# Amazon Seller vs InternetMastery

The clearest difference is review sentiment: InternetMastery at 100% against Amazon Seller's 45%. InternetMastery also leads on rating (5.0 vs 4.6) and device support (3 vs 1). Amazon Seller's advantage is price (Free vs $9.99) and in-app purchases (none vs 1). On update cadence and ads there is nothing between them.

Amazon Seller is free to download; InternetMastery costs $9.99 up front. InternetMastery sells 1 in-app purchase, starting at $9.99 per month. Amazon Seller asks for nothing beyond the download.

InternetMastery holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Amazon Seller has 109K ratings behind it against 8, so its average is the more settled of the two. Written reviews point the same way: 45% of Amazon Seller's written reviews are positive against 100% of InternetMastery's.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 27, 2026 and October 16, 2026 respectively.
