Best Appifyfor Shopify appsBest Appifyfor Shopify appsFusionmetrics answers "why did my revenue change?". BestAppify answers "why did my App Store position change, and what are my competitors doing?". They overlap on one thing — Partner API revenue — and on that one thing, Fusionmetrics goes deeper.
Fusionmetrics is revenue analytics. It connects to your Shopify Partner account and, in its own words, lets you “See which Merchants and plan changes account for revenue gained or lost” (fusionmetrics.com). Its site lists Shopify Partners, Stripe, Google Analytics, BigQuery, Slack and MCP as connections — and no App Store data source.
BestAppify is App Store intelligence. We crawl the public Shopify App Store every day, so you see category positions, rival listings, reviews and listing changes for any app — yours and your competitors' — with nothing connected. Connect GA4 and you add the keyword positions merchants actually saw.
Where we overlap, they are ahead. Our Pro plan also reads the Partner API for MRR, churn and trials, month by month. Fusionmetrics breaks each revenue movement down to the merchant and plan change behind it, supports Stripe billing, and is free up to $5k tracked MRR. If revenue is the question, start there. If App Store search is the question, they don't try to answer it.
Every Fusionmetrics claim below comes from their public site, pricing page, API docs, changelog or reports, checked 27 October 2026. We have not used their product from the inside. They ship often, so if something here is out of date we'd rather hear about it and fix it — please tell us.

If the question you keep asking is "which merchants changed my MRR this month, and why?", Fusionmetrics is built for exactly that: per-merchant revenue movements, Stripe support, and free until your app passes $5k MRR. It does not track the App Store, so it won't tell you where you rank or what a competitor changed.
If the question is "why did installs move?" — where you sit in the App Store, who passed you, what they changed in their listing, and what merchants say in reviews — that is BestAppify, and it works on day one with nothing connected. Plenty of teams would reasonably run both: Fusionmetrics for the revenue ledger, BestAppify for the store.
No Partner token, no GA4, no traffic needed. Every app on the Shopify App Store — including your competitors' — already has data in BestAppify.
