Read full description

Never wonder when you last changed your strings again. StringKeeper helps guitarists track string installations across every guitar in their collection, so your instrument always sounds its best. Track Every Guitar: Add all your guitars with photos, names, and notes. See at a glance which ones are due for a string change and which were recently restrung. Log String Changes: Record the string brand, gauge, and date every time you restring. StringKeeper tracks your history so you can see what worked and what didn't. Get Reminded: Set a reminder after a string change and StringKeeper will notify you when it's time to restring — no more playing on dead strings. Log Play Sessions & Maintenance: Track how often you play each guitar and log maintenance records to keep a full history of each instrument. If you notice a guitar has dead strings you can set a "Needs string change" flag which will cause an alert icon to appear next to the guitar. Pick a Guitar to Play: Not sure which guitar to pick up tonight? Use the slot machine to let StringKeeper choose for you.
