# Notilify vs CaIculator

The clearest difference is in-app purchases: Notilify at none against CaIculator's 1. Notilify also leads on ads (none vs shown). CaIculator's advantage is ratings volume (27 vs 2) and iOS requirement (12.0 vs 16.2). On price, rating, update cadence and device support there is nothing between them.

Both are free to download. CaIculator sells 1 one-off in-app purchase. Notilify asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Notilify against 4.9 for CaIculator. That said, the two scores are not equally well evidenced: CaIculator has 27 ratings behind it against 2, so its average is the more settled of the two.
