IPMask vs CIDR
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
IPMask
This utility helps calculate IP network addresses and subnetworks for IPv4. It assists in understanding IP addressing functions like host identification and location addressing within a network. The tool is useful for dividing networks into smaller subnetworks through subnetting.
- IP network address calculation
- Subnetwork subdivision
- Host identification
- Location addressing
- IPv4 support

IPMask works out an IPv4 network from an address and a mask: network and broadcast address, first and last host, number of hosts, netmask and wildcard. • Type the address the way you have it: 192.168.1.1, 192.168.1.1/22 or with a dotted mask. • Move the mask slider and watch the 32 bits split into the network part and the host part. • See the address type at a glance: private, public, loopback, link-local, multicast. • Switch to the binary view to see the address, netmask and network bit by bit. • Copy the whole result as text or share it. • On Apple Watch: enter an address with a keypad, turn the Digital Crown to set the prefix and read the result on your wrist. /31 point-to-point links (RFC 3021) and /32 host routes are handled correctly. Made for network engineers, students and anyone who sets up a router at home. The app works offline; it needs a connection only for the small ad banner.
CIDR
This utility calculates IP address ranges from an IP address and subnet mask. It supports IPv4 calculations, including prefix display, address range counts, and bit notation. Useful for quick CIDR notation checks and subnet mask conversions.
- IP address range calculation
- Subnet mask to CIDR conversion
- IPv4 prefix display
- Number of address ranges
- Bit notation display
- Quick reference table

Calculate the IP address range from the IP address and subnet mask. It can be used to calculate IPv4 addresses, including prefix display, number of address ranges, and bit notation. CIDR calculation, when you want to check CIDR notation quickly. To convert subnet mask to CIDR notation. It can also be used as a quick reference table for subnet masks. Bit notation is also available, so it is suitable for learning IPv4.

Verdict
The clearest difference is in-app purchases: IPMask at none against CIDR's 1. CIDR's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 5 months). On price, rating, ratings volume and monetization model there is nothing between them.
