I've just checked your app and it's not even ranked for "workout tracker", " gym logger" etc. You're losing a lot of organic visibility from the App Store. If I were you I'd look into an experienced ASO specialist to level up your app store game, for example, @nickjsheriff (Twitter).
Also, $80-120/h for the iOS dev hour is a lot, I assume you hire in the US?
