Purchase Frettly
Unlock Frettly Pro as a one-time purchase on the Mac App Store and get ongoing updates to existing features — bug fixes, performance improvements, and refinements — at no extra cost. No monthly or annual subscriptions, just a one-off purchase, with Family Sharing enabled.
Why Go Pro?
Frettly started life as a personal project to help understand the guitar through clear visualisation, interactivity and application of music theory. Frettly Pro is the document-based realisation of that desire, allowing you to save multiple scale/chord/mode fretboards within individual documents — built for players who want to explore scales, chords and tunings with flexible features and interactive audio.
When you go Pro, you’re getting more than just the current feature set — you’re also supporting ongoing development and helping to shape where Frettly goes next.
What You Get with Frettly Pro
- Access to the full Pro feature set available today.
- All current instrument tunings, plus future tuning additions.
- Create fretboards with the full catalogue of 14 Scale types, 9 Modes, and 44 Chord types — with more added over time.
- Bug fixes, performance improvements, and refinements to existing features.
- Ongoing refinements based on real user feedback.
There are no subscriptions — just a straightforward, one-time purchase on the Mac App Store.
Occasionally, substantial new modules may be available separately. If that happens, they’ll be clearly labelled and entirely optional — you’ll always keep what you’ve already unlocked.
