I’ve always wanted something like this, so I’m happy to have it (even bought premium), but some stuff doesn’t work. Whenever I open up “Customize Fitness AI” or “Stress Management” or something, it immediately closes out. Wish I knew this before paying a year’s premium, I thought it was only closing out because I had the free version.
Developer Response
Hi there, Thank you for getting ftnss and I’m very sorry you have this problem, it should not be happening. I tested this with multiple devices and I cannot reproduce the problem. If you’re keen to send me an email to cristianrus@hey.com with more details, I can help you through to fix it and be able to use properly the app. Looking forward to hear from you. Thanks.
