Tool list, 2026
Churn recovery and win-back tools for subscription apps (2026): pricing model compared
Churn recovery tools for subscription apps charge in one of three ways: a flat monthly fee (Churnkey, Churn Buster, WinbackFlow), a share of what they recover (FlyCode, Churn Solution, Winback), or as part of a platform you already pay for (Stripe Billing, RevenueCat, Superwall). For app founders the bigger split is billing: of the ten tools below, only RevenueCat, Recurflux, Superwall and Winback state App Store or RevenueCat support on the pages we checked on 17 Oct 2026. No tool is best for everyone; the table shows who each one fits.

Pricing and features as each vendor describes them on its own site or listing, checked 17 Oct 2026. "Not stated" means the page we checked did not mention App Store or RevenueCat support; ask the vendor if you need it. Vendor numbers are vendor claims. Prices change, so check each site before you buy.
Why App Store apps are a different case
Most tools on this list were built for web billing. On Stripe, the cancel button is on your own site and failed cards are a large part of churn, so cancel flows and dunning carry most of the weight. Stripe itself says its users recover 55% of failed payments on average (Stripe Billing, vendor claim).
App Store subscriptions work differently. The cancel happens in Apple's settings, where a web cancel flow never sees it. And billing failures are a smaller share: RevenueCat found 14% of App Store cancellations are involuntary billing failures, against 31% on Google Play (RevenueCat State of Subscription Apps 2026). Most App Store churn is a choice, so what matters is reaching people after they leave. Some do come back: 20% of monthly subscribers and 5% of annual subscribers reactivate within a year (RevenueCat SOSA 2026 part 2).
Is there churn software that only charges when it recovers revenue?
Yes, several, but "pay on success" means different things in each:
| Tool | What you pay | When you start paying | Source, checked on |
|---|---|---|---|
| FlyCode | A fee based only on recovered revenue above a baseline | When recovery beats the baseline | flycode.com, 17 Oct 2026 |
| Churn Solution | "Pay As We Save" share, or 0.03% to 0.1% of MRR | Depends on the option you pick | GetApp listing, 17 Oct 2026 |
| WinbackFlow | Flat $99, $299 or $699 a month by MRR | After its first recovery, per its own wording | winbackflow.co, 17 Oct 2026 |
| Winback | 15% of revenue from subscribers who come back | Only when someone returns, for 6 months per returner | Winback pricing, 17 Oct 2026 |
FlyCode's own comparison article also describes Butter Payments as pay on recovery. We did not check that on Butter's site.
How to choose
You bill on the web through Stripe
- Turn on Stripe's own recovery first. You already pay for it.
- If most cancels happen on your own cancel page, a cancel flow tool such as Churnkey or Churn Buster can act before people leave. Winback does not do cancel flows.
- If you would rather pay on results: FlyCode suits larger brands, Churn Solution covers Stripe consumer subscriptions from $5K to $5M MRR, and WinbackFlow starts its flat fee after a first recovery.
Your app sells through the App Store and RevenueCat
- Set up Apple's own tools first: win-back offers for lapsed subscribers and Retention Messaging at the moment of cancel.
- If you sell on RevenueCat Web and one English email is enough, RevenueCat's web win-back beta is the cheapest option. See RevenueCat win-back for what it covers.
- Recurflux and Winback both work with RevenueCat. Recurflux sends dunning and win-back emails; Winback writes one personal message per lapsed subscriber and charges only when someone returns. Both are new. Compare them side by side.
- Superwall fits if you want paywall testing and Retention Messaging in one place.
Small business or large
A flat fee is predictable, but it costs the same in a slow month. A share of revenue costs nothing when nobody returns, and more when many do.
Illustration, not a benchmark: on a $9.99 monthly plan, 15% is about $1.50 a month per returning subscriber, for 6 months. Churnkey's Starter plan is $250 a month billed yearly. At that price, a percentage fee costs less until roughly 167 returners are paying at the same time. Run your own numbers before you decide.
Where Winback fits, honestly
Winback is new. We are onboarding the first apps by hand and have no customer results to show yet. We run it on our own App Store app, AGUNA, first. It has no cancel flows, which Churnkey and Churn Buster offer. It does have a public, read-only MCP server that AI agents can query for pricing, fit and a win-back estimate. What it does have: RevenueCat and Stripe support, a personal message per person within limits you set, a planner you can use free in your browser, and no fee unless someone comes back. See Winback vs Churnkey for a closer comparison.
Winback is not WinbackFlow, WinbackEngine or Winback Labs. Those are separate companies with similar names.
How we made this list
We read each vendor's own pricing and product pages on 17 Oct 2026 and wrote down what they say, not what we guess. Where a page did not mention App Store or RevenueCat support, we wrote "Not stated". Winback is our product, so we listed what it does not do as well. If something here is wrong or out of date, email support@winbackhq.com and we will fix it.
FAQ
Is there churn software that only charges when it recovers revenue?
Yes. FlyCode charges only on recovered revenue above a baseline. Churn Solution offers a Pay As We Save share. WinbackFlow says you pay nothing until its first recovery, then a flat fee. Winback charges 15% of revenue from subscribers who come back, for 6 months, and nothing else.
Which churn recovery tools work with RevenueCat and the App Store?
On the pages we checked on 17 Oct 2026: RevenueCat itself, Recurflux and Winback work with RevenueCat, and Superwall supports Apple Retention Messaging. Churnkey, Churn Buster, FlyCode, WinbackFlow and Churn Solution did not state App Store or RevenueCat support.
Does RevenueCat have win-back campaigns?
Yes, in beta. They email a Claim offer link when a subscription expires, and need RevenueCat Web with RevenueCat Billing, Stripe Billing or Paddle. The beta is English only, with no email customization and no audience targeting.
Why does this list not name a winner?
Because the right tool depends on where you bill and how big you are. A Stripe SaaS with a web cancel page needs different things from an App Store app. Winback is our product and is on this list, so we show the facts and let you choose.
Who is behind Winback?
AGUNA Wellness Ltd (RC 9590421) in Abuja, Nigeria. We run Winback on our own subscription app, AGUNA, first. Winback is new and has no customer results yet.
