While I use my Polar watch for some sports, I use other devices and sources for other sports. This means I need multiple Apps and don’t have a single integrated view of my training unless I resort to things like Strava - which I really do not like. I’d also like to see more direct data and analytics around training and recovery. The high level workout level categories are sort of cute, but real numbers are easier to use for serious training. ### 2/5 — Not overly joyed *2026-08-22, version 7.36.3* It’s quite cheaply made and won’t automatically link to Strava. The screen isn’t very sensitive so trying to swipe isn’t reactive enough. Stopping the watch after an activity and having to hold for the counter to tick down isn’t great either. Although the watch is pretty and looks great. It is accurate in distance tracking and GPS. ### 3/5 — Great app with some fundamental cross platform limitations *2026-08-22, version 7.36.3* Really like the device and the app and the working. Good job. My issue really is its ability to sync full data with Apple health. For example it only shows the sleep length, not the different stage (light, REM etc). Unfortunately it falls at the last hurdle. ### 3/5 — It used to seem better *2026-08-20, version 7.36.3* Will miss data that I used to get from laptop downloads and It shouldn’t comment on today’s status until all the day’s hours have been accounted for. Disappointing. ### 4/5 — Step counter is off *2026-08-19, version 7.36.3* I love the look of it - it’s sleek . One con is the step count seems to be way off. I wish I could also get a graph of my progress where I can include several months, not just weekly . ### 2/5 — Glitches and doesn’t record sleep & exercise *2026-08-18, version 7.36.2* I’m running into a lot of problems with it ### 2/5 — Chastising comments on fitness levels *2026-08-16, version 7.36.2* In the same day I was told to rest because I slept poorly and if I didn’t keep training harder that I would lose some of my fitness. I am about to break from years as a loyal Polar user because as someone in an active eating disorder who trains anywhere from 2-5 hours almost every day, it messes with your head to see the app telling me I’m not doing enough. Dangerous messaging for people and encouraging them to over train. ### 4/5 — Biometrics help measure trauma symptoms *2026-08-15, version 7.36.2* I am grateful for the daily metrics that help me to manage my activities, so I can avoid crashes. ### 2/5 — Record function? *2026-08-11, version 7.36.2* When is the record to sensor gonna be available? It’s been too long… ### 4/5 — Perfect nearly *2026-08-08, version 7.36.2* The polar flow is fantastic I like wearing a real watch so I can wear the flow on the other wrist all the data is there just need apple health to except permissions I have to manually input everything every morning bit of a faf but doable once that is done so I don’t have to manually do it it will be the perfect tracker ## Most critical reviews (10 lowest-rated) ### 1/5 — Force you to give up privacy *2026-08-23, version 7.36.3* I paid for the sensor. The app is “free” except that the only way it works is if you agree to let Polar collect, sell and do whatever they want with your data. This should be criminal. I returned the H10 and bought a Garmin because of this. ### 1/5 — Set up is unsatisfactory *2026-08-19, version 7.36.3* Software for set up is very clunky, difficult to set up with phone. ### 1/5 — Update *2026-08-19, version 7.36.3* Very frequently I have to reset the watch and as a consequence lose all the history Very disappointing ### 1/5 — Glitches *2026-08-16, version 7.36.2* This app always just randomly stops finding my polar sensor. It does this every month or so. I kept thinking it was the device until I replaced the device and same thing happens. Then I used the polar beat app and it works perfectly fine. This app sucks. ### 1/5 — I want to continue using the app *2026-08-15, version 7.36.2* But the button does nothing ### 1/5 — Is Garmin Better? *2026-08-13, version 7.36.2* Needs a lot of improvement. Clunky Often fails to sync. ### 1/5 — Bad *2026-08-11, version 7.36.2* In a nutshell data is inaccurate, wouldn’t recommend buying ### 1/5 — Thanks for brick *2026-08-11, version 7.36.2* I refuse to consent to having my personal data processed outside my country what’s the refund process? ### 1/5 — Needs an update *2026-08-07, version 7.36.2* The polar app is dated and needs updating ### 1/5 — App disconnects *2026-08-07, version 7.36.2* The app disconnects alot from the watch, and it acts like I have to log in to the app every few days. It’s exhausting ## Most praised reviews (10 highest-rated) ### 5/5 — Awesome *2026-08-24, version 7.36.3* Still loving and even better with Polar Grit 2 ### 5/5 — Great app *2026-08-21, version 7.36.3* Lovely functionality between watch and app ### 5/5 — They keep it working. *2026-08-17, version 7.36.2* I love the watch. The app is the cool side kick. Polar keeps the app updated. The watch is still working after 2 years. 1000 miles a year have been logged. The battery is still strong. The band needed replacing after a year and a half of heavy use. Keep running! ### 5/5 — Great app to track your training *2026-08-16, version 7.36.2* I’ve been using the app for over 5 years tracking my activity and sleep. It gives in depth information on heart rate, sleep and fitness level. I track my exercise routines including running, biking, rowing and strength training. ### 5/5 — Fantastic Watch *2026-08-15, version 7.36.2* Very user friendly great features! ### 5/5 — Excellent produit *2026-08-13* J’ai choisi une montre connectée Polar afin de pouvoir avoir accès aux activités LESMILLS que je pratique quotidiennement en plus des autres activités physiques. Tout est bien détaillé, aussi bien le suivi sportif que le suivi qualité de sommeil. Je découvre petit à petit les différentes fonctions. Je trouve dommage que la montre se décharge rapidement mais le chargement est assez rapide. Par ailleurs, j’ai été obligée de racheter une autre montre Polar Unite car l’ancienne (moins de 3 ans) a eu un problème de fonction de l’écran tactile qui ne fonctionnait plus (impossibilité de changer l’écran, d’activer mes activités, etc…). Est-ce normal pour une montre relativement récente? Toujours aussi contente de ma montre qui répond exactement à mes attentes. Il me semble que la présentation des données a changé car j’ai l’impression que certaines données sont plus compliquées à trouver. ### 5/5 — good *2026-08-13, version 7.36.2* good ### 5/5 — Amazing App if you can find its features *2026-08-10, version 7.36.2* Polar flow is jam packed with useful features few others have. One example to trim your workout data and many other useful reports but it’s a maze to find sadly. App it poorly organized needs a UX expert to cleanup. Clearly no marketing team. All backed by exceptional devices when it comes to accuracy for high frequency monitoring and others. Easily a 5 star but without the cleanup 4 ### 5/5 — Polar flow *2026-08-09, version 7.36.2* The app is great unfortunately the program used to be free for training now you have to pay for it as a subscription. ### 5/5 — Easy and simple *2026-08-07, version 7.36.2* Super easy to link to Strava --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
