Super helpful, would recommend for everyone with POTS

Overall, I totally love this app. I use it daily as a POTS patient, and it's helpful for pacing, especially to have tactile feedback to let you know symptoms are flaring without having to be looking at a screen at the right moment to catch it. Super useful and absolutely a must-have for people with POTS. Especially pairs well with the FatigueSense app, with TachyMon helping immediate pacing and FatigueSense using TachyMon's more frequent data to better calculate long-term pacing.

I particularly love the initiative to create something to help the (mostly young women) POTS and other chronic illness patients, when medical misogyny leaves us understudied and otherwise without many tools.

I only have very few very minor suggestions, and why I would like them.

1. Ads to use premium features — Like many disabled people, I can't work, so I don't have the money for a premium subscription. A popup such as "This is a premium feature. — Watch ad (effective for one use) — View premium options — Cancel" would allow me and others in similar situations to use these helpful features and monetarily support the app even without disposable income to do it directly, and people who have the money would still buy premium for the convenience and time-saving.

2. Resting rate instead of recent average — Currently, my level 1 delta low alert is -45. With this, I get alerted when intentionally resting to calm the POTS, but any higher amount would be more than the difference between my resting and asleep rates, and would effectively make the setting never trigger. A toggle to switch between using recent average and resting rate would allow using resting during low activity to alert for standing spikes without alerting intentional rest, and switching to recent average during activity expected to be outside of resting range to allow dynamic alerting during varying activity levels.

3. Explanation of recent average — This is a very simple one. Is the recent average using all recordings within a certain time? The last certain amount of recordings? Or something else? Basically just adding a description of what exactly it is, as opposed to "recent average" without elaboration. I like knowing how everything works.

4. Sleep screen — This one may not be doable and might just be how Apple works it, so fully disregard if that's the case. I have my watch set to use a sleep screen during sleep mode, so it first opens to a much dimmer, simple screen showing the time, and further interaction goes to the standard lock screen. This keeps me from flashbanging myself awake with a bright screen if I'm just moving my arms. Having an open session seems to turn this off, and it just shows the much brighter standard lock screen. Not a huge deal as I just end the session and use the built-in intermittent heart rate checks at night or when napping, but it would be nice to be able to use the app's more constant monitoring without potentially disturbing my sleep.

Again, wonderful app and totally love it, even with not having these things. I, as a person with POTS, recommend everyone else with it try this app. Even without the personal experience, I recommend to anyone who needs to monitor heart rate or its changes for any other reasons. Great app.

Amazing!!!!!!

Thank you so much for making this! I have POTs and this is making such a difference in my life. I can’t tell you how much I appreciate this app!

They started charging us 🤬

Works relatively well, however is used to be free to monitor your hr and now they charge for it. Disabled ppl don’t have money. Thx a lot for giving us a free tool and then decide to start charging ppl. Greedy jerk. Don’t we have enough of that in the world?!

Amazing but I want to suggest

I love this app so far. I have POTS and been trying to record my days more organized than just the heart rate app on Apple Watch. This app has helped so much in documenting when my heart rate got too high and low, I do enjoy all the features it includes too. My only suggestion is for symptoms adding in “overheated” just because most of the time that’s my biggest trigger but not all the time. Overall thank you for making this app! It helps so many people. 🥺

Is it really free?

It will not let me start a monitoring session unless I pay for a subscription. I’m reading responses from the all saying that monitoring remains free but it will not allow me to move forward without paying for the subscription.

Life saving

I have POTs and with this it helps me through normal day to day tasks to let me know if I am pushing my self too hard. With out it I wouldn’t have been able to get my symptoms to regulate it self naturally with out meds

No free version

I downloaded this app as a recommendation, once downloaded there is no free version. It shows you what you can get if you sign up for the subscription but that’s it. So disappointing.

Can’t see my sessions in app

I can’t see my sessions in app. Really frustrating

Love

This App and the exports helped me get my diagnosis after 6years of gaslighting. Thank you.

Useful for other rhythm disorders!

I don’t have POTS, but am having tachycardia spells related to another heart condition and this app allows me to document them then record an ECG on my Apple watch. So glad I found this!

Thank you 🥺

To the developer who has POTS, thank you.
I’ve been using this app for about a month now and it has been so helpful. I know what my personal thrust holds are, and I’m aware of which heart rate is going potentially take me out… So it is so nice to be able to attempt to live in normal life and trust that the watch is going to alert me when needed. I no longer have to carry a pulse ox around with me. It’s just made it so much easier to live with a condition that’s not easy to live with.
I had to reach out to customer service once and they got back to me almost immediately and guided me through my tech issue with ease, patience and kindness.
The only small drawback is, I have noticed that the app is about 2 to 5 beats lower than what my pulse ox and BP cuff say. But that’s a non issue.
It is really affordable and will great for providing my cardiologist reports if necessary.

Love love love

My doctor will really appreciate the data!! I accidentally forgot about it during trial. Best adhd tax ever. 😂

Terrific

Only thing that would make this app better is when symptoms high notifying emergency contact in case of a fall

Absolutely Accurate!

I had a stress test recently and had the hospital verify that my TachyMon app was accurate. After 3 months of monitoring for POTS and SVT, it was awesome to hear it is accurate down to to the beat and moment.

POTS

I have been searching for a good POTS tracking app and this one is great!! The only other thing i would want on this app is the ability to add your own symptoms, cause the ones on there aren’t all i experience. I would give the app a 4.5/5! It’s so nice to see the exact time my episodes occur and how long they happen for! I am a subscriber and am on the free trial right now, but i keep on keeping my subscription because it’s not too expensive and it’s helps a lot more!!

Annual premium renews in June 2026, but it’s acting like I haven’t paid a premium fee.

Had this for years now, I paid the annual and it’s not up till June 2026. The app won’t let me use the features on the watch. Says premium fees required.

I remember when the app maker wanted to help his family member and this was free .. why are my charges for the services not working.

game changer

incredibly helpful for pacing and tracking symptoms with POTS. i don’t faint (usually) but this app still helps me manage my symptoms and keep myself from pushing too hard. only constructive criticism i have is that it would be nice to have live activities and widgets for the phone, for people who track using a bluetooth monitor. please keep supporting this app!! i’ve only been using it a short time but it’s already been such a boon!

Please add a feature

While I do like this app a lot I also think being able to track hrv throughout the day would be very beneficial besides just hr

I love it!

I use this app everyday pretty much it helps me manage my pots and helps me have numbers to share with my doctors!!
I think the subscription is very fair and worth it, I hope one day you guys make a lock screen widget for the phones though so we can see the session without having to look at the watch or in the app. I also think that having it send the running session and notifications to a contact for when you’re out and about with family or a partner would be awesome!! Love the app though!

POTS POTS POTS

I kept hearing about TachyMon on my POTS Facebook pages. It’s AMAZING! If you want to know if your HR goes up by 30+ BPM upon standing, this app clearly shows it. I had to get off Midodrine and Mestinon for a TTT and it was glaringly OBVIOUS which days I was off my meds. I like that I can add notes to log these things. Lastly, I thought I was going to have to upgrade my Apple Watch version 6 but TachyMon does not kill my battery. I use it for 13 hrs a day and my watch is still running when I get ready for bed. Download it, you won’t regret it!
