I trust Polar
I used a Polar chest strap heart rate monitor for more than a decade: it was flawless.Now I wanted a fitness tracker specifically for sleep tracking: this device seems very accurate, although I am going by what I see and how I feel (never a good scientific method). I have not tested against a trusted sleep measurement benchmark.I can say more precisely that the heartrate monitoring in this device is very accurate when tested with the new Polar H10 chest strap: before pairing them, they provide virtually identical heart rate readings.Also, this device pairs nicely with the Polar Flow app, so: as long as I use my A370 during a workout, all my sessions are logged accurately, even when I am not wearing the H10.If I could make one suggestion to Polar it would be this: a longer battery life would be appreciated. Otherwise, I am good with this fitness tracker. To date I like everything I’ve tried from Polar.

Accurate heartrate but short battery life
Heartrate reported by the A370 app matches quite well with the heartrate from a Polar H10 Chest Strap monitor, if the watch strap is tight. In comparison, the Fitbit Charge 2 that it replaced would usually show my heartrate dropping to ~ 70-80 bpm as my actual rate rose to 130-160 bpm, no matter how I adjusted the strap. So did the replacement Fitbit.The Polar A370 only reads heartrate every five minutes to extend battery life unless continuous heartrate or a training activity is selected, and it does not automatically detect training activities. Battery life is shorter than with the Fitbit, and especially short when heartrate is read continuously.The Polar Flow app doesn’t give as much data as Fitbit (no stair flights, rudimentary and inaccurate sleep monitoring).When driving or cycling, the Fitbit sees bumps in rough roads as steps. I can’t easily tell if the Polar A370 has this problem as it doesn’t provide data on when steps were taken.

Great product, good quality
This is a great watch/monitor. Its well built and works very well. Connection and apps are also very well designed and gives you a great indication of how your workouts or even daily movements looks like.

It’s OK just too “in the past”
It does exactly what you need just not updated for this type of world in the sense of new watches now-a-days. If you want a basic one soley for excersises then this is the ONE!

Very satisfied
Absolutely love this watch. It does everything I had wanted to it. I also pair it with the H10 monitor but on days when I love forgotten the H10 the watch itself seems fairly accurate. Love the colour display and that it’s water proof, I’ve gone swimming with, but I must admit I didn’t actually try the heart rate underwater. When paired with the app it gives great insights into your workout. You can look back on the graph and see a correlation between heart rate and exercises. It also connects to the GPS on your phone so if you’re running/biking/walking you can overlap the heart rate with speed and the map of your route.

Great heart rate monitor watch and activity tracker!
This is a great watch! The colour is as shown, but you are still able to change the bands. The heart rate monitor is very reliable, but I believe wrist heart rate is just not as accurate as chest heart rate.The sleep tracker is a very neat feature, and I did not even realize that I could receive notifications from my phone.As a runner, I highly recommend this watch!

睡眠の測定を目的に半年ほど使っています。初めての活動量計です。4時間未満の睡眠にはsleep plusでの解析はしてくれないそうですが、測定してくれた分の解析結果を見ると睡眠の調子がわかって面白いです。歩数計や心拍数も問題なく使えていますが、比較対象がないので正確性はわかりません。時計はいくつか表示パターンが用意されていて、デザインによっては色を変えることもできます。時計表示されている画面を長押し(3秒くらい、長めです)するとパターンが出てきます。スマホアプリ側で設定した時間にアラームとして振動させることが出来ます。しっかり振動してくれるので朝便利です！設定時間をいくつか出来るようになると嬉しいんですけどね。充電は3日に1回くらいで、たまにファームアップの確認でPCに繋いでいます。スマホアプリもPCの方でも見やすいです。一度使い方で電話問い合わせをしたのですが、日本人の方でとても丁寧に対応してくださりとても嬉しかったです。

Genial reloj, te indica la calidad del sueño, los pasos que das y tiene 3 niveles para el tema del ejercicio si lo haces de 1 a3 veces por semana, de 3 a 5 veces o toda la semana.Te da avisos de llamadas, mensajes, además te da tracking de ti ejercicio diario, cuantos pasos o cuánto tiempo te falta para completar tu meta diaria.Gran reloj que superó mis expectativas!!

心拍計としての精度も高く、充電の頻度も風呂の時間など外したタイミングで充電すれば十分。日々の活動量と心拍データなどを記録したいなら最適かと思います。また、心拍計としてサイクルコンピュータとリンクさせるのも簡単ですので、サイコン用の胸に装着するバンド型に違和感ある方にもおススメです。ただ、普段は腕を下から上に「時計見るぞ」って動作をやや大げさにしないとスリープ状態から立ち上がっての画面表示がされません。この辺は普通の腕時計から移行した時にはなんとなく違和感あるかと思います。慣れでしょうが。本体も丈夫そうな感じですが、バンド部分をおさえる部分がゴム製で肌にくっつきやすいです。汗かく時期だとかゆみが出たりする可能性は否定できません。

早々に届いた品物を開けてみると、綺麗なA370が入っている。これ、中古なの？箱には入ってないので中古なんだろうけど。とにかく、スマホと同期させてみたらバッチリでした。ありがとうございます。

心拍計機能を求めて買いました。心拍数の測定はかなり細かく正確で満足です。グラフも見やすいです。画面表示は、結構しっかり手を振るかボタンを押さなければ出てこないのが惜しい。タッチで見えるようになるといいのにと思います。睡眠測定は、途中の覚醒とかが少し不正確です。同期は、パソコンとiPadとはすぐにできましたが、スマホとのリンクがうまくいかなくて、今調査中。ケータイの方の問題もあるみたいですが。
