6 appsSort out the week's timetable, tidy up a photo, try out an instrument or plan a trip — each app does exactly one job, with nothing uploaded, no adverts and no account to create.
ReasoningHotAn IQ-style test in six parts — matrices, number series, scales, 3D rotation, a memory span and symbol coding. The questions are new every time, each one comes with its worked answer, and the result is a profile of five abilities rather than an IQ number nobody can back up.

NewTen instruments with no audio files at all — every sound is computed from a physical model of the object, so you can rebuild the instrument itself and hear it change on the next note. Play them, or let each one play its five arrangements.
10 instruments · no samples · WAV + MIDI out

VideoBuild a five-minute follow-along run video for one named viewer: pick a character and a scene, place the obstacles (or let the app deal them, differently every time), preview it, and export in every quality at once — with music, in the background.
