The growth exchange for indie app developers. Show a member's promo card in your app → earn a credit for every verified click you deliver → spend credits to get your app promoted across the network. Free to join, forever.
Paste your store URL. We auto-build your promo card from your listing — icon, name, rating, one hook line. Nothing to design.
One script tag in your settings screen. Ten minutes, one release, ever. New promos rotate in automatically — you never ship an update because of us.
Every verified click you deliver earns a credit. Credits get your card into other members' apps. Real clicks, real installs, tracked end to end.
New to all this? Read the full walkthrough — every step explained so you can go from sign-up to your first swap in about 20 minutes.
An editorial-style recommendation — never a banner ad. Max once per session. Your users' trust is the asset; the network is built to protect it.
From sign-up to your first swap, in plain English. No jargon, no code skills needed beyond one copy-and-paste.
Click Join free, enter your email and a password, and confirm the email we send you. That's your account — no card details, no trial clock.
Paste your app's store link — Google Play, the App Store, or your web app's address. We fetch the icon, name and rating automatically.
Then pick a category (this controls who you can swap with — you're never shown to a direct competitor) and write your hook line: the one sentence users will see on your card. Say what the app does for them — e.g. "Every horse, sorted — care, travel & yard life in one app".
We give you a small token like swapmyapp-verify:ab12cd34. Paste it anywhere in your store listing description (the bottom is fine) or on your website, then press Check verification in your dashboard.
This keeps the network honest — nobody can promote an app they don't own. Verifying also grants your welcome credits: 25 if you're a founding member (the first 50 to join), 10 after that.
Copy your personal snippet from My Apps — it looks like this:
Paste it into a screen where a recommendation feels natural — most members use their Settings or About screen. Native app? Any web-based screen (a WebView) works. It matches dark or light themes, shows at most once per session, and if anything ever breaks on our side it silently shows nothing — it can never break your app. New promos rotate in automatically, so this is one release, ever.
Open Matches — you'll only see apps in complementary categories. Press Request swap on ones you'd genuinely recommend. When that developer requests you back, the swap activates itself: your card goes live in their app, theirs in yours.
Every real person who taps the card you host earns you +1 credit — counted once per device per day, verified on our servers. Your credits pay for your own card's clicks in other members' apps. Watch it all happen live in The Exchange, your dashboard feed.
Launching something big? A one-off £49 Launch Boost puts your card across the whole network for a week, and hosts earn 2× credits for carrying it — so everyone wants your launch to succeed.
Yes — joining and the core exchange (hosting, credits, swaps) are free for everyone. The first 50 members are founding members: they keep it free forever, get a bigger 25-credit welcome grant, shape the matching rules, and get first access to Pro. Paid extras (Launch Boost now, Pro later) are how the free exchange stays free.
No banners, no popups, no tracking SDK. One editorial-style recommendation card, in a screen you chose, at most once per session. Your users' trust is the whole point.
If you can edit your store listing and paste one line of code, you're qualified. There is nothing else to build, and you never ship another update because of us.
Every click goes through a signed link, only counts once per device per day, and only if we actually served that card to that device. Each app can earn from at most 10 clicks a day and balances cap at 200 credits — so nobody can hoard credits and crowd others out. And anyone caught clicking their own hosted cards is expelled for life, apps permanently blacklisted. No refunds, no appeal.
Remove the snippet and your swaps wind down — no lock-in, no penalty. Your account and credits stay put if you come back.
An indie dev with three apps in the network, playing by the same public rules as everyone else — read "Why this exists" below, or email pmdonkeylabs@gmail.com and a human answers.
"I built three apps — BoatMatey, PetHub+ and HorseHub+ — and hit the same wall every indie dev hits: the apps were good, but I couldn't afford the marketing to get them seen. Ads wanted £3 an install. Reddit bans self-promo. Store discovery is dead without traction.
So I built the thing I needed: a network where we promote each other instead of paying ad networks. My three apps are members #1, #2 and #3 — with a public credit ledger, playing by the same rules as everyone else."
— Martin, founder
The core exchange is free forever. Founding members also shape the matching rules and get first access to install attribution.
