This was a fantastic resource for those who needed to continuously track their heart rate. It now does little more than the basic heart rate monitor ihealth offers. Most of the features have been locked behind a SUBSCRIPTION paywall. It’s absolutely insane how developers don’t understand how many more people would be willing to pay a one time fee for apps and how much of a turn off it is to try turn this into a subscription service.

graphs are now behind a paywall, the app is pretty much useless as you cannot see how rapidly your heart rate rose or dropped without paying a MONTHLY FEE! shame on you for trying to profit off of the disabled community in this way.

I have had POTS symptoms since I was around 13, but only recently took the time to take it more seriously and seek diagnosis and ways to minimize my symptoms. I started with the Oura Ring and while I love it for other reasons, this app by far is better for monitoring POTS levels and heart rates. I love that I am able to monitor in real time and also download any data and graphs I want to share with my cardiologist. It is also validating to see your symptoms you’re feeling in a way that is less easy to minimize. My only wish is that the delta would have 2 indicators - 1) against your recent average, which is currently represented but also 2) against the average resting heart rate I highly recommend this app to anyone trying to learn more about their POTS. I love it!

I don’t normally leave reviews but I want to support this developer in whatever way I can. The default HR log in apple health doesn’t show the rapid jumps in heart rate, so it was useless to my doctors. This app is exactly what I needed! It’s the best measure of how I’m doing day to day. -Minimal battery drain! The default apple HR monitor only “checks in” every few minutes, but this app is measuring HR nonstop. This app does use slightly more battery but it still lasts me the whole day. It’s surprising how little it takes. -One nitpick I have is that it will log the HR difference between ending the previous session and starting a new one. I wish there was a minute for the μ rate to adjust in a new session before it sends alerts. I am so glad this exists, it’s honestly brilliant. Just alerting for every little dip and jump in HR would be impossible and impractical, but the math behind this app is what makes it work! The concept and execution are both great. Thank you for creating this!

Even the basic features are (sometimes literally) lifesavers, and the recent updates and subscription options make it clear that app developers care about users. Thanks for all the continued improvements!!

I was really excited to try this longterm HR tracking, but I am completely unable to download this app on my Watch. It’s useless to me. Wish I knew that before I purchased a year long subscription.

Literally the only free feature is that it’ll give you haptic feedback when your heart rate goes above a certain rate,it’ll log your high, low, and average heart rate during a time period, and it has a very rough heart rate graph. You can’t track symptoms, no detailed graphs, you can’t export it, you can’t use a Bluetooth heart rate sensor. It’s helpful, but barely, and you’d likely be better off installing a free app with more functionality.

You want to hide features that used to be free behind a paywall? Fine. It’s terrible, but FINE. At least allow people to buy the rights to use your app without doing so with a subscription. You know, like how we used to buy software? The majority of the people using this app are disabled in someway, so they probably don’t have a ton of disposable income. I despise subscriptions and the fact that companies keep thinking that they can charge people $20/year instead of just charging for the software and either updating it or releasing a new version if it’s that big of a change makes me absolutely furious. What’s especially irritating is that there are probably better apps charging $20/year if you’re really willing to spend it too! Apps with more features that aren’t nearly as glitchy.

This was a great app until a month or so ago. Loved it for at least a year. The latest update ended up removing it from my watch and I had a hard time getting it back. I should have considered that a sign but I kept tying because I really loved the app. I tried off and on for two weeks. After a day or two of it back on my watch, it froze on ending a session. It did that a few times before the update but always fixed itself after 30 or so minutes. This time it didn’t fix on its own, and would hinder the health app built in from checking my heart rate. It changed the screen on my watch back to the default screen. Everything is fine now because I had to delete the app.

I’ve had this app for 2 years now and it was a lifesaver for my POTS and the idea of the app was with good intentions and pure genius! Loved this app but will now be deleting the app. It’s really f**cked that they now require a subscription to use certain features that I used to use to give to my cardiologist to help monitor my condition. Taking money from disabled people for your own gain isn’t cool man.. make the app completely free again and then I’ll redownload… until then I don’t recommend unless you have the money to afford a monthly subscription for things that used to be free. In my opinion it isn’t worth it and there are other free apps out there. Disappointed in TachyMon tbh, this was unfair and unexpected..
