5/3/1 & nSuns Strength Tracker

Features & Capabilities

KeyLifts makes the 5/3/1 and nSuns programs effortless by removing the math from your workouts. It automatically calculates all sets based on your training max and shows exactly what to lift in the gym. With one button, you generate a complete cycle with weights calculated for you, start warm-ups, and stay on track for new PRs. Free features include PR alerts, rest timers, 150+ templates from the 5/3/1 books, custom templates, and the ability to track assistance and Joker sets.

Upgrade to Pro for automatic Training Max progressions, cloud backup and device sync, a Plate Calculator, and graphs of your one-rep maxes over time. Pro also adds Joker and assistance tracking, plus full Apple Health integration to sync weight and workout data.

User Reviews

KeyLifts is a feature-rich, highly customizable 5/3/1 tracking app with strong progress tracking, auto-calculation of weights, and robust templates. It shines in value, ongoing updates, and solid developer support, plus solid Apple Watch/iPhone integration. However, multiple reviews note stability issues after updates and occasional quirks in behavior, which can affect reliability. For serious lifters who want deep customization and strong support, it remains a top choice, provided they’re comfortable with the potential for bugs between releases.

Pros

Powerful tracking with endless customization and templates, letting you design and log a wide range of programs (including 5/3/1) with detailed progress tracking.
Automatic progression and weight calculations (auto-adjusting training maxes and PR tracking) that keep you progressing without manual math.
Great value and active development (lifetime subscription available, frequent updates, and responsive support).
Excellent developer support and reliability in addressing bugs; fast responses and patches.
Excellent Apple Watch and iOS integration for logging, timers, and on-the-go use.

Cons

Bugs and stability issues after updates: weights can reset and features may break, impacting reliability.
Occasional quirks and inconsistent behavior: non-critical but reported as annoying or unpredictable.

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!!!

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.

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.
