Every guitar practice tool is included: tuner, metronome, chord handbook, and a personal songbook. No subscription, no account, and no catalog paywall. OpenString is built for guitarists who want the tools on their phone, not a rented song library. Install it from the App Store. You get the tuner, metronome, chords, and songbook. There is nothing left to unlock later. WHAT YOU GET Guitar tuner Tune a standard six-string guitar with the microphone. Choose a preset, let the app pick the string or choose it yourself, and play a reference note when you want a target pitch. Audio is processed on your iPhone. It is never recorded or uploaded. Metronome Keep time from 40 to 240 BPM. Tap a tempo, set the meter, choose subdivisions and accents, run a practice timer, or mute the click and follow the beat visually. Chord handbook Look up common major, minor, and seventh fingerings in standard guitar tuning. Search the handbook, save favorites, hear a reference voicing, and jump to alternate positions on the neck. Personal songbook Keep your own lyrics and chords. Transpose the displayed key and save a capo preference without rewriting the source chart. Add song metadata, build named setlists, practice with autoscroll, jump to chords used in a song, and import ChordPro. Create and edit on your phone, then export a backup to a destination you choose and restore it later. Song to chords Pick a song and get its chords and words together in one tap, ready to play and sing. Scale and shape finder Type a scale like A minor pentatonic and see its box shapes on the neck, with the fret positions you actually play them in. HOW THIS IS DIFFERENT There are no in-app purchases and no subscription. Every current tool is included with the app. The tuner, metronome, chord handbook, and songbook are not split across plans. No commercial song catalog is included. Your songbook is filled by you, whether you type it or import ChordPro. That is the point: your charts, your lyrics, your practice. The app works offline and needs no account. No feed. No ads in the app. WHO IT IS FOR Players who want a tuner, metronome, chord diagrams, and their own charts in one place. People who write songs, type lyrics and chords they already play, or import ChordPro. WHO IT IS NOT FOR OpenString does not rent you a library of popular songs or official tabs. If you want a commercial catalog behind a monthly plan, this is not that app. OpenString is built for guitar practice on iPhone. ## Key features - Guitar tuner - Metronome with tempo and meter settings - Chord handbook with fingerings and voicings - Personal songbook for lyrics and chords - Key transposition and capo preference - Scale and shape finder ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | OpenString Pro | $9.99 | one-time | ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/openstring-tuner-and-chords/id6811273833/reviews.md ### 5/5 — Incredible and useful thank you *2026-09-18* It's nice to have a simple interface that just works without all the annoying things Also the recording to detecting a song is amazing and awesome really cool ## Frequently asked questions about OpenString ### What tools does OpenString offer for guitar practice?

Every lesson gives you 1 to 3 stars and XP, and your level climbs as you play. Missed the third star? The result tells you exactly what it takes. Practice 5 minutes a day. A ring fills as you play, three goals wait for you each day, and a week of practice earns a streak freeze that covers a missed day. Timed note lessons now slide the notes toward you. Build a combo, see whether each note was early or late, and race the ghost of your best run. Play it clean and the next run is 5 BPM faster. Your lessons sit on a path, so you can see how far you've come. Pass one and share your score as a picture. New sounds and taps you can feel, both with an off switch in Settings. Everything still works offline, with no account. ### 1.7.0 — 2026-09-29 Learn guitar with a coach that listens. The new Learn tab is a 72-lesson course in three levels. Beginner: your first chords, more open chords and strumming patterns. Intermediate: barre chords, riffs and power chords, fingerpicking. Pro: lead guitar with the pentatonic scale, bends, hammer-ons and slides; color chords; and the whole neck. Play along and OpenString hears every strum and note. It tells you which string was muted, which note was off, and whether you were on the beat. Every lesson works offline, with no account. ### 1.6.3 — 2026-09-28 Naming a song is more reliable. A listen that fails no longer spoils the next one, and when a song cannot be named, OpenString tells you what to try: play it from a speaker nearby, or type the title. ### 1.6.2 — 2026-09-27 Slash chords now open properly: tap G/B in a song and you get its diagram, with the full name G/B on the sheet. ### 1.6.1 — 2026-09-26 Crash reporting is now enabled to help us identify and fix crashes. ## Apps similar to OpenString | App | Rating | Price | Category | | --- | --- | --- | --- | | [YAGT: Guitar & Bass Tuner](https://appshunter.io/ios/app/yagt-guitar-and-bass-tuner/id6762066678) | 5.0 (2) | Free | Music | | [Offline Music Player By VP](https://appshunter.io/ios/app/offline-music-player-by-vp/id6741097289) | 5.0 (1) | Free | Music | | [Fretride: Learn Guitar & Jam](https://appshunter.io/ios/app/fretride-learn-guitar-and-jam/id6792441975) | — | Free | Music | | [iontuner](https://appshunter.io/ios/app/iontuner/id6767259524) | — | Free | Music | | [All Kenya Radio Stations Live](https://appshunter.io/ios/app/all-kenya-radio-stations-live/id1225133956) | 4.3 (93) | Free | Music | | [JamTracks+ Learn & Play Guitar](https://appshunter.io/ios/app/jamtracks-plus-learn-and-play-guitar/id436102935) | 4.5 (757) | Free | Music | ## More apps by Techguyver Labs, LLC - [MightyMouse: Build With AI](https://appshunter.io/ios/app/mightymouse-build-with-ai/id6796192096) - [GoKuna](https://appshunter.io/ios/app/gokuna/id6812677704) All apps by Techguyver Labs, LLC: https://appshunter.io/developer/6796192098 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
