# Trinity Airways vs SRT

The clearest difference is monetization model: SRT at free against Trinity Airways's free with in-app purchases. SRT also leads on rating (1.3 vs 1.0) and ratings volume (76 vs 2). Trinity Airways's advantage is update cadence (fortnightly vs every 2 months). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

SRT holds the better App Store score, 1.3 against 1.0. That said, the two scores are not equally well evidenced: SRT has 76 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 13% of Trinity Airways's written reviews are positive against 25% of SRT's.

Trinity Airways ships an update fortnightly, SRT every 2 months. The most recent releases landed on October 13, 2026 and October 14, 2026 respectively.
