TachyMon was created by the developer for his niece Alex, who was diagnosed with Postural Orthostatic Tachycardia Syndrome (POTS) in the fall of 2021. POTS seems to be an increasingly common diagnosis, especially for young women. People with POTS often experience fatigue, brain fog, rapid heart rate increases and other symptoms. Alex was experiencing frequent fainting (syncope) and we noticed the fainting occurred when her heart rate increased rapidly, or when her heart rate reached a certain absolute threshold (150 BPM in her case). Alex finds that the TachyMon alerts help her to sit or crouch down when her heart rate is elevated, and this helps her to avoid fainting, and to feel a bit more in control of her POTS.

It is a simple, but specialized app, and we hope it may help others with POTS, or people in other situations when it may be useful to monitor heart rate changes.

APPLE HEALTH
TachyMon integrates with the Apple Health app. TachyMon stores workout information (including heart rate) with the Apple Health app.

## TachyMon Reviews in United States

### *---- "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.
-- Mommymandy2, 2026-06-19

### ***-- "Can’t see my sessions in app"
I can’t see my sessions in app. Really frustrating
-- RJP2002, 2026-06-17

### ***** "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!
-- Joeyboy204, 2026-05-30

### ***** "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.
-- Allieb868, 2026-05-09

### ***** "Love love love"
My doctor will really appreciate the data!! I accidentally forgot about it during trial. Best adhd tax ever. 😂
-- jorychi, 2026-04-05

### ***** "Terrific"
Only thing that would make this app better is when symptoms high notifying emergency contact in case of a fall
-- Carla.1976, 2026-04-02

### ***** "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.
-- TimberlakeDawn, 2026-04-02

### ***** "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!!
-- POTSgirly, 2026-03-27

### **--- "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.
-- audie king, 2026-03-24

### ***** "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!
