FlowTight vs RhymeFlux

FlowTight is an iOS music creation app for developing song ideas through lyrics, beats, and vocal recording. Its AI Lyric Generator makes four bars from a topic or theme in a chosen flow style, while the songwriting workspace provides song sections, a syllable meter, rhymes, a thesaurus, and autosaving. To create a beat, users can hum or beatbox a rhythm and select a vibe; the app generates a 30-second beat and can use an optional photo for inspiration. Users can also import a beat, record vocals over it, and punch in at a point in a take to repair a line. The free plan includes voice recording, lyric generation, and three AI beat generations per month. FlowTight Pro adds 30 AI beats per month, the full Beat Maker, recording over any beat, MP3 export, vocal effects, and commercial license documentation. Pro costs $7.99 a month or $59.99 a year. FlowTight requires iOS 16 or later and recommends iOS 17 or later for AI features; Android support is planned.

Live rhyme highlighting matches words by sound for US, UK, Australian, and Canadian English. A syllable counter and Beat Grid flag bars that run long relative to a section.
