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. simple and works exactly as it should one time payment vs subscription based is a plus. only wish is that it had a plate calculator for both kg and lb (and easily switchable from workout screen). i paid for the plate set addon but it doesn't account for this. my gym has both at different stations so the math gets a bit annoying. switching between kg/lbs also doesn't convert the amounts, it just changes the unit (e.g. 225lb bench becomes 225kg bench lol)

Not bad but with little hickup . The plate weight picture ( the one which show plates for loading the bar ) is not quite visible . It's right on edge of the oval . It would be nice also to have possibility to adjust weights on sets and assistance workout . How do you record if set cannot be completed because the weight is just to heavy and need to be reduced to winish set ?

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.
