Best subreddits to find customers for health and fitness apps
Fitness subreddits are progress-log culture: people post routines, plateaus, and transformations, and the apps they used are part of the story. That makes organic word-of-mouth achievable — but the big communities enforce some of the strictest anti-promotion rules on Reddit, because supplement spam got there first. Earn mentions; don't place them.
The largest training community — routine and tracking questions appear daily, but promotion rules are unforgiving.
Weight-loss members compare calorie and habit trackers as a core part of their journey posts.
Runners discuss training plans and obsess over tracking apps and watch ecosystems.
Home exercisers follow structured programs and adopt apps that deliver progressions.
A community underserved by mainstream fitness apps, vocal about what existing tools get wrong.
Food-logging and macro questions surface users actively choosing a tracking app.
Trainers buy client-management and programming software — the B2B side of fitness tech.
Data-obsessed users try every new tracking tool and write detailed public reviews.
General lifters ask for workout-logging recommendations with less rule friction than r/Fitness.
How to engage without getting banned
- Recruit beta users in r/QuantifiedSelf and r/personaltraining, where trying new tools is the culture.
- In the big fitness subs, participate only in "which app" comment threads — never post about your product.
- Health claims trigger both mods and skeptics; describe features and let users report outcomes.
- For trainer-facing tools, r/personaltraining converts far better than any consumer fitness subreddit.
Frequently asked questions
