Incredible vs Athlytic: Training Context and Recovery Compared
Incredible combines sleep, overnight vitals, and recorded training as daily training context. Athlytic focuses on a recovery metric built from overnight signals.
Incredible is a free training and fitness app with integrated strength training. Athlytic is a popular recovery app focused on HRV and sleep metrics. Both run on Apple Watch and provide context for training. Here's how they differ.

The Core Difference
Athlytic calculates recovery from HRV, sleep, and resting heart rate — the standard recovery signals most apps use. It does this well and presents the data clearly.
Incredible takes a broader recorded-training approach. It provides daily training context from sleep, overnight vitals, recent training, and workouts recorded today. An optional check-in adds personal context. Logged strength workouts contribute through recorded workout load instead of being represented only by heart rate and duration.
Daily Training Context and Recovery
Both apps put overnight signals beside training data, but they present the result differently:
Athlytic derives recovery from overnight HRV, sleep duration, sleep quality, and resting heart rate. If your HRV is down and you slept poorly, you're told to rest. Simple and effective for general recovery.
Incredible includes sleep and overnight vitals, then accounts for recent training and workouts recorded today. A logged deadlift session therefore contributes through recorded strength workout load even when its average heart rate looks modest. The result is training context, not a prescription.
Strength Training
This is where the two apps diverge significantly.
Incredible includes a full strength training tracker — exercise library, set-by-set logging from your Apple Watch, and reusable templates. Logged lifts feed recorded workout load and Fitness while appearing in the app's daily training context.
Athlytic does not track strength training. If you log a lifting session, it captures the heart rate data but has no visibility into what exercises you did, how much weight you moved, or which muscles are fatigued.
Fitness Level Tracking
Incredible models recorded cardio and strength workout load at faster and slower rates. Fitness is training built over time from recorded workouts, not a complete measure of physiological fitness.
Athlytic focuses on recovery metrics rather than long-term fitness modeling. There is no equivalent fitness score tracking trends over time.
Vitals
Incredible tracks six vitals with trend charts: HRV, Sleep Score, Resting Heart Rate, Body Temperature, Blood Oxygen, and Respiratory Rate. Blood Oxygen is displayed separately from the daily training context.
Athlytic covers HRV, sleep, resting heart rate, and body temperature but does not surface SpO2 or respiratory rate data.
Pricing
Incredible is completely free. No subscription, no account, no ads. There is a voluntary tip jar if you want to support development, but nothing is locked behind it.
Athlytic offers a limited free tier and a premium subscription at approximately $5.99/month or $29.99/year for full access to recovery scores and detailed analytics.
Privacy
Both apps process Apple Health data on-device for insights. Incredible requires no account and does not sell health data or use it for advertising. Athlytic requires an account for premium features.
Who Should Choose What
Choose Incredible if you do strength training and want logged lifting work included in your daily training picture instead of represented only by workout heart rate. Also if you prefer a completely free, private experience.
Choose Athlytic if you are primarily a cardio athlete and want a focused recovery dashboard from an established app. Athlytic has a larger user base and longer track record.
Most recovery apps — Athlytic included — are blind to what happens in the weight room. They see heart rate and duration, but not the difference between a heavy deadlift day and a yoga session. If your training includes weights, that blind spot leaves a major input out of the recovery picture. Incredible closes that gap — and it's free.
