Wearable Comparison
The Short Version
WHOOP, Sonar, and Vora all claim to help you understand your body. They are not direct competitors. WHOOP is a dedicated hardware platform for recovery and strain. Sonar is an aggregator app that pulls data from your existing wearables and turns it into health scores. Vora is an AI coaching layer that uses your data to decide what you should do next.
Most people who get serious about health end up using two of these three, not all of them.
WHOOP — The Hardware Platform
WHOOP gives you a screenless band, a 24/7 sensor, and an app built around a tight recovery and strain loop. It is opinionated, polished, and excellent for athletes who like the daily recovery percentage as the center of their training decisions.
It is also a closed ecosystem. WHOOP wants you to wear WHOOP and use WHOOP. It is not designed to interpret your Apple Watch or Garmin data alongside its own.
Sonar — The Aggregator
Sonar takes a different approach. It does not sell hardware. It connects to Apple Watch, Garmin, WHOOP, Oura, Fitbit, Polar, Strava, Withings, MyFitnessPal, Peloton, and more, then computes its own Recovery, Sleep, Strain, and Nutrition scores from the combined data.
This is genuinely useful for people who already own multiple devices. Instead of switching between four apps to compare a Garmin recovery score with an Oura readiness, Sonar consolidates the picture.
What Sonar mostly does not do is decide for you. It is a sophisticated dashboard, not a coach. You see the score. You make the call.
Vora — The Coaching Layer
Vora overlaps with both. Like Sonar, it integrates with many devices, including Apple Watch, Oura, Garmin, WHOOP, and Fitbit. Like WHOOP, it produces a daily Health Score that summarizes readiness. Where it diverges is the next step.
Vora is built around decisions. The score is the input, not the output. If your HRV is suppressed, Vora adjusts your workout. If you are at peak readiness, it pushes intensity. If nutrition is off pace, it shifts your day. The system writes the plan.
How They Fit Together
The cleanest stack for a serious user is one device and one coach. That is usually Apple Watch plus Vora, Oura plus Vora, or WHOOP plus Vora. Sonar adds value if you own three or more devices and want a single dashboard to interpret them.
Stacking WHOOP and Sonar is possible, but you may notice that both produce overlapping scores. Stacking WHOOP and Vora is more complementary because Vora is decision-making, not scoring.
Pricing
WHOOP runs roughly $199 to $359 a year and includes the hardware. Sonar Pro is around $50 to $230 a year depending on plan and region, with a free tier. Vora is $12.99 a month or $89.99 a year, with a free tier and no hardware requirement.
Sonar and Vora are both software-only and significantly cheaper than WHOOP. They are also the two products you are most likely to confuse, because both claim to be the brain across your wearables.
The Real Difference
Sonar will show you that your recovery is low. Vora will tell you to swap today's lift for mobility and shift the heavy session to Friday. Both products are useful. They are answering different questions.
If you want to see your data, Sonar is excellent. If you want your data to change the day, that is what Vora is built for.
Who Should Pick Which
Pick WHOOP if you want dedicated recovery hardware and a coaching culture built around it. Pick Sonar if you own multiple wearables and want one dashboard to reconcile them. Pick Vora if you want recovery, workouts, nutrition, and daily planning decided by an AI coach that reads whatever wearables you already have.
