1K Users — Get Your First 1,000 Users by Helping Other Builders

1K Users is a free platform where indie makers, solo founders, and bootstrapped builders get their first 1,000 users through structured feedback exchange. Submit your app, review other builders' products, and climb the rankings. Your app's visibility is directly tied to how much you contribute — the more helpful reviews you write, the higher your app ranks in the feed.

How the Ranking System Works

Every app on 1K Users has a dynamic rank score that determines its position in the feed. Your rank increases when you write thoughtful reviews for other builders' apps (minimum 50 characters each). Reviews that builders mark as helpful boost your score even further. The algorithm also factors in your app's average star rating (1-5 stars) from received reviews and applies a 14-day recency window — so active participants stay at the top while inactive listings gradually move down. The formula rewards consistent, quality engagement over one-time participation.

How to Submit Your App

Click "Add App" and paste your app's URL with a short description. The system automatically visits your site, extracts your app name, icon, tagline, and relevant metadata (categories, platforms, region) using AI. You can review and edit everything before publishing. Your app appears in the feed immediately after submission.

How Reviews and Feedback Work

When you see an app in the feed, click "Try it" to visit the product, then come back and write a review. Reviews must be at least 50 characters to ensure substance. You can also leave a 1-5 star rating. Builders receive your feedback immediately and can respond. If a builder doesn't acknowledge your review within 72 hours, it's automatically marked as helpful and counts toward your rank score.

The Personalized Feed

During onboarding you select your interests (categories like Productivity, Developer Tools, AI/ML, E-commerce, Finance, Health, Education, and more), the platforms you build for (Web, iOS, Android, Mac, Windows, API, Chrome Extension), and your country. The feed's "For You" section surfaces apps that match your selections first, ordered by rank score. Below that, you'll find other apps sorted by relevance.

Who Should Use 1K Users

Any builder who has shipped or is about to ship a product and needs early users, honest feedback, or both. This includes indie hackers launching a SaaS, solo developers with a side project, bootstrapped startup founders looking for product-market fit signals, creators building mobile apps or browser extensions, developers offering APIs or developer tools, and makers in any category from fintech to health to design tooling. The community spans 19 regions including US, UK, Canada, Germany, France, Australia, India, Brazil, Japan, South Korea, Singapore, and more.

Why It Works Better Than Alternatives

Unlike Product Hunt or Show HN posts that give you one day of visibility, 1K Users provides ongoing, compounding exposure. Your app stays in the feed and keeps climbing as long as you stay active. The built-in incentive structure directly rewards contribution — your rank rises with every helpful review you write. And unlike paid user acquisition, it costs nothing. The only currency is your time and genuine engagement with other builders' products.
