# ServiceTitan Mobile vs One Onsite

The clearest difference is rating: ServiceTitan Mobile at 2.9 against One Onsite's 2.6. ServiceTitan Mobile also leads on ratings volume (1.7K vs 98). One Onsite's advantage is iOS requirement (15.0 vs 17.0). On price, review sentiment, update cadence and ads there is nothing between them.

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

ServiceTitan Mobile holds the better App Store score, 2.9 against 2.6. That said, the two scores are not equally well evidenced: ServiceTitan Mobile has 1.7K ratings behind it against 98, so its average is the more settled of the two. Written reviews complicate that: 19% of ServiceTitan Mobile's written reviews are positive against 23% of One Onsite's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 5 weeks. The most recent releases landed on October 26, 2026 and October 21, 2026 respectively.
