Lemon Squeezy revenue next to your app
Connect Lemon Squeezy and WhyItChanged pulls orders, subscription renewals and refunds in USD and adds them to your App Store revenue. Lemon Squeezy's API doesn't return the fee per order, so net revenue uses its standard 5% + 50¢ fee and is labelled estimated.
