I wanted to tune my guitar to Esus2 open to play a John Mayer song. Nothing I owned had it, so I built this. You choose the tuning, then play. It figures out which string you're on. A string that's way out can read close to two targets at once. Most tuners re-pick every frame and jump between them while you're turning. This one holds the string it picked until another is 40 cents closer. Free: eleven tunings, chromatic mode, calibration, string lock. $4.99 once: the editor for building your own, the metronome, iCloud sync. It's iPhone only: one string at a time, no chords, no lessons. No account, no ads. I keep going back and forth on the paywall. In 2.1, I moved standard bass and ukulele out of Pro, because charging for a standard tuning felt wrong. The editor is still paid. Should one custom tuning be free, so you can build the tuning you came for and hit the limit on the second? Or is a capped free tier worse than a clean paid one?
