Keep your gear honest
Geer watches the wear on every part of your bike using your Strava rides, then tells you when a chain or a set of pads is due. trackmy.shoes does the same thing for runners, tracking mileage across your shoe rotation so you know when a pair is cooked.
Make something out of your data
Kudos Post takes one of your activities, drops the route and stats onto a photo, then prints it as a real postcard and mails it. Probe turns your cycling data into clean summary cards and year-end recaps. Sports Metrics, an iOS app, builds editorial-style annual recaps and career stats across a handful of sports. And Kraina slowly uncovers a “fog of war” map of everywhere you have run, ridden, or hiked.
Train with a coach (or a robot one)
Three AI coaching apps landed this month. PersonalBestPace is built for cyclists who train with power, pulling in Strava, Garmin, and Wahoo data and adjusting your plan week to week. Pelaris reads your Strava activity summaries and builds an adaptive plan for multi-sport athletes, and it is free. Flow State Endurance is a training calendar that imports your Strava and Garmin history and reshapes your week around a race goal. If you swim, MySwimPro is one of the bigger names in the pool, with structured workouts and plans that sync to your watch.
A couple of odd ones (the good kind)
Weasel Wes Cycling Simulator is a 2D indoor cycling sim for Windows that talks to your trainer over ANT+ and Bluetooth and uploads to Strava. It costs $1.99 once, with no subscription. Health Sync is the quiet utility a lot of people need: it moves your activities and health data between Strava and platforms like Garmin, Huawei, and Fitbit, and lets you filter what actually syncs.
That is the month. If you built something that connects to Strava, or you use something that should be on here, send it over.
