## What is KeyLifts?

KeyLifts takes the math out of the 5/3/1 program so you can focus on getting stronger. Everything is planned out for you. Know exactly what you need to do as soon as you step into the gym. KeyLifts automatically calculates all your sets so you can focus on hitting new Personal Records.

Planning and tracking a 5/3/1 program is time-consuming and hard. You have to calculate your training max and then calculate every single set based on your training max. It doesn't have to be like that. You could just walk into the gym every day knowing exactly what you need to lift. KeyLifts takes the math out of the 5/3/1 program so you can focus on getting stronger and hitting new PRs.

Every cycle you have to redo the entire planning process, but not anymore! With one button press, you can create a new cycle with all the weights automatically calculated for you. 

If you haven't hit your ultimate strength goals yet then maybe it's because you have to spend so much time at the gym calculating weights for each set. Stop wasting your precious energy. Just plug in your numbers to KeyLifts and go.

The 5/3/1 program is amazing for strength gains but your energy and time are wasted trying to figure out what plates you need for each set. In the upgraded Pro version you get a Plate Calculator so you focus on the things that matter.

Getting stronger is about putting in the work every week but it's hard to see the progress you are making. The Pro version includes graphs of your one-rep maxes over time. Feel confident knowing you are doing the right things and making progress.

If you are the type of person that likes to track everything the Pro version also includes the ability to add and track Joker sets and assistance exercises.

Free Features:
- Plan an entire 5/3/1 cycle with one button press
- Alerts when you hit a new Personal Record (PR)
- Warm-up sets
- Rest Timer
- 150+ templates from the 5/3/1 Books
- Build your own custom templates
- Track assistance exercises
- Track Joker sets
- Delete or swap exercises during a workout

### 5/5 — This app is probably the best lifting log out there

*2026-07-05*

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!

### 5/5 — Great App for 531 and more

*2026-03-04*

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!!!

### 5/5 — Essential of 5/3/1

*2025-11-21, version 5.17.0*

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.

### 5/5 — Great

*2025-07-29, version 5.16.4*

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

### 5/5 — Such a great app

*2025-07-03, version 5.16.1*

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!

### 5/5 — Best Lifting App Period

*2025-05-20, version 5.14.9*

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.

### 5/5 — Incredible App for tracking numbers

*2025-04-11, version 5.14.4*

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.

### 5/5 — 2025 FERRARI OF 5/3/1!

*2025-02-14*

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!!

**Developer response:** Thanks so much for the kind review!!

### 1/5 — Poorly Designed App

*2025-01-07, version 5.12.3*

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.

### 1/5 — Broken and no help with fixing it

*2024-11-29, version 5.11.11*

Been using for years, but the newest update totally borked it. 
Do not get this until
Fixed and certainly don’t pay for it.
