Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
034SPI holds the better App Store score, 4.2 against 3.0. That said, the two scores are not equally well evidenced: 034SPI has 42 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 76% of Ultimate9 TC's written reviews are positive against 55% of 034SPI's, so the app with the better star average is not the one people write more warmly about.
Ultimate9 TC ships an update every 6 weeks, 034SPI every 2 weeks. The most recent releases landed on October 8, 2026 and October 16, 2026 respectively.
