If you're looking at Athlytic, you probably want your Apple Watch to tell you each morning whether to train hard or back off. FITIV and Athlytic both do that, from the same overnight HRV and resting heart rate data. Where they part ways is your workouts. Athlytic is a focused recovery app that sits alongside whatever you use to log training. FITIV is also where you log it, including strength sessions set by set, and its readiness score takes your recent training into account.
Where FITIV and Athlytic Differ
Both apps cover the basics: an HRV-based Recovery score, a sleep score, training load, live Apple Watch workouts with heart rate zones and GPS, and a structured workout builder. They differ in a few areas that matter if you train regularly.
| FITIV | Athlytic | |
|---|---|---|
| Strength training | Logs exercises, sets, reps, weight, and rest | Counts the session's heart rate toward Exertion and your weekly strength days; no exercise or set log |
| Daily readiness | Training Readiness combines Recovery with your recent strain and training load | Recovery from HRV and resting heart rate, plus a Target Exertion range for the day |
| Workouts without an Apple Watch | iPhone with a Bluetooth chest strap, AirPods Pro 3, or a Garmin watch broadcasting heart rate | Apple Watch needed for most features |
| Garmin and Fitbit | Direct Garmin Connect and Google Health connections | Through Apple Health only; Garmin HRV needs a separate sync app or manual entry |
| Sleep | Sleep score with efficiency, REM, deep sleep, and heart rate dip | Sleep score with stages, efficiency, and heart rate dip, plus sleep debt, consistency, and latency |
| Challenges and leaderboards | Yes, with friends or groups | No (you can share your scores and workouts) |
What Athlytic Does Well
Athlytic is built around one question: are you ready to train hard today? It answers it with scores you can read in a few seconds, and gives you a Target Exertion range so you know how much to do. You don't have to change how you log workouts to use it, so it's an easy addition if you already have a training app you like.
Its sleep section also goes into more detail than FITIV's, adding sleep debt, consistency, and latency to the stages, efficiency, and heart rate dip both apps show. It focuses on one job, so it's quick to learn: open it, read your score, and get on with your day.
What FITIV Does Differently
Your Workouts Count Toward Readiness
FITIV's Training Readiness card on the Today tab starts from your Recovery score (overnight HRV, resting heart rate, and sleep), then factors in the strain and training load from your recent workouts. A hard week of training shows up in the score even after a good night's sleep. Each day is rated Poor, Low, Moderate, High, or Prime.
Athlytic tracks training load too, in its Trends, and keeps it separate from your daily Recovery score.
Strength Sessions Logged Set by Set
FITIV's strength tracking logs each exercise with sets, reps, weight, and a rest timer, and charts your estimated one-rep max and personal records over time. You can save sessions as templates and apply progressive overload recommendations to an exercise when you're ready to add weight. Athlytic tracks a lifting session through its heart rate and counts it toward your weekly strength days, but it doesn't log the exercises, sets, or weights.
In both apps, a lifting session's training load is based on effort, not on the weight you moved. FITIV uses your heart rate by default, or you can rate how hard each session felt with Perceived Effort.
More Ways to Get Heart Rate
You don't need your watch for every workout. Record a FITIV workout on your iPhone with a Bluetooth chest strap and you still get heart rate zones and training load, or use AirPods Pro 3 for heart rate. If you also own a Garmin or a Fitbit, FITIV connects directly to Garmin Connect and to Google Health for Fitbit, and both bring overnight HRV into your Recovery score.
Challenges With Friends
FITIV has challenges and leaderboards you can join with friends or a group, with goals like workouts, distance, or FITIV Points, and see where everyone stands as the challenge goes on.
Who Should Choose FITIV
- You want your readiness score and your workout log in one app
- You lift and want sets, reps, and weight tracked next to your heart rate data
- You train with a Garmin watch, a Fitbit, or a chest strap as well as (or instead of) an Apple Watch
- You like doing challenges with friends
Who Should Choose Athlytic
- You already log workouts in an app you like and only want a recovery score on top
- You want more detail on your sleep
- You want a dedicated recovery app rather than an all-in-one training app

Frequently Asked Questions
Does FITIV have HRV tracking like Athlytic?
Yes. FITIV reads your overnight HRV from Apple Watch, Garmin Connect, or Google Health and uses it, with resting heart rate and sleep, in a daily Recovery score. That feeds Training Readiness, which also accounts for your recent strain and training load.
Can Athlytic track strength training?
Not set by set. Athlytic records live workouts on Apple Watch and counts a lifting session's heart rate toward Exertion, but it doesn't log exercises, sets, reps, or weight. FITIV logs each exercise with sets, reps, and weight.
Does FITIV work with Garmin watches?
Yes, in two ways. FITIV connects directly to Garmin Connect for your Garmin workouts, sleep, HRV, and daily metrics, and many Garmin watches can broadcast heart rate to FITIV as a live sensor during a FITIV workout. Athlytic reads other wearables only through Apple Health.
Can I use both FITIV and Athlytic?
Yes. Both read your Apple Watch data from Apple Health, so they can run side by side. You could use Athlytic for its morning check-in and FITIV to log your training, though FITIV's Training Readiness gives you a morning check-in too.
