About this app

The latest app for weightlifters doing Jim Wendler's 5/3/1 program! Five/Three/One is a focused and intuitive app helping you achieve what really matters: Getting Stronger.

No more bringing a crumbled workout sheet to the gym, no more messing around spreadsheets to update your weights. From calculating your cycles, to telling you what plates to put on the bar, Five/Three/One does it all.

Features include:
- Planning and scheduling your whole 5/3/1 cycle
- Charting your progress
- Rest timer with notifications
- Automatic plating calculation
- Calculating your next cycle based on your performance
- Notes associated with each sets
- Home screen widget showing your your current and upcoming workouts
- Lbs/kg support

Optional paid features:
- Customize which plates you're using and change your barbell's weight
- Customize templates assistance work and define your own exercises
- Beyond 5/3/1 templates and options, from Joker Sets to FSL, Pyramid and much more!

As weightlifters doing 5/3/1 ourselves, we made the app we wanted after being dissatisfied with what was out there. More than just a glorified spreadsheet, we designed it to be focused on each task at hand. With even more great features in the pipeline, we're stoked to release the app for others to use and can't wait to hear your feedback!

We use it, we love it, and we're sure you will too.

Great app when it's working, exactly what you need for progressive overload. However, the app keeps deleting my weights on my accessorys. I've saved them 4 times now, then they'll just randomly disappear after a week or so which is extremely frustrating as it's stopping me progressing. Please fix this issue

So far this app is exactly what I needed to start doing 531 from 5x5. I love that it's subscription free as I would always rather pay for something up front as opposed to be kept on the hook forever. One feature that I would like to see is the ability to swap out assistance work mid routine if, for example, a machine or equipment was unavailable.

Solid app for tracking 5/3/1. Free has options for BBB and I've paid for the pack that includes FSL. The timer and associated notification doesn't work if the app isn't open or the screen is unlocked which can be annoying and lead to taking long rests. There is a timer for BBB sets but not any other template which is again annoying as I don't need to rest for 3 minutes for FSL. It's a clean looking app and with a bit of polish it would be 5 stars
