Personal details

It might be there , but I'd like to be able to just click onto my name to keep easy records. I said it might be there but please remember this.. One day you will be in my shoes. Older people don't understand how things work. Their eye sight is generally quite poor. Technology is a catch up process and that's why I say things have to be more than obvious. When you make a program , take to some old codger and say , eh mate have a go at this. Don't you help him by explaining it. He or she has to go from the start. I'm pretty much ok at things as i used to do some programming, Try that with a general labourer. When you retire the ipad becomes a new world to us. A great world.
I once told a shampoo company something similar . My question related to marketing their product to clearly indicate the difference between shampoo and conditioner. When I take my glasses off I often wash my hair with conditioner. Also consider the blind.
I sure you get my drift. I think your program is ace. I'm a first aid instructor and can see its merit.

It would be good to have any murmur identified so that the client can have it closely checked out by their Gen Prac so this would give a clear value for the app

Thank you

Regards. Pete

I really appreciate this free app! My cardiologist has checked my heart rate at the same time and was impressed with the accuracy ( I know it’s not a 100% medical tool etc but it’s great it works for me ) I have told many friends and family members about it too and they also have been happy. Thanks Cardiio

Unsuitable for those outside "normal"

The app does not have a way to record irregular heart rates/arrhythmia, especially during severe tachycardia, including SVT events. Instead, it interprets as poor signal and does nor offer an option to save the waveform. Wouldn't have paid had I known.

Edit: Had to edit review to reduce the rating. The new look and its update are pretty bad. The app badly needs a feature where user gets an option to save the reading and waveform even if the app "thinks" it is wrong. It shows the waveform but decides not to save. This is useless.

Also, with the exercises, there is no user flexibility in choosing what kind of exercises you wish to do and for how long you want to do them. There are some exercises, such as jumping jacks, step on stool, side plank that I cannot do due to some injuries and medical problems, but I have no option to simply skip these and move on to the next. I have to wait for the annoying voice to finish making me wait until I check out the next. Ain't nobody got time for that.

I had high hopes with this app, but I now regret paying for this app.
