Both are free to download. Calca app sells 4 in-app purchases, starting at $2.99 per year and AR Projector Tracing & Drawing sells 12 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Written reviews complicate that: 48% of Calca app's written reviews are positive against 42% of AR Projector Tracing & Drawing's, so the app with the better star average is not the one people write more warmly about.
