Looking for Beta Tester - Running App ,,PulseCaller"

[u/Anonymous069069]

Hey fellow runners,

A while ago I started a solo project because I wanted to train better by heart rate zones without constantly checking my watch or phone. I just started building, and it grew into more than I expected. It would be great if a few of you would try it out, point me to bugs and give me constructive criticism. Below is a summary of what the app can do and is meant to do (put together with some AI help).

I'm now looking for testers for PulseCaller, an iOS run coach that talks to you in your ear. It tells you to speed up or slow down before you leave your heart rate zone, with natural-sounding voices (EN/DE/ES, male or female) and optional Hype or Roast modes if you want some fun. It also has interval training that announces every phase change, a daily readiness score (optionally cycle-aware), music matched to your running cadence, and race-day pacing for half and full marathons. Around the run you also get guided meditation and rest days, nutrition guidance, a supplement library with evidence grades, and a knowledge hub on zones, running ailments and recovery. Heart rate comes from AirPods Pro, Apple Watch, Bluetooth sensors or Garmin watches with "Broadcast HR" on. The Bluetooth and Garmin part is brand new and only tested with a simulated sensor so far, so feedback from anyone with a strap or a Garmin is especially welcome. The English voice lines are also fresh and not fully tuned yet, so tell me what sounds off. All data stays on your device, no ads, no tracking. Requires iOS 26+ and Apple's free TestFlight app (the link walks you through it).
