- 📦String Tension AI: Tennis updated to version 2.37String Tension AI 2.37, the best iOS tennis racquet and string-tension tracking app on the market, makes Top Strings For You more useful with clearer match scores, individual string ratings, racquet-pattern guidance, and labels for strings you already use and tour-player usage. With PRO, the full recommendations list adds suggested starting tensions, tension-retention comparisons when supported by your measurements, and a Budget-friendly only filter.
Match scores no longer depend on which other strings are shown. The Strings-tab preview uses your playstyle and string ratings; the full list also considers your measured string history. My Strings, Wishlist, and String Comparison recognise alternate string names more reliably, including their usage and cost history. Calibration handles equipment corrections more consistently, Smart Detection reduces false alerts from noisy readings, and Reset All Data adds safeguards when switching iCloud accounts.
App Store Release Notes:
- Clearer match scores reflect how well a string suits you, without changing just because other strings are shown. Equally suitable strings keep a consistent order.
- Strings you already use are marked "In your bag" or "Used before", and you can see how many tour players use a recommended string.
- Recommendations know more about each string: popular strings now have their own comfort, spin, durability, power, control, and feel ratings, so similar strings are told apart.
- Recommendations now consider your racquet's string pattern: an open pattern favours strings that last, and a dense pattern favours softer, livelier strings.
- PRO: each top string pick now comes with a suggested starting tension for your main racquet.
- PRO: when your measurements show your current string losing tension, recommendations point out strings that hold tension better.
- PRO: recommended strings show a price band, and a "Budget-friendly only" filter keeps the list to budget and mid-range strings, with a reminder when you are close to your string budget. The reminder reflects string-cost changes received through iCloud.
- The Strings-tab PRO preview follows the budget-friendly filter too, with a clear message when no string matches it.
- Correcting a restring's date keeps historical play on the strings recorded in use that day. Gauge corrections are handled more accurately in Smart Detection for older string setups.
- Recommendations and String Comparison stay consistent when string jobs have identical dates.
- A string saved under another of its names (such as Babolat RPM Rough for RPM Blast Rough) is recognised as the same string: it shows "In your bag", and with PRO your ratings and measurements of it count towards its recommendation.
- My Strings and Wishlist also recognise alternate names, including Hyper-G Heaven for Hyper-G. Recording those strings marks an existing wishlist entry as tried without adding a duplicate.
- Wishlist browsing is more responsive, and library labels stay current after iCloud changes or recording new strings.
- My Strings includes usage, costs, gauges, and last-used dates for string jobs saved under alternate names. String Comparison includes those jobs' costs and measured tension retention too.
- Wishlist reminders stay current when another device marks a string as tried.
- Smart Detection reduces false new-string and sudden-loss alerts from noisy readings, and a noisy follow-up no longer dismisses a valid new-string prompt on the Dashboard.
- If deleting a playing session fails, Session Details stays open with your typed notes.
- Correcting a racquet's head size, or string gauge or material before the first saved reading, preserves calibration where possible. An incompatible calibration is cleared for recalibration.
- Added safeguards for Reset All Data when switching iCloud accounts.… more - 📦String Tension AI: Tennis updated to version 2.36String Tension AI 2.36, the iOS tennis racket and string-tension tracking app, makes Tension Advisor more useful when planning your next restring.
With PRO, try a different string material, gauge or swing speed in What-If, and see how each choice changes the advice. When you open a new string setup from the advisor, the recommendation updates for the strings you enter, with Apply, Undo and an optional hybrid split suggestion.
Your playstyle profile can now describe the climate where you usually play. When needed, Tension Advisor asks whether your current tension was chosen for your game or suggested by the shop, helping it avoid adjusting for the same preferences twice. Advice also balances combined adjustments more carefully and makes better use of playing intensity and measured tension loss. Calibration changes and equipment corrections are handled more consistently, readings keep the time they were taken, and historical play is assigned more accurately. Existing data is preserved during a normal upgrade; optional analytics continue to require consent.
App Store Release Notes
- With PRO, explore different string materials, gauges and swing speeds in What-If, alongside the existing court, weather, arm-comfort and priority choices.
- See the individual effect of each What-If choice and the combined recommended tension.
- When starting a string setup from Tension Advisor, advice updates for the strings you enter. Your manual tension edits are respected, with Apply and Undo controls for the advice.
- Two-material hybrid setups can offer an optional lower-crosses split while keeping the overall tension close to the recommendation.
- Add your usual playing climate to your playstyle profile, so tension advice reflects where you play. Leave it unspecified to use the conditions recorded with your measurements.
- When needed, Tension Advisor asks whether your current tension is already tuned for you or is a shop default. Confidence better reflects how much is known about that starting point.
- More balanced advice accounts for playing intensity and separates early string settling from ongoing tension loss. Light play no longer lowers the advice simply because you play less often.
- Clearer material-switch explanations and improved layouts on smaller screens.
- Calibration now offers I've Restrung Since Then when the recorded strings are out of date, so you can record the new strings before calibrating them.
- Smart Detection better distinguishes calibration and equipment corrections from real changes in your strings. Measurement comparisons avoid treating those corrections as tension loss.
- Readings saved later keep the time they were taken, including their baseline eligibility, and remain eligible for iCloud sync.
- Log past play on retired strings, including Apple Health workouts, while the racket awaits a restring. Days with no recorded strings are explained, and corrected restring dates keep
playing history aligned.
- More reliable sharing and notification handling, plus clearer string-budget forecasts and alerts.… more - 📦String Tension AI: Tennis: now updating weekly4 updates in 30 days, after a quiet two months

- 📦String Tension AI: Tennis updated to version 2.34String Tension AI 2.34 makes it easier to keep track of the people who string your racquets. Open My Stringers directly from the Strings hub to manage contacts, favorites and restring history, whether you use Free or PRO. A stringer's Annual Summary, including PDF export, now requires PRO, with clearer access and export progress.
The How to Measure video has refreshed English narration with more even volume between lines. Dashboard figures, racquet health, Compare Racquets and Tension Advisor guidance stay current when the reliability of a saved reading changes. Stringer screens handle records removed through iCloud sync more safely, and clearer delete guidance helps you preserve stringer history. Existing data is preserved during a normal upgrade; optional analytics continue to require consent.
App Store Release Notes
- Open My Stringers directly from the Strings hub. Manage contacts, favorites and restring history with Free or PRO.
- Review a stringer's year with Annual Summary and export it as a PDF with PRO. Export progress helps prevent repeated taps from opening duplicate reports.
- Refreshed English narration, new German, Italian, Spanish, French, Danish, Brazilian Portuguese and Simplified Chinese narration and more consistent voice volume make How to Measure easier to follow.
- Dashboard figures, racquet health, Compare Racquets and Tension Advisor guidance update more reliably when a saved reading's reliability changes.

- 📦String Tension AI: Tennis version 2.32String Tension AI 2.32 gives users of the #1 iOS tennis racquet and string-tension tracking app a narrated How to Measure video with localized captions, more accurate string-job history, and clearer spending by currency. Apple Health import review remains free on supported devices, while automatic import remains a PRO feature. The Tension Advisor now keeps recommendations consistent across restrings; personalized advice continues to require PRO.
Calibration and tension forecasts handle changes in the calibration used for a set of strings, and Apple Health sessions that may duplicate a manual log are easier to review. Exports, reminders, purchase restore, recovery and iCloud sync are more reliable. Existing data is preserved during a normal upgrade; the release includes a lightweight local data migration and already deployed iCloud schema additions. Optional diagnostics continue to respect analytics consent.
App Store Release Notes
- Learn to measure with the narrated How to Measure video, localized captions, playback controls and Skip.
- Past string jobs imported from Apple Health stay in history without replacing current strings; backdated restrings assign playing sessions to the strings used on those days.
- Tension Advisor recommendations no longer drift just because you followed earlier advice and restrung again. Split-tension setups apply the suggested change to both sides.
- Calibration and forecasts use readings from the current calibration; older strings ask you to enter a current reference tension.
- Spending and comparisons keep different currencies separate. Cost per day uses completed string jobs with recorded prices.
- Possible duplicate Apple Health sessions are flagged for review, and automatic import resumes more reliably after PRO is renewed.
- CSV and PDF reports are easier to use, with clearer split tensions, improved racquet QR links and better spreadsheet compatibility.
- Restore Purchases shows progress and a clear result. Reminders, backups and iCloud sync are more reliable, and measuring stays responsive while the microphone starts.… more - 🆕String Tension AI: Tennis released on the App Store
