Turn the songs you want to play into your own TAB sheet. FlowySheet is a composition and arrangement tool for guitar fingerstyle players. Pick a mood, tempo, and key, and the app guides you step by step — melody, chords, bass, rhythm — so even beginners can build playable arrangements. 【Key Features】 Guided Composition Workflow Walk through the Composition tab and the app handles song structure, key & scale, chord progression, rhythm, and solo fingerstyle arrangement. Killer Phrase Generator (NEW in v1.3) A one-tap chorus highlight generator in the Analysis tab. Choose from five archetypes: Rise & Fall, Climax Build, Open-String Spread, Cool Ending, Lingering. Wording and density automatically switch to chorus-flavored when a chorus section is selected. Multiple Export Formats Export to .flowysheet, MusicXML, MIDI, and WAV. MIDI supports mid-song time-signature changes; MusicXML emits full start/stop notation for hammer-on / pull-off / slide / glissando / tie — drop straight into your DAW or score editor. Flowy Companion App Generate wide-scroll TAB images (.flowysheet) for smooth playback in the sister app Flowy. Measures-per-page and page/sec are configurable on the export screen. Playability Filter Every pass runs through an automatic playability check — fret stretch, string collisions, position warps are all reined in so the output stays within reach for beginners. Apple Pencil Support (iPad) Handwrite fret numbers directly on the TAB grid. Emotion Map & Analysis Visualize brightness and energy per measure or section. Drag a destination on the map and FlowySheet suggests arrangement candidates that move you toward it. 【Fully Free】 Every feature is free. No subscriptions, no in-app feature unlocks, no ads. An optional Tip Jar lets you support development if you like the app — tips unlock nothing extra. 【Best For】 • Guitarists writing original fingerstyle solos • Players arranging existing songs in their own voice • Adding a memorable chorus highlight • Bridging into DAW / score-editor workflows via MIDI / MusicXML • Practicing with the Flowy companion app

Verdict
The clearest difference is update cadence: FlowySheet at every 5 days against I's every 5 months. I's advantage is iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
