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. Founding members join free — and pay nothing, ever.
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, and each app can only ever be listed once, on one account. Verifying also grants your welcome credits: 25 if you're a founding member (the first 50 to join), 10 after that.
Joining after the founding 50? A one-off £2.99 sign-on fee (PayPal) is paid here, before your first app goes live — once, ever. It covers admin costs and keeps multi-account abuse out of the exchange.
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.
Google Play requires new personal developer accounts to recruit 12 testers for 14 consecutive days before publishing publicly. The Tester Exchange lets members test each other's apps and leave real structured feedback — clearing that wall the way Google intends, without paying a Fiverr farm.
Post a test request with your Play opt-in link and a short questionnaire of proof-of-use questions. Other members join, test your app, and submit feedback. The website scores the feedback automatically — only someone who genuinely used the app can answer the questions well. You test their apps in return.
Free for entitled members (founding members and anyone who has paid the £2.99 sign-on fee). Go to Tester Exchange in your dashboard to get started.
The exchange itself (hosting, credits, swaps) is free for everyone — credits can't be bought. The first 50 members are founding members: they pay nothing at all, ever, get a bigger 25-credit welcome grant, keep a 4× credit ceiling (200) for life, shape the matching rules, and get first access to Pro. Members who join after the founding 50 pay a one-off £2.99 sign-on fee before their first app goes live — it covers admin costs and keeps multi-account abuse out, and is never charged again. 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 have a ceiling (50 credits per app slot; founding members keep 200 for life) — so nobody can hoard credits and crowd others out. Each app can only ever be listed once, on one account, and members after the founding 50 pay a one-off £2.99 sign-on fee — so multi-account farming is pointless. 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.
A reciprocal beta-testing community built into SwapMyApp. New Google Play personal accounts must recruit 12 testers for 14 days before going public. The Tester Exchange lets you and other indie devs test each other's apps and leave real structured feedback — clearing that wall for free, without paying Fiverr farms. Free for members who have paid the one-off £2.99 sign-on fee, and for founding members.
Yes. Genuine reciprocal testing with real, structured feedback is exactly what Google's closed-testing programme is designed for. What is not allowed is fake or incentivised installs — farms where testers tap opt-in and disappear. The Tester Exchange requires answering app-specific proof-of-use questions that only a real user can answer; the feedback is scored automatically and has to be substantive. We expel anyone who games it.
"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.
