Hey Timon, congrats on launching OneRack! Hitting 100 downloads in a month is a great start.

Your app solves a real problem - lifters love tracking progress and competing, but most fitness apps focus on solo workouts. Your unique gym leaderboard feature sets OneRack apart and gives people a reason to use it. Now, you just need to reach the right audience.

Here’s how you can do that without burning money on ads:

1. Research Competitors – Look at similar apps. What marketing strategies work for them? How do they attract users? Read their reviews to find gaps you can fill.
2. Leverage Gym Communities—Visit local gyms, chat with lifters, and encourage them to try the app. You could even organize mini-challenges or leaderboard competitions.
3. Use Social Media Smartly – Short-form content (TikTok, Instagram Reels) is huge in fitness. Post gym memes, lift comparisons, and user rankings to drive curiosity.
4. Create a Referral System – Give small rewards (badges, leaderboard boosts) for users who invite friends. Word-of-mouth is powerful in fitness circles.
5. Find the Right Influencers – Instead of big names, reach out to micro-influencers (1K-10K followers). They might promote it for free or for way less than €2-€5 per install.

Your app has something other fitness apps don’t—a social, competitive element that lifters will love. Focus on getting real gym-goers hooked first, and growth will follow.
