What people are saying:

"As a lifelong fitness enthusiast, I’ve been promised many times a “virtual personal trainer” using the technology in my smartphone but Optimize Fitness is the first app to actually deliver on this promise. An app that understands that real life training happens at different gyms, with different amounts of time to work out and when I’m feeling different energy levels. After trying most of what else is out there on the market, I can say, without equivocation, Optimize Fitness is the best fitness app for REAL people with REAL lives and REAL fitness goals"

"I love not having to think about how many reps I need to do, how much weight to use and when to increase! Optimize learns my fitness level and does it all for me!"

"Being able to easily substitute exercises in my workout is great; I injured my shoulder and can’t do kettlebell swings anymore."

"I feel energized after working out with Optimize. It knows what I want to accomplish and adjusts the routines to push me to get there at my pace. I love that I can use it anywhere I am traveling, with or without a gym and still get a solid workout."

Eliminates the need for a personal trainer

I always hated paying for a personal trainer. They're expensive and make me uncomfortable. Optimize Fitness gives me confidence in the gym through detailed workout instructions and as a fitness tracker. This fitness app is great whether you want to lose weigh, gain muscle, train harder or just get the perfect summer body. The AI (artificial intelligence) algorithm always keeps thing. Definitely my favorite fitness app

Was good while it lasted

I’ve used this app for over the year, and I’ve appreciated the quality of life updates over that time.

But now for some reason the app keeps crashing before I can get a workout together. Whether it’s because of an update or my aging phone I don’t know, but I don’t have the time/patience to troubleshoot it.

When the app is functioning as intended it’s pretty useful for those just starting out who need a good jumping off point when planning workouts, so if that sounds like you and have enough hardware under the hood to handle the seemingly resource-heavy current version, by all means knock yourself out.

Amazing App, Too many bugs, Could be 5 + stars!

This is the type of fitness app I have been searching for - for a very long time. I’ve gone through 20+ apps before I came across this one. It was perfect for what I wanted. However, it’s difficult to use sometimes because it freezes and crashes & changes the reps when it is time for a workout. But I’ve been working around this. However, yesterday I noticed when creating a new workout, it won’t add any custom exercises into the workout. Only the pre-populated ones. So I cannot create the workout needed to add to a plan.
