IP and Subnet Calculator Pro vs DM50

This app is used to calculate IP address and subnet. It is simple and easy to use. Features: • IPv4 Address - Support the input data: Subnet Mask, CIDR Notation, Wildcard Mask, Hosts requirement - Swipe on screen Left or Right to move to Adjacent Network - Swipe on screen Up or Down to see Decimal IP Address or Binary IP Address - Check and correct when the data inputs not correctly. • IPv6 Address - Support to calculate with: Prefix Mask, Subnetwork Prefix - Swipe on screen Up or Down to see Expanded IP Address or Compressed IP Address - Swipe on screen Left to move to next Subnet Address with Subnetwork Prefix - Check and correct when the data inputs not correctly. • Tool convert from IPv4 to IPv6 - Support to convert IPv4 to IPv4-Mapped IPv6 Address and 6to4 Address. This tool is absolutely useful for IT engineers or anyone study about IP network and Subnetting. For any question or idea, feel free to write a review or mail to contact.miniapps@gmail.com.

DM50 is a faithful tribute to the golden era of scientific calculators, bringing the legendary HP-style experience to your iPhone with modern enhancements. Whether you're an engineer, student, scientist, or calculator enthusiast, DM50 delivers the power and precision you need, with the tactile familiarity of classic RPN entry and a crisp, authentic 132×64 monochrome LCD display. REVERSE POLISH NOTATION (RPN) A true HP-style RPN engine with a dynamic multi-level stack, stack lift, SWAP, ROLL and DROP. Once you learn the flow, complex calculations become faster and more intuitive. ALGEBRAIC MODE (CAS) Type expressions the way you write them: full operator precedence, parentheses and implicit multiplication (2π, 3(4+5)). Includes numerical derivatives ∂(f,a), definite integrals ∫(f,a,b), and nine memory variables (x, y, z, A–F) for chained calculations. EQUATIONS AND INEQUALITIES Solve linear and quadratic equations — complex roots included — and linear inequalities. MATRIX ALGEBRA Matrices up to 5×5 in a dedicated editor: addition, subtraction, multiplication, transpose, trace, determinant and inverse. MORE MATH MODES • 3D vector calculations • Complex number arithmetic • Base conversion: decimal, binary, octal and hexadecimal • Formula library with pixel-art diagrams, inspired by the classics • Constants library with common physical and mathematical constants SCIENTIFIC FUNCTIONS • Trigonometry with RAD / DEG / GRAD angle modes • Logarithms, exponentials, powers and roots • Hyperbolic functions, factorials and more AUTHENTIC EXPERIENCE • Pixel-perfect monochrome LCD rendering (132×64) • Classic keyboard layout with BLUE / ORANGE • Real-time status bar: clock, angle mode, modifiers and battery • Retro sound effects BUILT FOR POWER USERS DM50 is designed for depth. The layered modifier system exposes dozens of functions without cluttering the interface — just like the classic calculators it draws in A LITTLE FUN TOO A built-in dice game to take a break between calculations.
