Both are free to download. Calcandy sells 2 in-app purchases, starting at $2.99 per month. METH asks for nothing beyond the download.
METH holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Calcandy has 64 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of METH's written reviews are positive against 75% of Calcandy's, so the app with the better star average is not the one people write more warmly about.
METH ships an update every 4 days, Calcandy every 5 weeks. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
