StringTracker vs Racketeer

StringTracker helps tennis players keep track of racket string life with a simple, focused workflow. Add your rackets, record when they were last strung, and update playtime after each session. StringTracker keeps a clear running total of hours played on each string job, so you can decide when it is time to restring based on your own playing habits. Track multiple rackets: Keep all your rackets in one place and see their current string age at a glance. Log playtime quickly: Add or subtract playtime with simple swipe actions using your preferred time increment. Set your restring target: Choose the number of play hours you consider optimal before restringing. Mark rackets as restrung: Reset playtime when you restring a racket while keeping your tracking simple. Organize your list: Rename, reorder, or remove rackets as your setup changes. StringTracker is built for players who want a lightweight way to manage racket maintenance without spreadsheets, notes, or complicated session logs.
