24 alternatives to AthleteData – AI coach for endurance athletes that messages you first
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…

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…

Hey HN, I'm a solo developer and I built Steps: Workout & Pedometer, an iOS pedometer and workout tracker. Last week, two German iOS publications wrote about the app. I didn't pitch them. I didn't send a press release. I didn't even know it was happening. I woke up to a spike in downloads, checked the analytics, and traced it back to their articles. That coverage pushed the app past $1,000 in sales. I still have no idea how they found the app. I'm wondering if anyone here has experience getting featured in publications, whether organically or through outreach. What worked for you? Any tips…

Proxima▲77Despite there being lots of information out there on how to train in the gym, I still get asked by beginners the same fundamental questions. I decided to build a tool that would allow them to create their own programs in a matter of seconds. I plan soon to create another tool that will rate the quality of these AI built workouts to help improve the programs over time.

I've just launched this little iOS app as an alternative to Apple Fitness, which is cluttered and chaotic when it comes to visualizing basic workout stats and metrics. The idea is to focus on a clean, minimalistic design and only show high-level metrics that are actually useful, e.g. how often did I work out this week/month/year, cardio vs strength vs mobility, surf session count in February, etc. It's free and offline. Also, no signup, no ads, no data sharing, no social feeds, and no notifications. Just open it and get a quick glance at the state of your workout game within 2s.…

I've been building this for a few years under the name "Statistics for Strava" but I renamed it to Dreeve recently because of Strava's recently changed API usage terms. They paywalled their API. You point it at your activity files (FIT/TCX/GPX) or connect a Strava account, and it gives you a dashboard with segment efforts, gear and maintenance tracking, a heatmap, monthly calendar view, milestones and a year-in-review. It runs as a Docker container, stores everything in SQLite, and nothing leaves your machine. Stack is PHP 8.5 + Symfony, SQLite, Docker Compose. Simple,…

i built a heart rate zone training app for runners. ios + apple watch. custom zones, real-time haptics, post-run graphs. all the “smart” stuff you’d expect. but i never talked to a single runner before building it. not even myself lol. started as a thesis → kept building → added features → added a paywall (€4/month!) → launched it → and yeah… no one cared. zero feedback. zero users. just code in the void. i recently made the whole thing free. not trying to “sell” anything now — just seeing if it’s actually useful, and listening this time. curious how others handle this. ever build…

Hi HN, I'm an indie dev who built this to settle a long-running argument with my teenage son about who lifts more at the gym. I wanted a workout tracker to kept our data side-by-side on a leaderboard, and let us swap training plans without texting screenshots back and forth. Nothing I tried did all three without a subscription wall, so I wrote my own. Most of the app is free, it covers the full workout experience and progress tracking with 80+ exercises. The one-time purchase unlocks multiple plans, custom movements, and the social/sharing features, mainly to pay for the infra. The…

Strava's awesome for viewing individual training runs, but it doesn't offer a consolidated view for elite runners' training. So I scraped >150k activities from 450+ elites with public accounts for their 2024 training log. GH Repo: https://github.com/danielcwq/elite-endurance-viz/ Would love any feedback + feature requests!

pairform▲6LLMs got very good at coaching, especially for extremely well studied sports like running. I built Pairform to provide some structure and context for the models to use for MUCH butter consistency and accuracy in coaching help. It was surprisingly difficult to get consistent accurate analysis for things related to dates, total distances, etc. But, think it's in a pretty good place now! Free to use so please check it out and offer some feedback. Hook up Strava, Whoop, and Withings for automated syncing/context for your AI coach. The built in chat has some limits (it's on my Claude…
