AetherStrengthTraining that explains itself

Training and nutrition

It tells you what weight to lift. And why.

Most apps just log your sets. This one decides your progression with your own numbers in front of it, explains why, and lets you overrule it.

Prop up your phone, train, and forget about logging

You set your phone two or three metres away, side-on, and train without touching it. The app counts your reps, measures how many you had left from how the set slows down, logs it, starts your rest and adjusts the weight for the next set.

Counts

Your reps, with the phone’s camera. No wristband, no sensors, and no video uploaded anywhere to count them.

Measures

How many you had left, from how the set slows down: if the last rep comes up 18% slower than the fastest one, you had about three left. It measures it instead of asking you.

Decides

It logs the set, starts your rest and, if it was too easy or too hard, adjusts the weight for the next one. It tells you why.

And you talk to it, without letting go of the bar

  • “It was seven”fixes the rep count
  • “Make it 100 kilos”changes the weight
  • “More rest”lengthens the break

And it comes with more

  • Train together, liveTwo people, each on their own phone, see each other’s sets as they train and cheer each other on.
  • Gym leagueYour gym against the others in your city, by weeks completed: everyone against their own goal, and the average counts, not the size. See the league (in Spanish)
  • Creator programsA coach or a creator shares their program with a link: you see the first week and, with the Club, load it into your app.
  • Consistency milestones4, 12, 26 and 52 weeks in a row hitting your goal are celebrated once, with their badge and a card to share.

What’s inside

How it decides

Three things go in. One comes out.

Without a watch it still works: on sleep and load.

Inside the app

It doesn’t log what you did. It decides with you.

Training

Your program, built for you

You start with a ready-made program for your sport, free. Generating one with AI or turning your coach's PDF into a routine are part of the Club: €9.99 a month or €79.99 a year, with 14 days free. Your records and weekly volume, always in view.

  • Every weight increase comes with its reason
  • The plates for each side of the bar, worked out
  • A button to overrule it
Nutrition

Your calories adjust themselves

To your real weight, not to a chart. If your weight stalls, the target is recalculated and it tells you. AI scanner (two analyses a day on the free plan), barcodes, and recipes that fit what’s left of your day.

  • “950 kcal and 28 g of protein left” — with ideas that fit
  • Your whole week at a glance
Aether Coach

A coach that already knows your history

Ask it anything: it answers with your data in front of it — your streak, your kcal, your records. “What do I cook with what’s in the fridge?” and “Do I add weight this week?” are the same conversation.

Community

Training sticks when you level up

Ranks, achievements and a weekly league with your friends. Your volume and sessions earn XP: consistency you can watch climb.

Side by side

Seven differences. And one thing both do.

And also

What a screenshot doesn’t show

Bring your history

Coming from Strong or Hevy? Your sessions and records come with you. It tells you how many made it in and what was left out — never an “imported ✓” over a half-read file.

See it now with your CSV: read in your browser, never uploaded (page in Spanish)

It knows how to come back

After weeks off it won’t suggest the weight you left at. It drops the loads for the first sessions and explains why. You decide.

On your lock screen

Your streak and remaining calories in a widget. And you can ask Siri how many you’ve had today without opening anything.

Your progress is yours

A backup so changing phones doesn’t cost you years of training, and a public page only if you switch it on.

Blocks with an end date

Six weeks with a closing date from day one. When they end it sums up what actually changed, measured on your best sets.

It doesn’t scold you

Sunday’s summary arrives even after a bad week. It tells you how it went without grading you, and ends with one concrete thing to do.

It knows how you arrived today

It reads last night’s sleep from Health and, if you wear a watch, your HRV and resting heart rate. With that and the last few weeks’ load it decides what to propose: the day after five hours of sleep is not the day after eight. Without a watch it still works, on sleep and load.

Your allergies, in your own words

You write “allergic to nuts and shellfish” the way you’d say it, and it applies to all thousand recipes and to your week’s plan. Dish by dish, from the ingredients — not from a hand-typed tag someone got wrong. Traces still depend on the manufacturer: that label you still have to read.

Before you install it

What everyone asks

What does it cost?

Training, eating, your history and your records are free. The Club costs €9.99 a month or €79.99 a year, both with 14 days free, and adds your 12-week program built by the AI, technique checked on video, your coach’s PDF turned into your routine, your full meal plan (carbs and fat balanced, your budget, your time to cook and the shopping list with its cost), and more AI: up to 20 Coach messages and 10 food photos a day (5 and 2 on the free plan), within 400 credits a month. Apple bills it and you cancel from your account. Prices in Spain, VAT included.

Do I need a coach to use it?

No. The app decides your progression on its own and explains every call. If you also want a person behind it, you find one in the directory and connect — but that’s an option, not a requirement.

I’m coming from another app. Do I lose my years of training?

No. Export the CSV from Strong or Hevy and it all comes with you: sessions, records and charts. Before saving anything it tells you how many it read and what was left out, so you don’t have to trust it blindly.

What happens to my data?

Your progress lives on your phone, with a backup in your account so changing phones costs you nothing. Your public page only exists if you switch it on, and switching it off deletes it.

How accurate are the food photo and the weight adjustment?

The photo is an estimate, and the app says so: it suggests foods and grams, and before logging you fix them, remove what isn’t yours and add the oil. The weight adjustment doesn’t guess: it comes from what you log (reps and RIR), shows its reason, and you can keep the old weight.

What does the AI know about me?

Only what it needs to answer you, and only if you say yes the first time you use an AI feature. It never gets anything from Apple Health, your allergies and intolerances, or your name. In the app, «Coach Memory › See what the Coach reads» shows exactly what is sent. The Coach is an AI: it guides you, can get things wrong and doesn’t touch what your professional sets.

iPhone only?

For now, yes. Android will come, but we’d rather do one thing properly than two halfway.
