Fretride vs Soundslice

Fretride is a guitar practice and songwriting app for iOS and macOS, with a fretboard visualizer, playback engine, tab editor, pattern library, lessons, and practice games. The fretboard displays notes by key and scale degree, plays notes, and shows chord shapes across the neck. Its touch-focused editor handles full songs and techniques including hammer-ons, pull-offs, slides, bends, palm mutes, and triplets. With an audio interface, the app scores timing and selected playing details; analysis runs on-device and microphone audio is not recorded, stored, or transmitted. Lessons and games are included in the free version, which allows up to three saved songs and needs no account. The app includes hand-recorded guitar samples and separate tracks for drums, piano, bass, violin, cello, flute, saxophone, and trumpet. Signed-in Pro users can sync songs, tabs, progressions, patterns, and lesson progress across devices. Pro also adds unlimited saved songs, custom arpeggio and strum patterns, additional guitar tones, and MIDI instrument sound banks. Monthly and yearly subscriptions are billed through Apple, with exact regional prices shown in the app before purchase.

Soundslice combines sheet music, audio, and video in an interactive player for music practice, teaching, and transcription. Practice tools include tempo changes that preserve pitch, looping, part muting, transposition, speed training, and a metronome with count-in. Its web-based notation and tab editor supports creating scores from scratch and editing imported ones, with basic use available for free. Users can import MusicXML and Guitar Pro files or scan sheet music from PDFs and photos, subject to plan limits. Notation can be synced with YouTube, uploaded MP3s or video, and supported Vimeo or Wistia videos, depending on plan. Teacher supports private courses, student performances, and private feedback, with 100 students included. Licensing lets organizations embed the player in a site or app. The Free plan includes unlimited slices and two scan pages monthly, limited to one page and 32 bars per scan. Plus costs $5 a month, billed at 5 USD monthly or 50 USD yearly, and includes 100 scan pages monthly. Soundslice is available on Android, iOS, and the web.
