For coaches

This app is for coaches and gyms. Can be useful for an individual IF they already know exactly what theyre doing as far as fitness. Its coaching software

Too buggy

I’ve been trying to get into the app to do my workout for the past 20 minutes. All it does is load and crash.

Only One Major Flaw

Great functionality, does a lot of things right. The fact that it is cloud-based is unbelievably aggravating. I am begging you to let me download my training block and store it on my phone. I spend an egregious amount of tome waiting for the app to load when I am training somewhere with less-than-ideal reception. It’s a small problem but it has made me stop using the app while actually training - instead I have to get my block and write the whole thing down before training

Horribly slow

This app doesn’t run in the background and reloads every time you switch apps. Additionally, the loading time is terribly slow (why is there a loading screen for an iOS app in 2026??), which you have to sit through any time you switch apps.

Some issues

The developers refuse to get the timer working properly and the app will send multiple notifications telling me to GET BACK TO TRAINING!! after I have confirmed my workout is complete. It’s a good app and could be a great app one day.

Buggy

This app is atrocious, freezes once a session at least when trying to add workout data or videos and now the app won’t let me log in at all. Website unusable as well.

Incredibly frustrating

This app is good to keep everything in one place for coaching but it doesn’t upload properly from my fitness pal, either incorrect details and calories / sometimes not at all. I constantly have to reinstall due to it freezing.

The app is good

I’ve been using the app for a while now, at least a year if not more, and, while there have been some hiccups here and there, the app has been great. Any issue I’ve had to the dev team fixes it with a day or two too, and that’s if an update didn’t fix it. The new design of the UI has been nice too!

Timer is a big ask

Almost everything is great. Getting the timer function to work like an actual timer (making a sound while in the app) is a big ask for the team. Otherwise, would have been 5 stars.

Not there yet

Very very buggy when it comes to entering the weights, or log in a set. Just bad to use. Sometime it doesn't remember or will log without me pushing the "done" button. Very frustrating.

My kingdom for an offline mode

Update: downgrading this to one star because where did my calendar go? Why do I have to scroll through the entire month to get to July 30!? This thing is always broken and so it’s not even showing me today is anything other than a rest day , but if I open calendar and scroll all the way down to July 30 I can get training info. Are you kidding me?

I lift in a gym basement. Great equipment, terrible signal, no WiFi. This app is almost unusable. It glitches and crashes without WiFi. I have to track my workout in Strong and update it here for my coach later. This app is worse than split squats.

Insanely buggy

Been using it for over a year at my trainers insistence. I never make it through a workout with it crashing a few times. When it doesn’t crash it’s buggy and slow. I don’t know what the competitors in this space are like but I can say that this thing is infuriating to use.

Reviews about it being buggy go back years, so guess what they’re not working on?

App itself very good, integrations could use work

The app itself works really well. No issues for me, loads fine, data input it fine, receives programs from coach no problem. Took a star off because the apple health integration refuses to stay connected no matter what I do. Every day I have to reconnect this app to apple health so my sleep/macros/calories will populate. Would love to see this fixed!

Always improving

It seems that most reviews of this app are old and negative, and I’d like to add a current one. This app is great. Fully customizable, tons of cool built in features, and better support than most apps in this niche. I put off switching from TrainHeroic for years, and having made the switch I couldn’t be happier with the more rich featureset on mystrengthbook. I recommend this app to any coach looking for a high quality training app

Plagued w/ bugs

Extremely buggy where by reps & weight won’t save properly. It’s a known issue amongst coaches signing clients up on the app. For the price paid it’s very clunky for our clients.

We’ve had to ask clients to manually note down their weights & reps as it’s too buggy.

Bugs and glitches and inconvenient

Why is there not a version of the app for coaches, how does that make sense?

I have to log on through a web browser and 1/3 of the time it won’t let me get past the login page. Just says it’s loading for ~5 minutes and then nothing happens.

Useless for an individual

I was looking around for a strength training tracker/planner that isn't bogged down with microtransactions and all that junk. Just be warned, don't glance too quickly over the description. This isn't an application you can use as an individual. It requires someone else to pay a subscription so you can use it, or something. I don't know. It's not 100% clear their whole setup. So, for most people just looking for tools to help them, this wont help ya.
