If you’re building something new, Reddit can be one of the best free places to:
✅ Get beta testers
✅ Collect brutally honest feedback
✅ Find your first users or customers
✅ Validate ideas before you scale
But a word of caution → Reddit is not a billboard.
The key is to contribute first, promote second. Many subs have weekly threads (e.g. “What are you working on?”) where you can share openly without breaking rules.

⚡ Tips for Using Reddit Effectively:
- Start with value → Post insights, answer questions, or share your journey before linking your app.
- Use niche subs → Beyond these 50+, think about where your ideal users hang out (fitness, crypto, education, photography, gaming, etc.).
- Follow subreddit rules → Every sub has its own stance on promotion — break them and you’ll get banned.
- Test different angles → Sometimes framing your post as “I built X to solve Y problem” works better than “Check out my app.”
👉 The best conversions often come from smaller, niche subreddits where your target customers are already discussing the exact problem your app solves.
