RedChurn vs Submetrics

RedChurn is a subscription analytics and retention platform for mobile apps. It tracks MRR, churn, trials, and cohorts, and automates flows for billing recovery, cancellation saves, trial retention, and win-back. Billing issues detected through webhooks can trigger dunning emails or an in-app card-update prompt at the subscriber’s next app opening. Cancellation tools include native iOS and Android save screens and email follow-ups within 48 hours. Trial cancellation flows can send J-3 and J-1 reminder emails and offer an in-app save flow. For expired subscriptions, multi-step emails and in-app prompts can encourage a return, with reactivation tracked in Red Center. The dashboard provides live metrics and segments by country, store, and plan, plus retention-flow and save attribution. Integrations listed are RevenueCat, Superwall, and Polar; email and in-app flow support varies by integration. Starter is free, billed monthly, for up to 50 active subscribers and one app, with 30 days of retention history. Growth is listed as available from 500 subscribers.

Submetrics is subscription analytics for indie founders, development agencies, and indie hackers, including SaaS products under $50K MRR. It tracks MRR, ARR, churn, customer lifetime value, expansion, and related unit-economics measures from billing data. The dashboard updates revenue metrics in real time as subscriptions start, expand, contract, or churn. Slack or email alerts can report cancellations, with reasons taken from Stripe metadata. Lifetime value can be segmented by plan, cohort, or acquisition channel, while retention is displayed in cohort heatmaps. The Pro plan adds AI revenue projections for three, six, and 12 months with confidence intervals. Stripe and RevenueCat integrations are live; Paddle is in beta, and three other connections are coming soon. Plans start at $19 a month, with a 14-day trial and no credit card required. Supported platforms are web, iOS, Android, and API.
