Measure badminton string tension with your iPhone. SweetSpot listens to the sound of your racket strings and estimates tension from the vibration frequency. It helps you check a fresh restring, compare rackets, and see when your strings are starting to lose their feel. Why players use SweetSpot: • Estimate string tension in seconds • Track tension history for each racket • Save racket profiles with string gauge and head shape • Compare readings after restrings and between sessions • Get guided tap detection for cleaner measurements • No separate tension meter required Built for badminton players, coaches, and stringers who want a quick way to monitor racket setup. For best results, measure in a quiet room, use the correct string gauge, and compare readings over time on the same racket.
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 7 screenshots above are SweetSpot: Racket Tension's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: SweetSpot: Racket Tension runs a dark set with one background colour (#040404) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #0C84FC, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
