# Theory Test Pro vs Herts Mobile

The clearest difference is rating: Theory Test Pro at 5.0 against Herts Mobile's 2.5. Theory Test Pro also leads on update cadence (monthly vs every 5 months). Herts Mobile's advantage is in-app purchases (none vs 1) and review sentiment (80% vs 67%). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. Theory Test Pro sells 1 one-off in-app purchase. Herts Mobile asks for nothing beyond the download.

Theory Test Pro holds the better App Store score, 5.0 against 2.5. Both are backed by a comparable volume of ratings — 2 and 2 respectively. Written reviews complicate that: 67% of Theory Test Pro's written reviews are positive against 80% of Herts Mobile's, so the app with the better star average is not the one people write more warmly about.

Theory Test Pro ships an update monthly, Herts Mobile every 5 months. Both last shipped on October 24, 2026.
