Iaptic vs RevenueCat, Adapty & Qonversion
Iaptic is the only commercial in-app purchase infrastructure vendor with first-party Godot support*, and also covers Cordova/Capacitor, React Native, StoreKit 2 and the web. That platform breadth is the durable differentiator — competitors can change pricing overnight, but they can't ship a Godot SDK by tomorrow.
On cost, the category leaders charge a percentage of your revenue; iaptic charges a flat fee per transaction. This page compares the four head-to-head — platforms, pricing, features, and a worked cost example — so you can pick on numbers, not marketing.

Platform coverage — the durable difference
Iaptic ships first-party SDKs for Godot, Cordova/Capacitor, React Native, Swift/StoreKit 2, and JavaScript/web — all from the iaptic/j3k0/fovea ecosystem. RevenueCat, Adapty and Qonversion cover the mainstream mobile + web platforms but none ship a Godot SDK, and all three invest more heavily in Flutter and Unity (where iaptic focuses elsewhere). If your app runs on Godot, iaptic is the only commercial IAP-infrastructure option in this set.

What that breadth costs — and saves at scale
Platform coverage is the reason to pick iaptic; the pricing model is why it scales better. Revenue-share vendors bill a percentage of your monthly tracked revenue (MTR), so cost rises automatically as you grow. Iaptic bills per transaction, so cost stays predictable and is independent of how much each transaction is worth.
Assumption for this example: an average net revenue of $10 per transaction per month (a typical subscription price), so monthly transactions = MTR ÷ $10. Iaptic's cost is driven by that transaction count; the competitors' cost is driven by MTR directly. Qonversion charges a single flat 0.8% of revenue (its former 0.6% Starter tier was discontinued in Sep 2026).
| Monthly Tracked Revenue | Transactions / mo (assumed) | Iaptic | RevenueCat | Adapty | Qonversion |
|---|---|---|---|---|---|
| $5K MTR | 500 | $29/mo | $50/mo | $0/mo | $0/mo |
| $50K MTR | 5,000 | $299/mo | $500/mo | $500/mo | $400/mo |
| $500K MTR | 50,000 | $499/mo | $5,000/mo | $5,000/mo | $4,000/mo |
How iaptic is computed: FREE (≤100 tx), START $29 (≤500 tx), PRO $59 (≤1,000 tx), BUSINESS $299 (≤10,000 tx); above 10,000 tx add $0.005 per extra transaction. At $500K MTR (50,000 tx) that is $299 + 40,000 × $0.005 = $499/mo. RevenueCat = 1% of MTR (free until $2.5K). Adapty = 1% of revenue (free until $5K). Qonversion = flat 0.8% of MTR (free until $7K). Green marks the cheapest option in each row.

Different focus areas
These are all strong products. The difference is where each team invests. Pick the one whose focus matches your app.
Where iaptic's focus wins
- Cross-platform breadth. Only commercial vendor with Godot; strong Cordova/Capacitor (the plugin is j3k0-authored, 10+ years) and StoreKit 2. Competitors focus on the mainstream mobile platforms.
- Cost predictability at scale. At $50K MTR iaptic is $299/mo vs ~$500 for RevenueCat and Adapty; at $500K MTR iaptic is $499/mo vs $5,000 (RevenueCat/Adapty) and $4,000 (Qonversion).
- No revenue tax. High-ARPU apps (expensive subscriptions, one-off purchases) keep the same flat fee regardless of price.
- Longevity. In market since 2016 — a real trust signal after Glassfy shut down end of 2024.
Where the competitors' focus wins
- Below $5–7K MTR. Adapty is free to $5K MTR and Qonversion to $7K MTR with full features; iaptic's free tier is 100 transactions. For a low-revenue app, the competitors' free tiers are cheaper.
- Paywall & onboarding creation. RevenueCat, Adapty and Qonversion invest in no-code paywall builders and A/B testing; iaptic focuses on validation depth and cross-platform breadth. If a paywall builder is core to your workflow, pair iaptic's validation layer with the growth tool of your choice.
- Growth analytics. Predictive LTV, cohort analysis and Apple Search Ads attribution are deeper on the revenue-share platforms — that is where they invest.
- Refund defense. Adapty Refund Saver and Qonversion Refund Keeper share usage data with Apple to cut refunds — a focus area iaptic does not pursue.
- Flutter & Unity. RevenueCat, Adapty and Qonversion ship first-party Flutter and Unity SDKs; iaptic focuses its SDK effort on Godot, Cordova/Capacitor, RN, Swift and JS/web.
Pick the platform breadth and pricing model that fit your app
If your app runs on Godot or Cordova/Capacitor, or earns more than a few thousand dollars a month, the flat per-transaction model almost always wins. If you need a paywall builder, pair iaptic's validation layer with the growth tool of your choice.
