Very useful. I just tried it with my spare racquet, and it seems about right. I have always wondered if my main racquet has lost tension, so it'll be really useful for that.

For making money, I'd suggest reaching out to professional re-stringers and asking if they want to advertise (once you have some nice analytics to brag about). Maybe even localise them based on geolocation data so you can have more re-stringers without cluttering it up. It's a value-add to your users so everyone should be happy.

You could probably even reach out to some YouTubers (I personally like BadmintonInsight). Since it's free, I would imagine some of them would do a video on it just to help their viewers.

Finding stringers nearby is really cool idea. Yeah, BadmintonInsight is a really good channel. I'll try reaching out.
