Sumly
Revenue and visitor analytics in one place for makers with apps and sites
Sumly brings your revenue and your traffic together. It reads payments from 22 providers, including Stripe, Paddle, Lemon Squeezy, Polar, Creem, RevenueCat, PayPal, Shopify, Gumroad, the App Store and Google Play, and adds them up after fees and refunds in euros. Next to that, it counts visitors on your sites and apps, so you can see which sources actually bring paying customers.
The site script ties each sale to the visit that brought the buyer, on your site and in your app. Store buttons carry the visit to Google Play and the App Store, so app payments through RevenueCat land in revenue by source, with a web to app funnel beside it. Mentions on Reddit, Hacker News, Bluesky, YouTube or blogs, and Google Search Console clicks, are marked on the revenue chart so you can see why the line moved.
Sumly also tracks costs and ROI by source, campaign and creator, packs a monthly zip and summary PDF for your accountant by project and country, and answers questions in plain words on the site or from ChatGPT and Claude over MCP. There are iPhone and Android apps with a notice for every sale, live visitor maps and Home Screen widgets.
Setup takes three steps: connect a read-only key, add one line to your site, and see which visits pay. Keys are encrypted at rest, no IP addresses are kept, and there is a 14-day free trial on every paid plan with no card required.
