# RTA vs SW array

The clearest difference is rating: SW array at 5.0 against RTA's 3.9. SW array also leads on review sentiment (100% vs 61%) and in-app purchases (none vs 2). RTA's advantage is update cadence (every 3 months vs every 88 months) and price ($4.99 vs $8.99). On ads, chart position, device support and iOS requirement there is nothing between them.

RTA costs $4.99 and SW array $8.99 up front. RTA sells 2 one-off in-app purchases. SW array asks for nothing beyond the download.

SW array holds the better App Store score, 5.0 against 3.9. That said, the two scores are not equally well evidenced: RTA has 26 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 61% of RTA's written reviews are positive against 100% of SW array's.

RTA ships an update every 3 months, SW array every 88 months. The most recent releases landed on September 24, 2026 and September 19, 2026 respectively.
