RacketSlate

RacketSlate is a private, offline racquet string-bed and play-session ledger for iPhone and iPad. Keep dependable records for tennis, badminton, squash, padel, and pickleball without an account, subscription, advertising, analytics, tracking, cloud dependency, or required internet connection.

• Catalog multiple racquets with sport, model, status, notes, and a clear current setup
• Record full or hybrid string beds with mains, crosses, gauge, tension, unit, stringer, date, cost, and feel
• Log practice or match sessions while permanently linking each entry to the string bed used at the time
• Close string beds as broken, cut out, replaced, or retired, with optional final tension and notes
• Correct, void, or restore records through an append-only audit trail that preserves the original entry
• Review factual 30-day, 90-day, or all-time summaries without equipment or medical recommendations
• Search and filter your ledger, export readable text or RFC 4180 CSV, and create checksum-verified backups with preview, merge, replace, rollback, and recovery

Your racquets, string beds, sessions, closures, revisions, exports, and backups stay on your device unless you explicitly export them. Optional feedback sends only the message, contact email, diagnostics, and screenshots you choose—not your racquet ledger.
