TapRev: SaaS Revenue Tracker

About

TapRev is an iPhone app that sends a notification for each sale, renewal, refund or chargeback from connected payment platforms, including Stripe, Paddle, Lemon Squeezy, Gumroad and RevenueCat. It combines them into a single MRR or revenue figure, with churn, subscription status and widgets. Users connect their own read-only API keys, which the listing says stay in the iOS Keychain on the phone with no account or server.
