Whether you are a recreational player or a pro, tracking your frames, string jobs, and playing hours has never been this beautiful or professional. The real revolution: Tension Lab. Ever wondered if your strings have lost tension and need to be cut? Thanks to our new advanced acoustic algorithm, just make your string bed "ping" near your iPhone's microphone.

Read full description

Your strings change every time you play. Tennis Tension Lab helps you see that change before it surprises you on court. Place your phone beside the racquet and tap the center of the string bed three to five times. The app analyzes the sound on your device and gives you a repeatable tension estimate in seconds. KEEP YOUR SETUP CLEAR • Check current string tension • Compare each reading with the baseline from a fresh string job • Follow tension loss on a simple timeline • See when it may be time to restring • Keep every racquet, string job, hybrid setup and note together • Find models quickly in a catalog of 1,347 racquets and 216 strings • Compare string characteristics before choosing your next setup MADE FOR THE COURT No account is required to start. Tap audio is analyzed in memory and discarded; only measurement results are saved. Choose lb or kg and keep your history organized by racquet. For the most consistent results, measure the same racquet in a quiet place with the same tapping method. Readings are estimates based on sound and equipment information, not certified measurements from a stringing machine.
