# Developer Laboratory vs Ai Chat

The clearest difference is price: Ai Chat at Free against Developer Laboratory's $0.99. Ai Chat also leads on update cadence (daily vs monthly) and review sentiment (70% vs 60%). Developer Laboratory's advantage is rating (4.7 vs 3.7) and ads (none vs shown). On ratings volume, in-app purchases, device support and iOS requirement there is nothing between them.

Ai Chat is free to download; Developer Laboratory costs $0.99 up front. Developer Laboratory sells 8 one-off in-app purchases and Ai Chat sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Written reviews complicate that: 60% of Developer Laboratory's written reviews are positive against 70% of Ai Chat's, so the app with the better star average is not the one people write more warmly about.
