Polar never disappoints a minimalist athlete clarity of mind

OH1 is quite a device Polar never disappoints a minimalist athlete

Amazing 2026

I started using polar back in 2008 and continue to do so on 2026. Polar sports watches are a cut above other brands for serious health and sports people.

Lo mejor

Resistente y precisa

GPS always inaccurate

App is fine, does the job. My watch is so awful and always has been, its gps is incredibly inaccurate, it got stuck on 4.93k for 8 minutes on my run this morning. Complete waste of money and I’ll be saving up to buy a garmin

Broken

Doesn’t work with new device.

Excellent produit

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.

Does not work with H10

This app says it works with the H10 heart rate strap, and it links up, but then it only records data while the app is open and the phone is unlocked. Use their other app: polar beat.

Flow flows

Works for mostly what I want. I can track, edit and review my activities as needed. I would like to be able to have expanded editing functions for run programs, such as hold/pause a program (rather than holiday) and more flexibility on modifying planned activities but hopefully that eventuates.

Inaccurate distance

There is a point on my usual route that is almost exactly 2.0 miles. Two days ago was my first use of the app and it labeled that point as 2.05 miles. Okay, cool, I’ll live with that. Yesterday the app labeled the point as 2.25 miles. Whut?
Today I tried walking around the courthouse, a known lap of 0.22 miles. I did the lap four times and Polar said the total distance was 1.05 miles. Sheesh.
Buh bye.

Dated app, useless chart

I use this to monitor my heart rate throughout the day. Since I had been diagnosed with myocarditis. The chart is useless and not very clear at all. Data shows no real insight. I had to buy a smart ring to get useful information. W

Background activity

For the last few days the app seems to be using hours of background activity every day. Battery settings says Polar Flow has used 50%…

Polar flow

Have used Polar since early’80’s & always been impressed with all the features.
My Sports include Rowing & Cycling. I have the backup to be very good.

Good but could be better

This app has all the necessary features and information but, it’s UI navigation and visuals really needs some polishing. Details can be hidden and not easy to dissect! Polar please revamp the app with a clean modern look. On a positive side the data is very accurate and reliable.

Muy recomendable

Bonne application

L’application est assez facile d’utilisation, ce qui est agréable. Par contre tous les sports ne sont pas représentés et pour moi il manque notamment la nage avec palmes, masque tube. Rien ne correspond et le métrage lorsque je me déplace ainsi en mer n’est pas fiable.
Je me pose des questions également sur le Pilates, qui demande pourtant précision et effort, mais au bout d’une heure, il semble que je n’ai dépensé que quelques calories et très peu en pourcentage de ma journée… Peut-être des améliorations à apporter de ce côté là ?
Il n’y a pas le CrossFit non plus. Dommage.
Pour tous les autres Sports que je pratique c’est très bien. 😍

Background activity issues

The latest update seems to be rinsing my battery with background activity. Not sure how to stop this. Any advice would be great.

Can’t find real time heart rate display with Polar H9

I used to use a Polar chest strap with a wrist display that showed my heart rate in real time. I can’t find anywhere in this app that I can get that information. I don’t want a coach, I just want to see my HR while using the chest strap and transmitter! Too late for me to send the H9 back …

Discreet

Unlike Apple Watch it stays in the back ground

heart rate zone

Where did the heart rate zone chart disappear from the Polar Flow app? Previously, you could see which zones you were training in, for example, for three days—your current result. After the update, nothing is visible.
