The simplest comparison on this site
Athlytic was one of the first apps to notice that an Apple Watch records everything a WHOOP does and to build a clean recovery score on top of it. That is still what it is. It has a clear score, good trends, excellent watch integration, and a price that is difficult to argue with. It has stayed narrow on purpose, and narrow is a legitimate product strategy.
Helix is the opposite bet: the daily score is table stakes and should be free, and the value is in what you can build on top of it once you know how recovered someone is.
Neither of those is wrong. They just suit different people, and the honest way to choose is to ask how many questions you want your app to answer.

| Hardware | None, uses your Apple Watch | None, uses your Apple Watch |
| Subscription | $24.99/year | $59.99/year |
| Free tier | Basic recovery scoring, with trends and deeper analytics behind Pro | Recovery score, strain, sleep and stress, free forever, with no account and no trial clock |
| Runs on | iPhone and Apple Watch | iPhone and Apple Watch |
| 3-year cost | $74.97 | $179.97 |

List prices in USD, cheapest tier that unlocks the full product, hardware counted once. The app-only products assume you already own an Apple Watch. If you do not, add roughly $249 for an Apple Watch SE, once, and note that it is a watch as well as a sensor.

Note what the chart is not saying. Athlytic Pro at roughly $75 over three years is cheap, and if it gives you everything you need then Helix Pro is $105 of features you were not going to open. Price only matters against what you use.
What Athlytic does well
Focus. One score, presented clearly, with trends that are easy to read. There is no menu to get lost in, and for a lot of people that is the entire point.
Watch-first design. The complications and watch app are mature and reliable, which is not universal in this category.
Price. Around $24.99 a year is the lowest ask from any credible product here, and the free tier is usable rather than a demo.
Athlytic does well
- Clean single recovery score with no learning curve
- Around $24.99 a year, the cheapest paid tier in the category
- Mature Apple Watch app and complications
- Long track record, and it does what it says on the tin
Where it falls short
- Deeper HRV analytics and trends sit behind Pro
- No per-muscle recovery model
- No structured VO₂max test protocol or race predictions
- No bloodwork, no experiments, no circadian energy planning
What Helix adds, and whether you need it
Take these one at a time and be honest with yourself about which ones you would actually open.
Per-muscle recovery. A single recovery number treats your body as one system, which is fine for cardiovascular readiness and useless for planning a lifting week. Helix deposits fatigue from every logged set onto the muscles that exercise targets, using a 173-exercise catalog with involvement weights, then decays it over muscle-specific windows of roughly 40 to 72 hours. Worth it if you follow a split. Irrelevant if you only run.
VO₂max Lab. A GPS-measured Cooper test, guided 4x4 intervals, lactate threshold detection, a forecast cone with a goal ETA, and VDOT race predictions. Worth it if you race or care about your engine improving on a schedule. Irrelevant if VO₂max is just a number you glance at.
Bloodwork and experiments. Panel upload with every marker scored against age and sex specific ranges, plus protocols targeted at a specific marker with a predicted response curve. Worth it if you get blood drawn more than once a year.
Energy Schedule. A circadian energy curve anchored to today’s actual wake time, adjusted for recovery, sleep debt, workouts and naps. Small feature, changes how people schedule hard sessions.
Strain that refuses to lie. Helix computes whole-day load from real heart-rate presence using per-workout Banister TRIMP plus background load and active energy, against a ceiling that moves with this morning’s recovery. On a day with no heart-rate data it shows a dash rather than a confident zero.
| Feature | Athlytic | Helix |
|---|---|---|
| Morning recovery score | Yes | Yes |
| Free daily recovery | Basic | Full |
| Free strain and stress | Partly | Yes |
| Sleep stages and debt | Yes | Yes |
| Apple Watch app and complications | Yes | Yes |
| Per-muscle recovery | No | Yes |
| Strength logging with templates | No | Yes |
| Cooper test and guided intervals | No | Yes |
| Race time prediction | No | Yes |
| Bloodwork analysis | No | Yes |
| Circadian energy schedule | No | Yes |
| AI coach on your numbers | No | Yes |
| Annual price of the paid tier | about $24.99 | $59.99 |
The verdict
Choose Athlytic
You want one number, cheaply, and nothing else
Athlytic is a good app at a fair price that has never pretended to be a platform. If your morning routine is a single glance at a recovery score and your training is mostly cardio you already know how to plan, there is no argument for switching and we are not going to invent one.
Choose Helix
You want the layers under the score, and you would rather not pay for the score itself
The daily loop is free, which already undercuts a $24.99 subscription, and $59.99 a year buys per-muscle recovery, a real VO₂max testing protocol, bloodwork scoring and self-experiments. The right choice if you lift on a split, race, or get blood drawn.
