Particle Detector vs SwiftRPN

Particle Detector turns your iPhone, iPod Touch, or iPad into wireless, Bluetooth Low Energy scanner that may be used to find iBeacon™ and Eddystone beacons. Once discovered by UUID, Particle Detector displays Major ID, Minor ID, Signal Strength, and timestamp for last moment of discovery. New UUID filters may be added for quick discovery. Eddystone beacons in the display will show signal strength, calibrated Tx power, broadcast URL, and battery life (if supported by the beacon). Designed exclusively for iOS7 or greater, this app allows your iOS device to discover other iOS devices acting as iBeacon™ or custom hardware devices that support iBeacon™, including those available for purchase on our website. NOTE: Particle Detector will continue to log iBeacon ranging information, even while backgrounded. Continued use of GPS running in the background can dramatically decrease battery life. "iBeacon" is a trademark of Apple Inc., registered in the U.S. and other countries.

SwiftRPN is an RPN (Reverse Polish Notation) calculator that aims to be quick to open and easy to use. = RPN Stack Work quickly and efficiently using the RPN Stack by pushing and popping values. The stack will always show what series of inputs led to each output, so you won't lose context during complicated expressions. = Extended Types SwiftRPN can understand scalar types like integers and real numbers, as well as vectors and square matrices of sizes 2, 3, and 4. When operating purely in the scalar integer domain, SwiftRPN can promote up to BigInts to avoid floating point imprecision. = Operators SwiftRPN has 84 built-in operators with included documentation and examples. All the expected operators (basic arithmetic, exponents, logarithms) are present, as are: - Rounding functions (floor/ceil/trunc/round) - Unit conversions - Bitwise operations (and/or/not/xor/shift left/shift right) - Statistics (avg/min/max/sum/std dev/NPV) - Trigonometry (sin/cos/tan + arc/hyperbolic variants) - Vector operations (dot/cross/normalize/length/swizzle) - Matrix operations (identity/inverse/transpose + translation/scale/rotation matrix generators) = Unit Conversions SwiftRPN has 74 built-in units, and can convert between units within families, including: - Angle - Area - Colors (3 and 4 components) - Coordinate systems (2D and 3D) - Length - Mass - Storage (Base 10 [SI, 1000 bytes in a kb] and Base 2 [1024 bytes in a kb]) - Temperature - Time - Volume = Value Representation SwiftRPN recognizes values represented in binary, octal, decimal, and hexidecimal. You can: - Enter values in one representation, and convert them to another - See the result of bitwise operations in binary automatically - View vec3 and vec4 components (truncated) in hexidecimal when working with colors.
