Transition▲76Hey HN, I’m Alex, a triathlete, dad, and software engineer. I’ve been building Transition — an app for triathletes that creates adaptive training plans based on your goals, schedule, and workout data (Garmin, Strava, etc). Most plans are static, which never really worked for me as a parent and someone with an unpredictable schedule. Transition adjusts every week using your actual workouts and progress, so the plan changes when you miss a session, set a new PR, or need to shift your priorities. I built this because nothing else was flexible enough for my life, and I’m curious if others have…

Smart Runner▲94Ran my first marathon. Didn’t want to keep paying so much for Runna. So I built a running coach app, and then kept improving it more and more, i think it’s pretty good now. Give it a try and share your thoughts.

Runo 2.0▲132I built Runo after years of inconsistent marathon training. GPS watches tell you your pace AFTER it's too late. So I made a simple metronome that plays a beat at your target cadence (steps per minute). New in 2.0: Apple Watch haptics (run to the beat without headphones), Strava sync, and social features. 4.7 on App Store, 10k+ runners. Would love feedback from the HN community.

Im a triathlete and the data for my training lives in 6 apps: Garmin, Strava, WHOOP, Intervals.icu, Wahoo, Withings, Apple Health, sometimes Hevy. Every morning Id eyeball a few of them and make a call on whether to do the planned session. For the past month I have been building a thing that does this for me, and got it to the point where I use it myself every day. It OAuths into whatever platforms you connect, reconciles the activities (tbh harder than it sounds — same ride shows up in Strava, Garmin, and Wahoo with different timestamps and rounding), computes daily load and readiness, and…
