The best thing about this app is that it helps me keep track of all my data which makes running programs easier than ever! I have never used an application like fit manager before but from what i've read, its very customizable if you know how things work in different platforms (CAD for example). If there's one negative aspect then maybe having multiple accounts at once could be improved upon so each account has their own way they want everything displayed. But overall positive experience with them as well!! This tool gives us much more freedom when creating courses since we can use many exercises without limitations unlike other applications where only few are allowed by creators themselves.
