Why CashSDK fits music

One SDK for the whole streaming money stack.

Plan-picker paywalls, experiments, free trials, and validated receipts, the pieces a music app needs to price Premium by household, without building billing infrastructure.

Plan-picker paywalls you A/B over the air

Design the Individual/Duo/Family/Student picker in the dashboard, publish it without an app release, and change plans, price, and trial length for any cohort instantly.

Experiment on price & trial

Run holdouts on the Premium upgrade, test a 7- vs 30-day trial and student price, and measure conversion and revenue per install, not vibes.

Explore

Subscriptions, trials & credits

Recurring plans with intro trials, plus consumable credits for audiobooks or coins for gifting, granted and burned server-side so a purchase can’t be replayed.

Explore

Validated receipts

Every Apple and Google receipt is verified server-side into a clean entitlement, with no receipt server to run.

Explore

Localized pricing, both stores

One catalog prices every plan in local currency across the App Store and Google Play, with free trials and intro offers honored natively.

Built for the whole stack

Price Premium by household from one integration.
