# Propeller Calc vs MediaMaster® Remote

The clearest difference is rating: MediaMaster® Remote at 4.1 against Propeller Calc's 3.0. MediaMaster® Remote also leads on update cadence (every 4 months vs every 21 months) and ratings volume (11 vs 1). Propeller Calc's advantage is review sentiment (100% vs 60%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

MediaMaster® Remote holds the better App Store score, 4.1 against 3.0. That said, the two scores are not equally well evidenced: MediaMaster® Remote has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Propeller Calc's written reviews are positive against 60% of MediaMaster® Remote's, so the app with the better star average is not the one people write more warmly about.

Propeller Calc ships an update every 21 months, MediaMaster® Remote every 4 months. The most recent releases landed on September 26, 2026 and October 27, 2026 respectively.
