Why this app was built
I got COVID in 2023. I didn't expect my life to narrow the way it did. Suddenly, everyday things came with a cost. A short walk. A conversation. Even thinking too hard. And every time I crossed an invisible limit, I paid for it with days or weeks of worsening symptoms. One thing became painfully clear: pacing wasn't optional. It was survival. Not pushing. Not crashing. Learning where the line is before you cross it.
I tried to manage it in my head. Notes. Timers. Guesswork. But when your nervous system is already overloaded, the last thing you need is another mental burden. So I built the tool I needed. Something that could help me see my limits instead of constantly running into them. I've used it every day. Refined it through real crashes, real data, real life.
And now I'm releasing it for others who are trying to live inside a body that no longer gives clear signals. This app exists so you don't have to do pacing alone.
— Kim, developer of Pacing Guard
Activity and rest, clearly structured
The app alternates between GO and REST phases with a visual countdown ring. Voice cues and haptic feedback tell you when to switch — no need to watch the screen. Adjust each phase to the duration that works for you.
Monitor your heart rate in real time
Connect a Bluetooth heart rate strap to see your current heart rate and session maximum. Set a personal heart rate limit and get alerted before you push too far.
Track your heart rate overnight
Monitor your heart rate through the night without alerts, cues, or screen wake — just quiet, continuous monitoring. Review your maximum heart rate the next morning.
Set it up your way
Choose voice cues, haptic feedback, spoken countdown, or silence. Adjust GO and REST durations independently. The app adapts to what feels comfortable — not the other way around.
A simple log of your sessions
Every completed session is saved with interval counts, duration, and heart rate data. No graphs, no gamification — just a clear record of what you did.
Easy on the eyes
Dark mode follows your system setting automatically. Ideal for low-light environments, evening sessions, or simply reducing visual strain.
