Alta pods + app

Every rep, measured.

Two small pods stick to the bar and show how fast every rep moved, live on your iPhone and Apple Watch.

The pod

Two pods. Any bar.

They stick to steel. One goes on each end of the bar, or one on each dumbbell.

  • GripA finger dimple on every side, so it's easy to grab and pull off.
  • UndersideTwo contacts, held to its case by magnets. A bigger magnet holds it on the bar.

How it works

Clip. Lift. Know.

  1. 1

    Clip

    Press a pod onto each end of the bar. The magnet does the rest.

  2. 2

    Lift

    Start your set. Alta finds the reps on its own.

  3. 3

    Know

    Each rep's speed is on your phone before you rack the bar.

Live set

The bar doesn't round up.

Reps are counted from the bar's motion as they happen. Every rep gets its own speed, in metres per second.

App screens on this page are illustrations with example numbers.

Speed drop

Stop when the bar says so.

Pick a goal. As reps slow down, Alta tracks the drop from your fastest rep and tells you when to rack it, before grinding reps eat into the next set.

Between sets

Rest timed. Plates counted.

The rest clock starts when the set ends. The plates for the next set are already worked out.

Progress

Your best, on record.

Every set lands in your history. Alta works out your max from how fast the bar moved, charts it lift by lift and marks each new best.

Why bar speed

Speed is how hard it was.

Heavier weight, slower bar. Same weight but a slower bar, and you're tiring. That's velocity-based training: the bar tells you what effort feels like, as a number.

  • Speed drop says when a set has done its job.
  • Your max comes from your own load and speed, not a chart.
  • Next load is suggested from how the last set moved.

FAQ

Questions, answered.

What does Alta measure?

Each rep's speed as the bar goes up, the number of reps, and how much slower your reps get across a set (the speed drop). From your sets it also works out your max for each lift.

Why two pods?

One goes on each end of a barbell, or one on each dumbbell.

Will it stay on my bar?

The pod holds on with a magnet in its base, so it needs steel: barbell sleeves, dumbbell handles, machine weight stacks.

Do I need an Apple Watch?

No. Everything works on iPhone. The watch app is there if you'd rather keep the phone in your bag.

How accurate is it?

We won't put a number on it until we've tested pods against a reference device and can publish how we did it next to the result.

How long does the battery last?

We'll publish battery life once it's measured on the pods we ship.

How much, and when?

Price and ship date aren't set yet. Join the waitlist and you'll get one email when they are.

Android?

Not for now. Alta is built for iPhone and Apple Watch.
