Tried three focus apps this week. All of them nag and none of them just… work. Suggestions?

Draft reply ready: helpful, mentions your app naturally.

Quick answer

The most effective way to promote your app for free is to join the conversations where people are already asking for it. Growth Engine is an app promotion tool that continuously searches Reddit and X for posts where real people want an app like yours, ranks each thread by how ready the person is to try something, tells you why it matched, and drafts a helpful, non-spammy reply — turning "I don't know where to promote my app" into a daily list of warm conversations to join.

How it works

From published to promoted in three steps

Describe your app

Paste your App Store or Play Store URL, or just your keywords. Growth Engine learns what your app does and who it's for — no manual keyword lists to maintain.

Get a daily feed of warm threads

Every day we surface fresh Reddit and X posts where people are asking for exactly what you built, each scored by buying intent and tagged with why it matched.

Reply and grow

Open the thread, use the AI-drafted reply as a starting point, and join the conversation as a real person. Save the best threads and track what you've already answered.

The basics

Publishing isn't launching

You hit Publish and the installs didn't come. That's normal — the app stores don't send traffic to apps nobody is searching for yet. The fastest, cheapest users come from the places where people are already describing the problem your app solves, in their own words, today.

The catch is those conversations are scattered across thousands of subreddits and a firehose of posts on X, and they scroll away in hours. Finding them by hand is a second job. Growth Engine does that search continuously and brings the handful that actually matter to you.

Because every match comes with the reason it surfaced and a draft reply, you spend your time being helpful in the right rooms instead of hunting for them. That's how indie apps get their first hundred real users without an ad budget.

What Growth Engine does for you

A single workspace that turns the whole internet's app-shaped conversations into a short, prioritized to-do list.

Intent-ranked results

Not every mention is worth your time. Each thread is scored so the person actively looking for a solution rises above the person just venting.

Reddit + X coverage

One scan spans relevant subreddits and X conversations, so you're not maintaining separate searches on separate platforms.

Why it matched

Every result explains the signal it caught — a feature request, a competitor complaint, a 'does anything do X?' question — so you reply with context.

AI-drafted replies

Start from a helpful, human-sounding draft that mentions your app naturally. Edit and post — no cringe, no copy-paste spam.

Daily fresh scans

New threads surface every day and stale ones drop off, so your feed is always the freshest opportunities, not last month's.

Save & track

Bookmark the best threads, mark what you've replied to, and keep a running record of where your app is being discussed.

Frequently asked

Growth Engine, answered

Where does Growth Engine find these conversations?

It searches Reddit and X for public posts that match what your app does — feature requests, complaints about competitors, and 'is there an app that…' questions. You get a daily feed of the freshest, highest-intent threads.

Is this spam? Will I get banned from subreddits?

No. Growth Engine points you to relevant conversations and drafts a genuinely helpful reply that mentions your app only where it fits. You post as yourself, edit the draft, and add real value — the opposite of blasting links.

Do I need to build keyword lists?

No. Paste your store URL or a short description and Growth Engine figures out the topics and phrasing people use. It keeps scanning without you maintaining anything.
