Whatever you train, it lands in the same place — the same stats, the same plan, the same feed. No more stitching five apps together.

Strength

Log every set. Fast.

Weight, reps and reps in reserve, with your last session and a rest timer on the same screen. Drop sets, partials and supersets are first-class, not a note in a comment field.

BuildX AI · Included with Edge

Say what you want.
Get the plan.

Describe a goal or a session in your own words. BuildX AI builds it with the same engine and exercise library as the rest of the app — so what you get is something you can actually train.

It’s off-season for three months. Improve my strength, speed and endurance — I want to run twice a week and lift three times.

BuildX AI replying with a 14-week plan: runs and lifting sessions placed through each week

Honest about your goal

Plans come from BuildX’s training engine. If a race goal can’t be reached safely by the date, it says so — and offers a later date or a shorter goal instead.

Built from your training

It reads your recent training and experience, and steers lifting around the injuries you’ve logged.

Change it by asking

“Swap the bench for dumbbells.” “Move the race.” “Four runs a week.” The card updates in place.

You stay in charge

Nothing is created until you say so. Review it, edit it in the builder, then make it yours.

Prefer tapping?

Pick the muscles and the time you have, and the workout generator builds the session.

Progressive overload

Getting stronger
shouldn’t be guesswork.

Pick how you want an exercise to progress and BuildX Performance carries it forward for you — reading what you actually completed last time, then setting the next target. Turn it on per plan, and switch method whenever the goal changes.

WeightIncreases the load by about 10% once you complete every set, rounding up to the next weight you actually have.

RepsAdds two repetitions to each set once you hit the current rep target consistently.

Extra setAdds another set to the exercise when all of the current sets come back completed.

Reduced restShortens the rest between sets a little at a time, when conditioning is the goal.

The BuildX Performance progressive overload settings: weight, reps, extra set and reduced rest, with weight selected

And when a straight set isn’t the point.

Drop sets, partial reps and supersets are first-class in the logger — not a note you leave yourself in a comment field.

Drop setsTake the set to failure, strip the weight and keep going. Each drop is logged with its own load and reps, so the volume counts and the next session knows where you finished.

Partial repsReduced range-of-motion reps at the end of a set, recorded separately from the full ones — the extra work shows up in your volume without inflating your rep target.

SupersetsPair exercises together and the app moves you between them, keeping one rest timer across the pair instead of two.

Partial reps logged in BuildX Performance: two partials recorded after a set of lying leg curls

A drop set logged in BuildX Performance: 10 reps at 125 kg, then 4 reps at 120 kg and 3 reps at 110 kg

ONE SET. THREE LOADS. ALL OF IT COUNTED.

Let’s talk

What is BuildX Performance?

One app for everything you train: lifting, running, cycling, swimming and triathlon. Plan it, log it on your iPhone or Apple Watch, and see what it added up to. BuildX AI builds plans and workouts from what you tell it, and BuildX Performance Coach connects you with a coach if you work with one.

What can BuildX AI do?

Describe a goal or a session in your own words and it builds a training plan or a workout with BuildX’s own engine and exercise library. It uses your recent training, steers around injuries you have logged, tells you honestly when a race goal is not reachable safely, and changes the plan or workout when you ask. Nothing is created until you review it and say so. BuildX AI is part of Edge.

Which sports does it support?

Strength training, running, cycling and swimming, together with triathlon plans and stats. Record on iPhone or Apple Watch, or import activities from other apps and watches through Apple Health or Health Connect.

Is it free?

Yes, Core is free: logging, recording, importing, the feed and your records. Pulse adds the lifting toolkit, such as progressive overload, plan analysis and recovery. Edge adds BuildX AI, multi-sport and race plans, workout generation and advanced stats. Prices are shown in the app in your currency.

Can I download the app now?

Public store links are not on this page yet. Use “Request app access” to email us about availability for your device, and we’ll help you with the next step.

Do I need a coach to use it?

No. You can build and follow your own workouts and plans, or let BuildX AI build them. If you work with a BuildX Performance coach, your assigned programming and the data you choose to share keep you connected.
