Set Spotter turns your iPhone into an augmented-reality set finder for the card game Set®. Point the camera at a grid of cards and Set Spotter will highlight all the sets it sees. If you want to use it during a real game to determine if more cards should be dealt then you can turn off the highlight feature in the settings page and only the set count will be shown in the bottom left.

Verdict
The clearest difference is ads: Set Spotter at none against Pre's shown. Set Spotter also leads on update cadence (fortnightly vs every 7 months). Pre's advantage is iOS requirement (14.0 vs 16). On price, in-app purchases and device support there is nothing between them.
