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…

I'm working on mTOR, a free, science-based workout tracker I built to automate progressive overload. It's a local-first PWA that works completely offline, syncs encrypted between your devices using passwordless passkeys, and allows for plan sharing via a simple link. The core idea is to…

Hello HN! I made a game for smart bike trainers focused on gamified progression, real-world locations, and steering using a smartphone. It differs from other apps by requiring you to complete routes in a specific order, without the ability to skip or make it easier. It's available for Windows and macOS. Last year, I got into road cycling. Because of this, I acquired a smart bike trainer (you attach it to your bike and apps can control its resistance via Bluetooth). I tried a couple of apps but quickly became bored. I feel they are mostly focused on either online racing or a serious…
