Great idea. Repeating technical issues.
I do not recommend this app for the push-up challenge. It missed three out of my 15 days. Have a modern phone, great Internet, etc. —- When efforts in a challenge are mistakenly not identified, it’s disheartening. No response from the support team as to why the push-up efforts were intermittently no recorded. My understanding is that some type of AI is used to verify if the push-ups are valid. I expect the problem is in that step of the verification process.
