# SAS TMS vs TP

The clearest difference is review sentiment: SAS TMS at 67% against TP's 32%. SAS TMS also leads on iOS requirement (9.0 vs 14.0). TP's advantage is rating (2.3 vs 2.0) and update cadence (every 3 weeks vs every 2 months). 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.

TP holds the better App Store score, 2.3 against 2.0. That said, the two scores are not equally well evidenced: TP has 59 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 67% of SAS TMS's written reviews are positive against 32% of TP's, so the app with the better star average is not the one people write more warmly about.

SAS TMS ships an update every 2 months, TP every 3 weeks. The most recent releases landed on October 9, 2026 and October 17, 2026 respectively.
