Fi Keys, Marimba, 8-Bit Arcade, Guitar, Orchestra and Synthwave. All the sounds are made by the app itself. ONE MELODY, THREE TONES Save a matching set: a ringtone, a short text tone, and a wake-up alarm that starts soft and builds up. On iOS 26 and later you can set them from the Files app with Use as Ringtone. On earlier versions, the app shows you how with GarageBand. PRIVATE BY DESIGN No account needed. Hum It measures your voice on your device, and the sound is never saved or sent anywhere. The app is free and supported by ads.
