EVERY MORNING, BEFORE YOU ASK

Three numbers, and you know what today allows

Everything is measured against your own 30-day norm, not other people's averages. Plus a morning journal that shows what actually correlates for you – alcohol, stress, caffeine, sauna – always with an effect size, never sold as a cause.

91
SLEEP

How much of your personal need you actually covered.

72
RECOVERY

From HRV, resting heart rate and sleep – against your own 30-day norm.

65
LOAD

What the day has cost you, plus a target range for today.

Guidance for your training, not a medical diagnosis. Works with data from Apple Health, regardless of which compatible wearable provides it. No extra hardware and no second subscription for it.

01 · GETTING STARTED

From nothing to your first score: one night

No account, no registration, no order to place. What you need is already on your wrist.

STEP 1

Grant Apple Health access

One dialog, one tap. LeibFit reads sleep, HRV and resting heart rate from the watch you already own – Apple Watch or any wearable that writes to Apple Health.

about 1 minute
STEP 2

Say once what you have

Dumbbells, barbell, machines, bands or bodyweight only – per training location. After that LeibFit never plans an exercise you cannot do.

about 2 minutes
STEP 3

Sleep on it once

Next morning your three numbers and today's workout are on the first screen. Without you having to open the app beforehand.

next morning
02 · THE NUMBERS

Knows when you can push – and when to recharge instead

Three scores, every morning: recovery 0–100 from HRV, resting heart rate, and sleep – measured against your own 30-day norm, not other people's averages. Sleep with a need model and bedtime recommendation. A load score of 0–100 with a daily target that adjusts to your recovery. Strength training counts too – not just what your pulse gives away: heavy sets barely move your heart rate but still cost you. Plus a morning journal that shows what actually correlates for you – alcohol, stress, caffeine, sauna – always with an effect size, never sold as a cause.

Guidance, not diagnosis. Works with any wearable that writes to Apple Health – no extra hardware and no second subscription needed for it.

Health tab in LeibFit with the drivers of recovery: HRV 51 ms against a 49 ms average, resting heart rate 59 bpm against 61 bpm, and 7 hours of sleep – each compared against your own 30-day norm, with vitals and the 30-day trend below
ON YOUR WRIST

Even when the iPhone stays in your pocket

On Apple Watch you get your three numbers and today's workout: tick off sets without picking up your phone. The rest timer runs on your wrist, and heart rate and elapsed time are right there during the session. The watch records the workout and writes it to Apple Health.

Tick off sets Rest timer Heart rate & time Complication

If your iPhone is somewhere else, ticked-off sets aren't lost – they travel over as soon as it is back in range. watchOS 10 or newer, included in the price: no second subscription for the watch.

03 · THE TRAINING

AI coach or build it yourself

Let your weekly plan be generated for you – or build it day by day yourself. Exercises, sets, reps, weight, rest: full control, whenever you want it.

The AI coach plans for you

A few questions in chat, then your weekly plan is ready. The coach runs on Apple Intelligence directly on the device – your answers never leave your iPhone.

Or build it yourself

For anyone who wants control instead of prescriptions. Every exercise, every set, every weight, every rest period – you decide. Like your old spreadsheet, just faster.

PLANS WITH WHAT YOU HAVE

Knows your equipment

Tell it once what you have: dumbbells, barbell, machines, bands, or just bodyweight. LeibFit only plans with what's actually available to you – at home, at the gym, or a mix of both.

IN THE SESSION

Train without keeping count

And you always see what you managed last time.

EXECUTION

Everything at a glance

The whole session at a glance, every set checked off directly. The exact reason many people stick with their spreadsheet – just better.

Training view in LeibFit: 4 of 23 sets checked off, back squat at 165 lb, plus the rest timer running at 2:24
PROGRESSION

Suggestions that think ahead

Hit all your reps, and the weight goes up a notch next time. If your recovery is in the tank, the increase waits. Always explained, never silent – and capped by your real equipment.

Weekly plan workout in LeibFit: upper body and back with seven exercises, each with sets, rep range, RIR, and rest time – planned for home, using only equipment you actually own
A timer that actually runs

Starts by itself after every set and keeps running reliably in the background – the alert comes through even if the app was closed long ago. Even big apps fail at this.

05 · FREQUENTLY ASKED QUESTIONS

Questions & answers

Do I need any extra hardware for LeibFit?

No. LeibFit calculates recovery, sleep, and load from the data your smartwatch already measures. It works with the Apple Watch and any wearable that writes its data to Apple Health – no extra wristband and no second subscription for the analysis.

What does LeibFit cost?

The first 7 days are free – no payment details and no automatic renewal. After that LeibFit Premium is €6.99 per month or €44.99 per year – cancel any time, directly via the App Store.

Do I need a subscription for the free trial?

No. You download the app and can use all of it for seven days – no payment details and no automatic renewal. After the seven days you decide whether to take LeibFit Premium. If you do not, nothing happens: nothing is charged, and your data stays on the device.

Does LeibFit work without an account and without the cloud?

Yes. LeibFit needs no account and no registration. Your training, your equipment, and your health data stay entirely on your iPhone – there is no server anything gets uploaded to, and no analytics SDK inside the app.

How does LeibFit calculate my recovery?

Every morning, a recovery score from 0 to 100 is calculated from your heart rate variability (HRV), your resting heart rate, and your sleep. It is always compared against your own 30-day norm rather than other people's averages. The score is guidance for your training, not a medical diagnosis.

Can I build my own training plan, or does the AI create it?

Both. The AI coach creates a weekly plan after a few questions, containing only exercises that match your actual equipment – whether home gym, studio, or bodyweight only. Or you build every training day yourself: you decide the exercises, sets, reps, weight, and rest.

Can LeibFit read the data from my Amazfit band?

Today via Apple Health: if the Zepp app writes your Amazfit band's night data to Apple Health, LeibFit works with it. But that chain has one link that waits for you – Zepp only transfers reliably once you open the app. That is why the direct connection is being built: LeibFit reads the band itself, at night, over Bluetooth, with no detour through Zepp. It is not in the App Store yet; on the Helio Strap guide page you can sign up for exactly one notification.

What devices does LeibFit run on?

LeibFit runs on iPhone from iOS 17.6 and on Apple Watch from watchOS 10. The AI features (coach chat and plan generation) require an iPhone with Apple Intelligence and iOS 26 – planning, logging, history, recovery, sleep, and load all work without AI too.

Is there a LeibFit app for Apple Watch?

Yes. On the watch you get your three numbers for the day and today's workout: tick off sets without picking up your phone, the rest timer runs on your wrist, and you see heart rate and elapsed time during the session. The watch records the workout and writes it to Apple Health. If your iPhone is somewhere else, ticked-off sets aren't lost – they travel over as soon as it is back in range. Plus a complication for your watch face. The watch app is included in the price; there is no second subscription.
