Sizing and comparison issues

Three issues - 1 - data and screens get clipped when viewing on phone so can’t see all info. Nothing I can do to fix this and very frustrating. 2 - requested to be compared to a female player and always compared to a male player (usually Jannik, i wish i was a 6’4” male pro player, i am not). 3 - if I reverse the camera to shoot my serve the AI somehow puts the racquet in my LEFT hand and treats me like a lefty. It’s bizarre.

Too EXPENSIVE

Looks like a super interesting app and was excited to see how well the model was trained. However I realised just as I went to use the ai model that it is too expensive!! $49/ month is way too much money when I had no idea if the model will even work.
Giving it 2 stars instead of 1 tho because I’m interested by this and hope it’ll grow into something more available to everyone!

zu teuer!

viel zu teuer! schade weil an sich eine gute idee. 350€ nur für aufschlag ist zu viel. das muss auch günstiger gehen vielleicht mit werbung ansonsten buche ich mir einfach einen trainer und hab für weniger geld mehr davon.

300$ per year paywall

This buggy app which doesn’t work is behind a 300$ dollar per year subscription. Insanely steep price for something that doesn’t help your game at all. Much less worth 30 dollars a month. Feels like a rush job. There are definitely better alternatives to this.

The worse part is the AI ‘support’

Uploaded a video of my serve to the app, and the feedback I got was ‘no mistakes’.

The support team consists of an AI robot waffling on about general issues. It’s told me to add better prompts ‘comparing it to top pros’, (fairly sure there is no option to add prompts) ‘take a side shot for more accurate analysis’ (a direct contradiction to the instructions). ‘The app is probably analysing general flow and not biomechanics’.

The app is also really clunky and slow.

Don’t trust these slick YouTube videos. So far it’s been a complete waste of money.
