# RTA Pro vs Impulso

The clearest difference is price: Impulso at Free against RTA Pro's $5.99. Impulso also leads on ratings volume (15 vs 2) and iOS requirement (12.0 vs 17.6). RTA Pro's advantage is rating (4.5 vs 1.7) and review sentiment (50% vs 12%). On update cadence, ads, in-app purchases and device support there is nothing between them.

Impulso is free to download; RTA Pro costs $5.99 up front. Neither carries in-app purchases, so what you see is what you pay.

RTA Pro holds the better App Store score, 4.5 against 1.7. That said, the two scores are not equally well evidenced: Impulso has 15 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of RTA Pro's written reviews are positive against 12% of Impulso's.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on September 13, 2026 and September 21, 2026 respectively.
