This app is probably the best lifting log out there
I’ve been using it almost since day one, back when it was focused purely on 5/3/1. Since then, it's evolved into something even more powerful and flexible. What really speaks to me is how it keeps that clean, intuitive interface and that cult-classic “BigLifts2” vibe. What sets this app apart is how it adapts to you - the customization and the thoughtfulness behind every screen. It's obvious this is built by someone who actually lifts. So a huge shout-out to Jimmy C., the developer, who was kind enough to extend my Pro year when I reached out through Support, since my country is currently cut off from App Store payments. I was really surprised this app has so few ratings - it definitely deserves more recognition for its user-first approach. Highly recommended!

Great App for 531 and more
I’ve had this app for quite some time. I’m extremely happy with the lifetime subscription purchase. This app has been so useful. There’s many little additions that make it top tier. Also if you learn and understand the app, there’s so many possibilities for creating your own program.
I highly recommend KeyLifts, even if you’re on the fence with 531, due to the possibilities of program building.
Last great point is to this day the app is continuously being updated. I just submitted a ticket for a bug and had an email back in less than an hour.
Highly highly recommend! Buy the subscription too and the lifetime if available. It’s more than worth it!!!

Essential of 5/3/1
Fantastic and powerful app! Having the level of tracking has helped me, an advanced intermediate, finally get over certain strength humps. It doesn’t look incredibly sexy, but neither does Excel and we all know how powerful that tool is.
Great
Good app. Does everything i want in an app well. Has the right programs and ease of changing things to suit is awesome. Plus i reported a bug and it was sorted within 24 hours. Nice
Such a great app
Used it for the trial and bought the lifetime subscription straight after. The only app that fit exactly what I was after and is continuously being improved, thanks Jimmy!
Best Lifting App Period
Look no further. Has everything you could ask for and endless customization. Dev is extremely helpful and responsive, fixes any bugs that pop up quickly. No more spreadsheets and logbooks, just enter everything right on your phone.
Incredible App for tracking numbers
Best workout app I’ve ever used. It’s constantly being updated with new features and UI improvements. Easy to add your own routines and exercises, and tracks everything. This is the only app I’ve ever felt a need to review because it’s that good at what it does.
2025 FERRARI OF 5/3/1!
You have never seen anything like this before! The inexplicable amount of time invested into this work of “software art”, and the unmistakable passion for the 5/3/1 philosophy become obvious as soon as you open the app! That alone justifies the price of the subscription in a heartbeat! Silky smooth, intuitive and outstandingly reliable- the app is a “delicious” bite from the App Store’s kitchen! The meticulously structured 110 templates would make Jim Wendler happy! Everything works: counts, combines, remembers! A few years ago, when the app was a little baby 👶 , making the first timid steps, some impatient, unhappy people left the undeserved one-Star reviews! Today, a Super-Smart Kid, the App will show a stunning performance that is Superior to any competition! Do you want the Encyclopedia of 5/3/1 in your pocket? Do you want to experience the sensational support from the developer? Then- go for it! You will not be disappointed! To the Developers: Extremely well done! Outstanding! Bravo!!

Response from developer
Thanks so much for the kind review!!
Poorly Designed App
So many strange quirks, weights reset whenever they please, excel sheet is more effective and efficient. Would be 5 stars if it worked with any consistency. Should not charge money for this.
Broken and no help with fixing it
Been using for years, but the newest update totally borked it.
Do not get this until
Fixed and certainly don’t pay for it.

The best!
Hands down the best workout app. I’ve tried many and haven’t even thought about another app since I got this one. Don’t cheat yourself get the lifetime membership. The owner of this app is the man! Super responsive, and really cares about his product.
Best App for Program Development / 531
If you are looking for an app to design a weight lifting program this is it. I’ve tried many different apps over the years: Strong, Strength Log, StrongLifts, 531 Strength, Boostcamp. This one works the best for me. Especially if you like to use a % based program. Many of the apps that I tried don’t have that feature. This app does plus a training max.
If you like 531 this is a no brainer.
Easy to make programs, easy to log in the gym, so many features that track your progress. Very polished and rich app.
I’d recommend anyone to try it for a week (free trial). Best part about it is it has a lifetime purchase option. After the week of using it I immediately bought the lifetime.

Best Strength Tracker hands down
I’ve been using this app for 3-4 years at this point. I’ve tried other apps but this one is always my benchmark. I’ve used it for stronglifts, 5/3/1 variants, made my own routines, etc.
It’s straightforward, easy to use, and it will auto calculate your next workouts weights based on your training maxes, which is something I have found other apps lack. It also has all the pretty graphs you could possibly want.
The pro version is worth every dollar. I really do love this app.

Great app, great developer
This app is amazing for tracking progress. My favorite feature is that you can set it to automatically adjust your max training weight after every workout, that way you’re always progressing without having to calculate your own weights. The app support is also phenomenal, the developer is very responsive and helpful in creating new features and fixing bugs as they pop up

Excellent App and support
I’ve been using KeyLifts for 3 years now. It was amazing 3 years ago and has only gotten better with each update. Zero issues with app performance and I love the ability to create my own templates. It’s fantastic for 5/3/1, ilbut not limited to that in anyway. Jimmy is also very responsive on support issues. If I could give 10 stars I would.

Best 5/3/1 App
Don’t be turned off by the overall rating of thsj app. I think it suffered from negative reviews in the early days. I gave all the top 5/3/1 apps a try and this one is the most polished and feature rich. It handles all the calculations, provides customizable plate math, has every template imaginable, great Apple Watch interface…everything I was looking for to let me focus on my workout instead of record keeping. Try the free workouts and then just pay for the app. The dev has done an incredible job.

Best Workout App
Automatically increases weights as you improve, shows you the weights to put on each side, and shows timers for each sets. You can also use an Apple Watch to check off each set. It’s such an amazing app that’s made by just one guy, I appreciate this app!
So Good That I’ll Write a Review
I never leave reviews on apps but this one truly deserves a 5-star.
This app has simplified (and gamified) my 5/3/1 workouts, and made it easy to track data about my strength over time. The app automatically calculates my 1-rep-maxes across all primary lifts, and displays them in graphs and charts in your ‘Profile’ tab. The graphs really motivate me since I can clearly see myself getting stronger over time.
Shoutout to the developer, too. I reported a bug within the app and they responded the next day saying they’ll fix the bug in the next release. Love that they’re constantly improving the app, instead of abandoning it.

Great lifting App
Lots of features with built in workouts and customization for any program. The developer actually responded to my email. He keeps adding features and it’s only gotten better over the years I have been using it. My wife uses it and doesn’t follow any 5/3/1 but is able to make her programs the way she wants. Keep up the good work.
