# AD DSP vs COBY Smart

The clearest difference is rating: COBY Smart at 3.7 against AD DSP's 2.3. COBY Smart also leads on iOS requirement (11.0 vs 15.6). AD DSP's advantage is review sentiment (100% vs 60%). On price, ratings volume, update cadence and ads there is nothing between them.

COBY Smart holds the better App Store score, 3.7 against 2.3. Both are backed by a comparable volume of ratings — 6 and 9 respectively. Written reviews complicate that: 100% of AD DSP's written reviews are positive against 60% of COBY Smart's, so the app with the better star average is not the one people write more warmly about.
