# IP Keypad vs Dev Calc

The clearest difference is rating: IP Keypad at 4.7 against Dev Calc's 2.0. IP Keypad also leads on in-app purchases (none vs 1) and ratings volume (141 vs 2). Dev Calc's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 26.0). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. Dev Calc sells 1 in-app purchase, starting at $1.99 per month. IP Keypad asks for nothing beyond the download.

IP Keypad holds the better App Store score, 4.7 against 2.0. That said, the two scores are not equally well evidenced: IP Keypad has 141 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 75% of IP Keypad's written reviews are positive against 60% of Dev Calc's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 17, 2026 and October 7, 2026 respectively.
