Chartsy vs RedChurn

Chartsy is a web analytics product for SaaS founders that combines Stripe and Paddle billing records with website traffic. It calculates MRR, ARR, churn, LTV and cohort retention from invoice data, and includes expansion analysis and unit-economics measures. A tracking script attributes visits and signups to Stripe or Paddle revenue by marketing channel. ChartsyAI converts plain-English questions into charts without SQL; its chatbot handles follow-up questions and explains changes in revenue metrics. Supported sources are Stripe, Paddle Billing, Paddle Classic and BigCommerce. GDPR Mode avoids storing customer names and email addresses while metrics continue to work. Connections to Stripe and Paddle are read-only except for webhook registration. Weekly emails cover subscribers, MRR, churn, plan performance and geographic distribution. Four dashboard templates appear after initial synchronization. MCP supplies read-only data to ChatGPT and Claude.

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.
