We hit a wall waiting on app store reviews anytime we wanted to try a new price, free trial, or intro offer. Moving onboarding and the paywall to the web let us push changes the same day, and run small price windows for specific geos or channels.
A few things bit us at first: currency rounding by country, caching that served old prices, and making sure the app picked up entitlements fast after a web purchase. Also learned to lock test cohorts so people don’t bounce between prices.
If you’re doing same-day price tests from the web, what broke for you the first time, and how did you keep the web purchase and in‑app entitlement in sync within minutes?
I moved all pricing logic to a web paywall with server rules.
Two fixes saved me time: cache bust with versioned query params, and force currency display from backend, not the client.
For sync, I post purchase to our webhook, then the app calls entitlement refresh. Web2Wave’s JSON + SDK setup helped because I could push price variants without a build.
I test daily by editing the web paywall, not the app. Changes go live instantly.
Web2Wave lets me swap price cards and trial lengths on the web. I run small geo cohorts, watch payment rate and refund flags, then roll forward or revert within hours.
Cache is sneaky. Add a version to paywall URLs and assets.
Also set a rule for country pricing so you do not show USD to EU users.
Entitlement refresh on app launch helped reduce support tickets.
Lock cohorts or your data lies
Run price tests behind a stable routing layer. Keep a sticky experiment key in a cookie and in your user session so the same person sees the same offer. Version your paywall JSON and include a build tag in the URL to kill cache. For entitlements, push a purchase event to your server, update the subscriber record, and force the app to refresh on next foreground. Also set guardrails: minimum sample size, geo isolation, and clear stop dates.
I set fixed test windows like 24 or 48 hours. It makes rollback simple.
Also log price shown, price paid, and exchange rate at checkout. Later you can explain odd refund spikes when currency drift happens.
Version your paywall and bust cache. That fixed delays.
