Essential developer utilities in one app. Programmer's calculator, bit toggle, subnet tools, SCPI generator & more — actively growing.
Coder's Friend is a focused toolkit for developers, engineers, and makers — built for quick access to the everyday utilities you actually need. The app is actively developed and regularly updated with new tools and features.
Programmer's Calculator Work with numbers across HEX, DEC, OCT, and BIN. Perform arithmetic and bitwise operations (AND, OR, XOR, NOT, shifts) directly in your preferred number system.
Bit Toggle Visualize and manipulate individual bits across 8 to 64-bit values. See how flipping a single bit changes the result — perfect for register configuration, bitmask debugging, and low-level protocol work.
Subnet Calculator Enter any IPv4 address and CIDR prefix to instantly see network address, broadcast, host range, subnet mask, and wildcard mask. No more manual calculations.
Timestamp Converter Convert between Unix timestamps and human-readable dates. Supports seconds and milliseconds, multiple time zones, and shows detailed breakdowns including day of year, week number, and ISO 8601 format.
SCPI Generator Build instrument command sequences visually — no need to memorize SCPI syntax. Choose from ready-made actions for Digital Multimeters and DC Power Supplies, configure parameters, and get validated SCPI-99 output you can copy directly. A built-in state machine validator checks your sequence for errors and warnings before you send anything to your instrument.
History Every calculation, conversion, and SCPI sequence is automatically saved. Tap any history entry to restore the full state and pick up right where you left off.
Clean, fast, no ads, no tracking. Just tools that work — with more on the way.
