FlowTight vs Lacuna

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.

Lacuna turns a short idea into song lyrics and can send them to its music generator to create a track with AI vocals. The editor supports line-by-line rewrites, syllable counts, automatic rhyme highlighting, and rhyme suggestions ranked by meaning. It supports nine languages, with phonetic rhyme support for English, Spanish, Chinese, Japanese, and Korean. Automatic snapshots let users restore an earlier take after AI edits. Lacuna describes the workspace for songwriters, rappers, topliners, producers, and first-time writers, and says generated or edited lyrics may be recorded, released, and used commercially. The free plan provides 120 credits per month without requiring a credit card; each lyrics AI use costs five credits, and unused credits do not roll over. Pricing lists paid service from $9.50/mo (annual), while Basic is $19 a month. Audio downloads require a subscription, and credit packs alone do not include them. The developer API requires Pro or Ultra and uses credit-based billing. Lacuna lists web, iOS, extension, and API platforms.
