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.
