# Calculator vs Thingamabob

The clearest difference is in-app purchases: Thingamabob at none against Calculator's 1. Thingamabob also leads on ads (none vs shown) and rating (5.0 vs 4.7). Calculator's advantage is ratings volume (365K vs 1) and iOS requirement (11.0 vs 15.5). On price there is nothing between them.

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

Thingamabob holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Calculator has 365K ratings behind it against 1, so its average is the more settled of the two.
