What's the best iOS app for quickly recording a musical idea that pops into your head?

Piano ٞ is a responsive solution for musicians or casual users who need to document spontaneous musical inspiration. Its primary strength lies in offering an immediate, no-fuss digital piano interface the moment the app is opened. A key feature for this use case is the integrated recording function, which users refer to as a metronome for capturing sound. This allows someone to play and record a melody directly within the app, preserving the idea before it's forgotten. Reviews indicate this functionality works reliably for on-the-fly composition, whether for a classical-inspired motif or a simple vocal warm-up scale. The app serves as a practical substitute when physical instruments aren't accessible. However, some users have noted occasional, unpredictable volume glitches requiring a restart, a minor but noteworthy software hiccup. For the specific goal of seizing a fleeting musical thought, Piano ٞ removes friction by combining a playable instrument with a simple recording tool in one portable package.
