Using Robo Flute you can enter a musical phrase and find out how it sounds like when playing with a real flute. Insert a sequence of notes and set the fingering and timing for each note using the keyboard. Robo Flute will then play it for you. You can select from a variety of flutes including Native American Flute, Quena, Quenacho, Bansuri, Zampoña Panflute, Recorder, and Ocarina. An interesting feature of the app is that you can easily convert the fingering of your written song from one flute to another flute as much as it is convertible. In order to do that, write your song for one flute and simply open it for another flute. Even if you have no knowledge in reading music, you may still be able to write your music easily using the fingering, timing, and editing tools in the app. You may save or print your written music as well. The app includes important scales, exercises, as well as improvisation tool which can help improve your finger dexterity. Also, you can play the virtual instrument in the app if you have no access to a real flute. The premium version enables the phrase save, print, export, and import features. It unlocks all exercises, and removes all ads from the app. The in-app purchase for accessing the premium version is a single-time payment which never expires.

Flip is a sample-based mobile music studio that was designed for a fast and intuitive work flow. Import your own sounds via AirDrop or the Files app, or record sounds directly with your device's microphone or a connected iOS interface. As soon as you record a sound it’s available to be played on drum pads as well as being mapped across a keyboard. Sounds can be subtly shaped or entirely transformed using the built-in effects and easy-to-use editing tools. You can record a quantized or unquantized performance on the pads or keyboard. There is also a full piano roll where you can enter and edit notes and velocities. Record knob movements or draw automation by hand to bring even more life to your sounds. Every automation lane can also have its own independent length, for polymetric and generative music possibilities. Create up to 16 different sections for your song and drag and drop them into any order to create your arrangement. Mixing and mastering tools allow you to finish a full track without ever leaving your phone. You can export your full track, or hit the tape icon and record the live output of the app while you tweak anything on the fly. Both options allow you to capture individual track stems as well! A performance page lets you trigger your patterns live while controlling a global filter, assignable pitch bends and reverb sends, and a random fill generator. Artist packs are available in-app at $3.99 or less, which include original sounds and projects from Andrew Huang, Cuckoo, Chuck Sutton, Kilamanzego, Pusher, and more on the way all the time.
