# NoiSee vs RTA Pro

The clearest difference is in-app purchases: RTA Pro at none against NoiSee's 4. RTA Pro also leads on update cadence (every 3 months vs every 9 months) and chart position (#188 vs unranked). NoiSee's advantage is ratings volume (242 vs 2) and price ($0.99 vs $5.99). On rating, ads, device support and iOS requirement there is nothing between them.

NoiSee costs $0.99 and RTA Pro $5.99 up front. NoiSee sells 4 one-off in-app purchases. RTA Pro asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.5 for NoiSee against 4.5 for RTA Pro. That said, the two scores are not equally well evidenced: NoiSee has 242 ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 63% of NoiSee's written reviews are positive against 50% of RTA Pro's.

NoiSee ships an update every 9 months, RTA Pro every 3 months. The most recent releases landed on September 24, 2026 and September 13, 2026 respectively.
