Great gym tool

I’ve been using Strong for a few months now and it’s great! I’ve got it on my iPhone and Apple Watch which is handy during workouts as you can just use the watch and add your workout as you go along
I’ve only got the free version and won’t be getting the pro version anytime soon due to the huge price tag.
There are a few negatives to this app though. It drains your battery, big time! I’ll go in with 80% and come out with 20% after an hour or 2 working out! If you put your phone on airline mode though it only uses a fraction of that which is strange. It is definitely this app draining the battery as I only have this running during training.
Also, if you are using the Apple Watch app and adding your workout as you go, you can add an exercise but it only adds one set, you can’t just add a few sets for each exercise like you can do in the phone app.
I’ll keep using this app as it’s brilliant and could easily get 5* if the above is sorted. Also if the pro version was around the £5 or under mark I would buy it but otherwise I’ll just stick with the free version

New UI is bad compared to previous version

The previous version was perfect: it was easy to set the difference for rest times (now it seems to have remembered all my rest times incorrectly), in the rest timer, it would tell me what’s next (I’m not an idiot, but it was nice to see what was next especially when I’m a bit “WOO YEAH HEAVY” after a good squat)’s the rest timer I have the biggest issue with. Also, it says that I’m making new PRs...then doesn’t show me what ones it means? It did before. This is strange because I feel like I’m not making any PRs, so I’m confused as to what they are, especially when it isn’t specific on what lift it was. New UI design is very nice though, some issues with the keyboard not disappearing as fluidly as the previous version, but all in all, aesthetically quite pleasing. Love this app so pretty sure stuff will be sorted, but thought it was fine before! UI changes bring some bugs I guess though, so thanks for doing your best, peeps!

Hey Matt! Thanks for all these insights. Most of the feedback we have received from the new version thus far has been positive and we try our hardest to keep everyone happy. However, the rest timer and the display of PR's has been brought to our attention by other users as well and we intend to make changes to these features to utilize their full potential in the app in the future. We appreciate you sharing these thoughts with us and I will be sure to share this with the team so we can keep it in mind for future updates. Feel free to also reach us at Happy Lifting! -Strong Team

One of the best weight tracking apps out there!

This app can give you what many of the others struggle with:
- an easy display yet looks good, to set up workouts and records your weights and sets.
- The feature to add in dropsets/failure sets/warmup sets is something not a lot of the other apps have and I must say this is a nice addition!
- the ability to be able to switch tabs and see your history and progress charts at a glance mid workout is brilliant.
- this app is perfect for someone who just wants to set up their routine, record their progress and get on with it.

- the price: surely you’d have so many more subscribers if you just dropped this to a reasonable level in line with the rest of the market?
This is a great app because you haven’t overcomplicated or crammed in too many unneeded features like your competitors. No sensible person is going to pay £100 for an app to record weights and sets.
- Are you build in -/+ weights for weighted assistance exercises so one can go from assisted to weighted and still track their progress?
- The charts & progress graphs could do with a bit of development, look very basic. (For the price you’re asking for you should have the best analytics out there)

This is a great app overall.
