Feeling odd

A while ago I was feeling a little odd. I used your heart app and could see that my heart was missing beats and was able to call paramedics who came and dealt with me. Brilliant

All it wants is money

Waste of time. Need to pay to use.

Mostly accurate

I use this app to track my waking heart rate and the times when I exercise. Most of the time, it’s easy to use and to get an accurate reading. Sometimes, it can read that my finger is blocking the camera lens, but it won’t give me an accurate reading. Other times it has difficulty locking onto my finger at all. So, mixed review.

Slow and Hard to Work With

I do think the app is organized, however it’s SO difficult to work with and it takes like ten tries each time you want to record your heart rate. I tried using this for a class, but by the time it recorded, my heart rate would lower after a workout. It’s just not reliable and I’ve talked to some of my friends who used this app for the same reason and they had the same issues with it. Do not recommend.

Poor signal quality?

I will watch as the app measures my heart rate and stays in a very narrow range as I hold my finger over the camera for however long. It seems perfect, but then it just says “poor signal quality” with no other explanation. The signal quality was in fact not poor as I watched the data being collected and it seemed to be very consistent throughout the entire process. I need to use this app to properly measure my heart rate, and it is not doing what it claims to be good at.

Doesn’t work

Every time I used it, it measured the heart rate for quite a long time. Then, at the very end, it said “poor signal” and terminated. This is a terrible product. I deleted it, and I don’t miss it at all.

Didn’t work

Every time I tried said poor signal and couldn’t do a reading no matter how I adjusted the light and camera. Other similar apps worked much better and actually worked. Disappointed.

Makes it simple!

I enjoy checking my bpm with this makes it so easy

Great for measuring heart rate:)

Scam

Claims it’s free, demands money for use after download.

No blood monitors

I’m enjoying the app but the only issue I have is that there is no blood monitor

Great app

Woke up with racing heart, helped monitor the situation

Ничего не измеряет

Ничего сверхъестественного не делаю, не двигаюсь, палец проложила, он мерит, показывает цифры а в конце оказывается что сигнала не было и просит заново. А сразу типа не понятно что сигнала нет? И как же тогда измерение шло? Просто убивает время и не дает результата

Endurance score bug

The endurance score is no longer working as it did. Seems to be fixed.

Perigo para o bolso

Pode até ser bom, mas testes gratuitos são uma arapuca. Você concorda, começa a pagar depois de uma semana e se esquece de desativar

I like the app but I don’t like it

You literally got to sit still no movement period or it will not register. You guys need to fix that issue.

Cobrança

Foi realizado cobrança no momento que foi iniciado, mesmo constando que os primeiros 3 dias seriam de testes.

Prático

Eficiente!
