How to promote your app on Reddit without getting banned

Short answer: to promote your app on Reddit, do not post ads. Find threads where people already describe the problem your app solves, answer the question fully, mention that you built a tool for it, and follow every community’s rules. Helpful replies in the right threads bring users. Link drops get removed and accounts get banned.

This guide is for solo founders with a working app. It follows Reddit’s site-wide rules, which forbid spam and content manipulation. Each subreddit adds its own rules on top. When a community says no promotion, respect it.

1. Search for the problem, not your product category

Your users do not search Reddit for “expense app.” They write “how do you all keep receipts organized for your accountant?” Search Reddit, and Google with “reddit” added, for phrases like these:

• “how do I [task your app does]”
• “is there a tool that [outcome]”
• “alternative to [the tool your buyers complain about]”
• “[problem] is driving me crazy”
• “what do you use for [task]”

Save every thread where the person asking matches your buyer. Note which communities keep appearing. Those are your communities, and they are rarely the startup ones.

2. Read the rules and earn a history

Open the sidebar and rules of each community. Some ban self-promotion, some allow it on specific days or threads, some require a disclosure. Spend a week answering questions there without mentioning your app. Moderators check account history, and an account that only posts links looks like spam because it is.

3. Write a reply that helps even without the link

The test: would this reply be upvoted if you deleted the last line? Use this structure:

1. Answer the question directly in the first line.
2. Give the steps or the trade-offs you learned (2–4 short lines).
3. Disclose and offer: "Disclosure: I built [app] because I had the same
   problem. It does [the one relevant task]. Happy to share it if useful."
4. Stop. Do not add a second pitch or a list of features.

Many communities prefer that you mention the tool and share the link only when someone asks. Follow the local norm.

4. When to post your own thread

Post your own thread only where it is explicitly allowed, for example a community’s feedback or “show your project” thread. Make it about the problem and what you learned building the solution, include a real screenshot or short demo, and ask a specific question. “Roast my landing page” threads give useful feedback; they rarely give users.

5. Track what converts

Use a tagged link (for example ?utm_source=reddit&utm_campaign=receipts_thread) where links are allowed, and record each reply in a sheet: thread, community, date, visits, signups, activated users. After two weeks you will know which communities and which kinds of question bring users.

In this example the niche community wins: fewer upvotes, but the people replying are actual buyers.

Mistakes that get apps banned

• Posting the same link in many communities on the same day.
• Using new or multiple accounts, or asking friends to upvote.
• Pretending to be a happy customer of your own app.
• Replying to old threads with only a link.
• Arguing with moderators instead of reading the rules.

Where AI and Crany fit

Finding the right threads every day is the slow part. AI can search for posts where people describe your problem, rank them by fit and draft a reply in your voice for you to approve.
