Question 1

What is Incredible?

Accepted Answer

Incredible is a health and fitness app for iPhone and Apple Watch. It turns Apple Health, Apple Watch, workout, sleep, recovery, and training data into personal fitness and wellness insights. It is for general fitness, wellness, and personal reflection, not medical advice.

Question 2

How does the readiness score work?

Accepted Answer

Your readiness score (0-100) is calculated from the health and training data you allow, including sleep, HRV, resting heart rate, vitals, recent workout load, and strength training context. Health and device data can be incomplete or inaccurate, so use it as wellness guidance, not for medical decisions.

Question 3

Do I need an Apple Watch?

Accepted Answer

An Apple Watch is recommended for the best experience - it provides HRV, heart rate, and workout tracking data automatically. The strength training logger also works from your wrist. Without a Watch, Incredible can still use health data from other HealthKit sources.

Question 4

What health data does it use?

Accepted Answer

Incredible uses Apple Health data you allow, such as workouts, activity, heart rate, HRV, resting heart rate, sleep, respiratory rate, blood oxygen, temperature, body measurements, mobility, daylight, and related fitness metrics. It may also use age and biological sex from Apple Health for heart-rate zones, app data you create, Apple Watch workout/dashboard data, and location only for sunrise and sunset times.

Question 5

Which languages are supported?

Accepted Answer

Incredible launches in 21 languages.

Question 6

How does strength training work?

Accepted Answer

Start strength workouts from iPhone or Apple Watch, use routines, and track completed sets. Strength sessions become part of your workout history and training load alongside the rest of your training.

Question 7

What is the fitness score?

Accepted Answer

The fitness score uses CTL/ATL modeling (chronic and acute training load) - the same formulas used by TrainingPeaks. It tracks your fitness level over time based on both cardio and strength training data. Most fitness apps only track cardio load.

Question 8

How is Incredible different from Athlytic, Whoop, or other recovery apps?

Accepted Answer

Incredible brings readiness, training load, strength workouts, vitals, and long-term fitness trends into one free, private app. No account, no ads, no subscription, and no selling health data.

Question 9

Is my health data private?

Accepted Answer

Yes. Incredible reads Apple Health data through HealthKit and processes it on your devices for readiness, recovery, fitness, sleep, vitals, and workout insights. We do not send Apple Health data to our servers or analytics providers, sell personal data, use health data for ads, or track you across other companies' apps or websites.

Question 10

Do you collect any personal data?

Accepted Answer

There is no Incredible account. Supported app data may stay on your device or sync through Apple's private iCloud and CloudKit for your Apple ID. The app may send limited product analytics, such as launches, onboarding, Health access requested or skipped, selected tabs, and general interaction events, but not Apple Health values, workouts, readiness scores, screenshots, names, email addresses, or account IDs.

Question 11

How do I report a security issue?

Accepted Answer

Email hello@incredible-app.com. We acknowledge reports promptly.

Question 12

Is Incredible really free?

Accepted Answer

Yes. No subscription, no account, no ads. Incredible is free. Optional tips are processed by Apple and do not unlock features, content, or services.

Question 13

Why is it free?

Accepted Answer

We believe health data insights shouldn't require a monthly subscription. Your Apple Watch already collects the data - you shouldn't have to pay again to understand it.

Question 14

How do I submit a bug report or feature request?

Accepted Answer

Use /feedback for product requests. Do not include health data, payment details, credentials, or confidential information in public request fields; use /contact for private support.

Question 15

How do I get in touch?

Accepted Answer

Email hello@incredible-app.com or use the contact page at /contact.
