Running apps turned running into a spreadsheet. ZenRuns is a running journal — log your run in 2 seconds, build your rhythm and find joy in running. Runners who show up regularly — even with imperfect sessions — build lasting fitness. Chasing perfect data slows you down. ZenRun tracks what matters: did you show up? HOW IT WORKS - Log a run in 2 seconds. Pick your distance, enter your time, done. Use your Apple Watch or not. Run however you want, log it when you're back. - Weekly rhythm rewards showing up. Run twice a week to keep your rhythm going. Not pace. Not distance. Just being there. - 100 milestones to celebrate your journey. Your first 5K, your 100th run, a year of consistency, and beyond. - Circles, not leaderboards. Share your journey with up to 10 close friends. Build accountability and have some joyful competition. - Scenic run photos. Capture the joy of outdoor runs. Tag photos to distance markers. Build a visual album of your running journey over time. WHAT ZENRUNS DOES NOT DO - No GPS tracking. You could run without your phone. - No live pace alerts buzzing your wrist. Find your joy in running. - No leaderboards against strangers. - No heart rate zones, cadence, VO2 max, or vertical oscillation. WHO IT'S FOR - You run 2–5 times a week and want to keep doing that for years. - You value the running mindfulness as much as the physical fitness. - You've used tracking apps but yet you have not figured out how to stay consistent. - You care about running - You believe the best run is the one you actually did. BUILT BY A RUNNER, NOT A FITNESS COMPANY I've started and stopped running more times than I can count. I hardly ran at all in 2025. Then, at the beginning of this year, I set a simple goal: run 1,000km. Just to see if the habit could finally stick. I built ZenRun during the same period — alongside the runs, through the weeks of motivation and the weeks I nearly quit again. Every feature exists because it was important for me. 200km in, both the habit and the app are still going. No subscriptions. No ads. Just a runner building the tool they wished existed. Inspired by Born to Run, Murakami's What I Talk About When I Talk About Running, and the growing movement of runners leaving their GPS watches at home.
