Appfuel is the first tool that combines keyword optimization and viral growth loops at indie pricing. The same growth playbook enterprise teams use — without the enterprise bill.
“I just want one tool that tells me which keywords to use AND helps me get more users through referrals — for $20–40/mo, not $200.”
— Every indie developer we talked to during market research
Enterprise ASO tools charge $200–999/mo and don't touch viral growth. Growth SDKs cost extra on top. Appfuel merges both for what you'd spend on lunch.
Start with ASO to get discovered. Add viral growth to multiply. Unlock the AI copilot when you're ready to scale.
Get discovered in the app stores. AI-powered keyword research, optimized metadata, and continuous rank tracking.
Turn every user into a growth channel. Smart referral programs, share triggers, and retention mechanics — drop-in SDK.
Your AI growth lead. Analyzes your metrics, recommends experiments, writes copy, and runs A/B tests autonomously.
The biggest apps in the world grew through ASO + viral loops. Appfuel brings the same mechanics to indie developers.
Grew from 100K to 4M users in 15 months using a referral program that rewarded both sides with extra storage. No paid acquisition needed for the initial rocket ship.
Viral referral loops80% of Duolingo's growth comes from organic channels — ASO, word of mouth, and viral mechanics like streaks and leaderboards. Almost zero paid acquisition for core growth.
ASO + organic growthIf you'd rather ship features than study keyword rankings, Appfuel handles the growth playbook.
You shipped an app but downloads are flat. You don't have $500/mo for ASO tools or time to learn growth marketing. Appfuel is your $29/mo growth department.
Zero growth headcount, all engineers. Appfuel acts as your AI growth lead — running keyword research, testing store listings, and building referral mechanics.
Your app works. Now you need users who pay. Appfuel bridges the gap between "launched" and "growing" with systematic ASO + viral loops.
Appfuel pairs with your existing monetization layer. Adapty, RevenueCat, or Superwall handle paywalls — we handle getting users to your app.
Those are enterprise ASO tools ($200–999/mo) built for large teams with dashboards you'll never use. Appfuel combines ASO + viral growth in one tool, at indie pricing ($29–69/mo), and the AI does the analysis for you.
Not to start. The ASO Engine ($29/mo) is pure SaaS — no code changes. When you're ready for viral growth loops and referrals, you add our lightweight SDK. It's a 5-minute integration.
Yes. Appfuel optimizes for both the Apple App Store and Google Play Store. Keyword research, rank tracking, and store listing optimization work across both platforms.
That's exactly who we built this for. Start with the ASO Engine to get discovered organically. Once you have steady downloads, add the viral growth SDK to multiply them. You don't need scale to start.
Yes. Monthly billing, no annual contracts, cancel in one click. We don't do the enterprise lock-in thing.
On the $69/mo plan, the AI analyzes your app metrics, suggests growth experiments, writes optimized store copy, and runs A/B tests autonomously. Think of it as a growth lead that works 24/7.
