I’ve been building a running app called PaceGuru. The idea is simple:
Many running apps give you distance, pace, and heart rate — but very few help you understand what those numbers mean for your progress.
PaceGuru focuses on two things:
1. *Meaningful visualization* - A 6-axis radar chart shows how your recent training distributes across six pace zones (easy, aerobic, marathon pace, threshold, intervals, speed endurance). - You can set a target training ratio, and the chart fills automatically based on your workout history, making it easy to see whether your training structure matches your goals. - Widgets and Apple Watch complications bring progress and daily training metrics into your phone and watch face — a small “companion” to keep you moving forward.
2. *Personalized training* - Users can build their own schedule manually, and workouts sync automatically to the Apple Watch. - The app includes structured single-focus development blocks (aerobic, threshold, VO₂max, speed endurance, etc.). - There’s also a full Hansons Marathon Plan generator: enter your marathon goal and race date, and the app generates an 18-week schedule.
The app is available on iOS, and I wrote a more complete post here (screenshots, details, and design philosophy): https://www.paceguru.app/blog/en/2025-11-14-184-full-feature
I’d love feedback — especially: - Is the training visualization meaningful? - What would you add or simplify? - Do you think this approach improves clarity for self-coached runners?
Thanks!
