PrettyMerch

Install PrettyMerch on your phone, connect it to your Merch by Amazon account, and get a notification every time a shirt sells. The dashboard shows daily, weekly, and monthly sales, royalties per marketplace, and your best-selling designs — so you don't have to keep refreshing the Merch dashboard in a browser. The free version covers core tracking; PrettyMerch Pro adds advanced analytics, product breakdowns, and historical trends.
