Open Source Heart Rate Monitor App

This watch has some many useful function including calling for help if you fall, heart rate monitor and other health app. I feel like Dick Tracy when I speak into my watch using the intercom or answering a phone call.

An essential item if you ever want to do any open heart surgery on your electronics.

Great that he can monitor his heart for afib and take an EKG whenever he wants.

This is the third Apple watch I've owned. It seems that this watch works a little faster than the others. I use it as much for health issues. The Heart Rate monitor picks up the same as my belt. This is an improvement over the past watches. The Blood O2 is good, particularly now with Covid as lung function is an indication of the virus. All in all it's a worthwhile purchase.

This watch is absolutely perfect for my husband and I. We aren't sports fanatics but need to keep track of heart rate. We walk, ride bicycle, and treadmill. This watch tracks it all. Best of all, we only have to charge once every 3-4 weeks. Just wish I could get another one in the white rock color.

I put Gargoyle open source router software on it. It can do so much now. It's a snappy router.

I love this monitor. It was easy to set up and the instructions were prefect. I'd buy another one in a heart beat!

We had much trouble converting our video source and getting the frame rate we needed. The less expensive converters would just not do the trick. Out of the box this worked perfectly and immediately solved our problem. It is a simple device and cicuitboard, but the software on the chip is worth the money if you need it!

Early adopter here of the 42” A90K - bought sight and review unseen in August 2022. I put it through the paces setting up all of the inputs with non-invasive settings, and did not have to adjust calibration settings at all from the factory settings for what I thought looked correct. Fantastic contrast without crushing levels - really brings out the best (and worst) of whatever the source is. HD and UHD Blu-rays look astoundingly good, and Dolby Vision implementation looks spectacular. Broadcast OTA looks great too, and streaming internal apps and external (Roku) all good. CATV low bit rate (decompression) in direct comparison to the same channel OTA you can really tell the difference. It is unforgiving of bad or low quality sources, but in the same turn will let your great stuff shine. The remote is nice in hand, missing number buttons but otherwise easy to use. Soundbar handshaking works without issue, and internal apps with the built in wireless are great, including the Bravia Core high bit rate streaming you get for free, along with 10 credits for purchasing titles there. Downsides: almost none. I bought an OLED for true black and near-black detail and this is great. Sources dictate what you get here - the set in its default calibration will be true. I do not like how there is no ‘display’ info button on the remote, and even trying to use an older ‘display’ button from a previous remote only shows time detail. The missing info that is useful to me is resolution, bit rate, frame rate, interlace/progressive, audio channels, etc. which is barely existent and mostly unavailable to the user. I miss having it to be able to check what the set is doing and seeing as source. It’s expensive but you realize the value of the purchase with a premium presentation of high quality sources.

i use this as a second monitor and couldnt be happier. tHIS MONITOR PERFORMS JUST AS YOU WOULD EXPECT IT TO. THE REFRESH RATE IS INSANCE AS WELL. VERY GOOD PRICE
