Great watch Poor App

Love the watch. It’s light and tracks well. The App is not great. Constantly having to Sync the watch and reset every few weeks.

Polar Flow doesn’t flow

I had the Polar Beat and it was fantastic. User friendly.
This one is more complicated and you can only e-mail them for help.

It’s okay

The app is technically capable. Really annoying is it asks for a review EVERY TIME I SYNCH my watch to the App. Even though I’ve already written one.

The latest watch interface is clunky - you require 4 individual finger presses to start a training session! Far too many.

Ending a session is clunky too. I had to press the end button continuously - as it would not respond - it the restarted the watch completely & I lost my whole days training session- hugely frustrating!

Started strong, now not so much

Loved polar products. Finally sprung for the vantage v3. Their HR accuracy won me over. I got a solid 18 months out of it, but this last update took a turn for the worst. I can deal with a lot, but I'm all about tracking my HR. Since the 6.0.18 update, V3 is reading my rate as bradycardic when I'm 2x, sometimes 3x above. I'm starting to look at Apple Watches. Bummer.

Sync issue

Sync doesn’t always sync , leaving data unrecorded.

Too Many Problems

To many problem with the app sync with my watch.

Easy comfortable and minimal

I am obliged to give four stars to my Polar Gen 2 just because it frequently has connection issues. Most of the time synching with delay and is losing the connection easily. If polar could work more in these issues, it will be way better than Whoop and other similar sensors out in the market.

Sync

App doesn’t get synced with the phone automatically

Pool laps doesn’t work reliably on my Polar Vantage M.

My watch is not recording the laps in the pool. It stays at 0m the entire time

Could be better

Wish it told battery %

Grit X2 Pro

The more I work with the phone app and watch, the more I learn about all the data and capabilities below the meek interface. The app is really great and I’m so happy with the watch!

Room for improvement

The app is not consistent.

Great app

Very cool app. Easy to navigate. And is improving with each new update. Keep up the good product development

Great!

It ‘s been good and reliable over the years! I like the multiple sports options. Battery life of polar is great and fast charging. The layout is nice to use. I tried another platform and went right back. I hope Polar will keep up with competition!!

Great update !

Widget works now and the interface is great ! Keep pushing Polar !

Poor user experience, locked data fields

If you’re only interested in a step or sleep tracker, it’s fine.
But the Polar loop is incredibly poor at tracking heart rate for first 10-15 minutes of any activity, providing terrible data metrics. Until the Polar Flow app allows for unlocked data fields for manual updates, including calories and average heart rate, this is not a useful combination.

adam

awesome watch and pretty good app. recommend have presets for the watch face. one each for work, training and general use. thumbs up for excellent product.

This pop up

The app is fine but this ‘are you enjoying polar flow ?’ Pop up is, ironically, making me hate the app.

Polar Grit x2

Great app to accompany their watches. However, it doesn’t sync with my wahoo and I’ve had to use Run Gap to transfer the wahoo rides to the polar flow app. Polar really needs to update their app to make uploading other workouts to it easier. Apart from that I can’t fault the watch. It’s easy to navigate and use. I also calibrated it with my wahoo HRM chest strap and it showed exactly the same bpm.
6/9/26 update
Heart rate drops out while exercising, nightly sleep features don’t work ANS, skin temperature. I can be half way through a workout and the heart rate just stops working. I’ve tried changing the settings, cleaned the back of the watch, moved it up my wrist slightly, tightened the strap and nothing seems to work. In reflection I really probably shouldn’t have bought it.
