RPN vs Audio Selector Remote

RPN-25 CE is a photo-realistic simulation of Hewlett-Packard's highly popular scientific calculator HP-25 for the iPhone. Produced from August 1975 through 1978, it was the "Squash" member of the second-generation HP calculators known as the "Woodstock" series. It was also the first programmable calculator costing less than $200. RPN-25 CE simulates the HP-25C version released in July 1976. Its major improvement in that update was "Continuous Memory". While the simulator works just like the original calculator, a number of carefully designed extensions make it massively more powerful. Features: • Photo-realistic look • Programmable (99 or 999 steps), subroutines, conditional loops, branching • Insert and delete steps with automatic address correction • 15 user-defined function keys of up to 6 characters each, redefinable under program control • Programmable text messages • Program Auto-Start option upon loading • 100 symbolic labels • 100 visible registers, "non-volatile", with unrestricted store/recall arithmetic • 100 flags, visible at a glance • Single-step constants • Program comments • Program library with more than 150 programs pre-installed • More than 270 functions and operations not available on the HP-25 • 100 sounds built-in • Much faster than the original • "Live" register view supporting user interaction (run/stop, single-stepping) • "Live" stack view • Thousands separator (optional) • High-contrast display (optional) • Selectable pause length (up to a day) • Program listing view with program title and description • Program library view • Store, name and retrieve any number of programs • Sharing: Files, iCloud Drive, e-mail, AirDrop, Dropbox, copy, paste, print • Import and run RPN-32 CE and GO-25 programs • Run a large number of HP-41 programs with little or no changes • Clock display (AM/PM or 24h) • Supports Dark Mode Calculator functions: • Statistics, including clearing statistics registers only • Factorial for arbitrary arguments • Trigonometric functions (degrees, radians, grads) • Polar/rectangular conversions • Inverse, square root, logarithm, exponential, Pi • Percentage • Storage arithmetic (store and recall) • Extended stack operations • Low-battery warning • Sound alerts • ..and many, many more Details: cuveesoft.ch/rpn25

Audio Selector Remote is the official companion app for "Audio Selector" on macOS. Turn your iPhone or iPad into a powerful, wireless remote control for your Mac's audio environment. * Note: This app requires "Audio Selector" installed and running on your Mac to function. ◆ KEY FEATURES * Total Audio Control (Devices): Wirelessly switch between speakers, headphones, or DACs. You can change audio formats (e.g., 24-bit / 96kHz) and adjust individual device volumes directly from your iOS device. * Input Devices (Devices): Switch your Mac's microphone or line-in from the same list. Turn it on with 'Show input devices in menu' in the Settings tab. * Software Volume Control: When Audio Selector for Mac controls a DAC's volume in software (macOS 14.2 or later), you can adjust it from your iPhone or iPad like any other device. * Dedicated Volume Remote (Volume): Turn your device into a sleek, dedicated volume controller. You can even use your iPhone/iPad's physical volume buttons to adjust your Mac's audio level without looking at the screen! You can choose to show or hide the 'Mute' and 'Play/Pause' buttons in Settings → Volume Tab. * L/R Balance Control (Pro): Fine-tune your stereo sound remotely. Adjust the left and right audio balance for individual Mac output devices right from your screen. (Shown only for devices that support balance control). * Multichannel Output Pair (Pro): Choose which stereo pair - 1–2, 3–4, 5–6 and so on - a multichannel interface on your Mac uses for output. (Shown only for devices that expose multiple output pairs). * Seamless & Secure Connection (Settings): Connect instantly using Auto-Discovery on your local network, or use manual IP/Port configuration for advanced setups. Supports 'Require Pairing' for a secure connection. * Roon Zone Control (Devices): See your Mac's output devices that Roon is currently playing to - marked with a Roon badge - and adjust or mute Roon's zone volume in real time, even while Roon holds the device exclusively. Works with Roon's Device Volume and DSP Volume modes. (Requires Roon Volume Integration enabled in the Mac app.) * Pro Sync: If you are a Premium user of Audio Selector on your Mac, Audio Selector Remote will automatically detect it and provide an ad-free experience. ◆ REQUIREMENTS * Audio Selector Remote requires the 'Audio Selector' app on your Mac. * Your Mac and iOS device must be connected to the same local Wi-Fi network.
