Alex was experiencing frequent fainting, and her family noticed the episodes often followed a rapid rise in her heart rate. She wanted a heads-up the moment that started happening. Alex uses TachyMon's alerts as a cue to sit or crouch down when her heart rate climbs quickly, and she finds the app helps her feel a bit more in control of her day. It is a simple but specialized app, and we hope it may help others with POTS, or anyone who wants to be alerted to changes in their heart rate.
