Your Amazon Seller Central sales, ad spend and account health as one number you can check in two seconds. CaruSeller signs in to your own Seller Central account and turns it into a phone dashboard: today's orders and sales, what advertising cost you, what is left after it, and a push the moment the next order lands. THE DASHBOARD - Today's orders and sales, in your account's own currency, no conversion guesswork - Today, yesterday, last 7 days, this month, last month, last 90 days, this year, last year, all time, plus any custom date range - Ad spend, ad-attributed orders and NET (sales minus ad spend) right under the headline - A card per marketplace with units and sales, and an ad card with spend, ACOS and NET beside it - Marketplaces with ad spend but no sale yet are listed too, so nothing burns unnoticed - Home Screen and Lock Screen widgets for today's orders and today's sales, and today's count on the app icon ANALYTICS Sales chart with daily and weekly units and sales. Thirteen months of monthly history. Growth against the comparable prior period. Marketplace comparison, side by side. Return rates per product, from Amazon’s own report. Net Sales: what is left after ad spend, month by month. Organic versus ad-driven revenue. Ad efficiency with ACOS, ROAS, CTR, CPC and conversion rate per marketplace. And Amazon's own Account Health Rating for every marketplace you sell in. ADVERTISING - Ad spend per marketplace and per product, from your own advertising account - Campaigns: enable, pause and change bids in bulk, without leaving the app - One tap from the dashboard's ad card to the products that spent the money ALERTS - New sale push the moment Amazon reports it, with its own sound - Ad spend alert when today's spend reaches the limit you set, at most twice a day - Account health alerts when a marketplace's rating drops or its status is no longer normal COMMUNITY - Opt-in leaderboard: see where your sales rank against other CaruSeller users, under an anonymous handle CARUSELLER PRO - $9.99 per month, 7-day free trial - Campaign actions: enable, pause and bulk bid changes - Advertising analytics: ad efficiency, and the organic versus ad-driven split - Net Sales, month by month - The full per-product ad spend list instead of the top three Everything else above is free. PRIVACY You sign in on Amazon's own page inside the app. CaruSeller never sees or stores your Amazon password. Your figures stay on your device, and the leaderboard sends nothing until you opt in. One toggle hides every product title and image, so you can share a screenshot without giving away what you sell. CaruSeller is an independent app for Amazon sellers.

Verdict
The clearest difference is ads: CaruSeller at none against GMX's shown. CaruSeller also leads on iOS requirement (16.4 vs 18.0). On price, in-app purchases and device support there is nothing between them.
