Drone Pilot Guide vs MainframeMonitor

Every drone pilot needs one reference on their phone — this is it. Browse full spec sheets for popular consumer drones, work through pre-flight tutorials, and run a smart checklist before every take-off, all in a clean, offline dark-mode app. Most drone apps are built for a single aircraft. This is a pure pilot's companion: a model library you can browse by series, practical flight tips, and a cockpit HUD you can explore — no drone required to learn your way around it. — WHAT YOU GET — - Full spec sheets for popular consumer drone models across the Mavic, Mini, Air, Phantom, Inspire, Avata, Flip and Enterprise families - A model library organized by series so you compare flight time, range, top speed and camera at a glance - Step-by-step flight tutorials covering pre-flight prep, in-air safety and cinematic filming - A pre-flight checklist for battery, storage, compass and airspace so nothing gets missed before take-off - A cockpit HUD you can explore — aperture, ISO, shutter, EV and white balance settings alongside battery, GPS, altitude, distance and speed readouts - A daily pre-flight reminder plus metric or imperial units, all working fully offline — PERFECT FOR — - Recreational pilots who want a quick model reference at the field - Beginners building safe, repeatable flight habits - Aerial shooters learning what each camera setting does before they fly - Buyers comparing drone models before a purchase — WHY NOT JUST SEARCH THE SPECS ONLINE? — Because at the field you want one clean, offline place — models, tutorials and your pre-flight checklist side by side, not a dozen browser tabs and ads. Everything here is bundled on-device and ready even with no signal. — PRIVACY — No account, no tracking, no sign-up. Every spec, tutorial and checklist lives on your device, and reference content needs no internet at all. — FULL ACCESS — Full access unlocks the complete model library, all flight tutorials, the pre-flight checklist and the cockpit HUD. It's available as a weekly plan, a yearly plan, or a one-time lifetime purchase — your choice, no lock-in. Grab the app, run your first pre-flight checklist, and fly with confidence.

MAINFRAME MONITOR: Your Device as a Mainframe Console Mainframe Monitor shows your device's real live data in the style of a 1980s IBM operator console: CPU, memory, storage, battery, network, thermal state and motion. All values come from your device. You also get green phosphor text, scanlines, key clicks and real MVS commands. REAL DATA, CLASSIC LOOK • Live CPU load per core, memory, DASD, battery, network and thermal state • Front panel lamp strip that flickers with the load • Seismograph as a moving paper strip. Knock on the table! • Compass, audio output, brightness and refresh rate (ProMotion) • Motion sensors with pitch, roll, yaw and G-vector • Capacity planning: battery time remaining and storage forecast • Session statistics (SMF) with averages and peak values • Clock with UTC, Julian date and 64-bit TOD register FIVE HISTORIC DISPLAYS Press PF5 to switch between green and amber phosphor, the IBM 3279 color terminal, the neon-orange IBM 3290 gas plasma display and the Tektronix 4014 storage tube. Each display has its own effects, from degauss to beam redraw, and a matching app icon. MVS CONSOLE WITH REAL COMMANDS In the syslog you enter commands like a real operator: D T, D A,L, D M=CPU, D U,DASD, D NET, D IPLINFO, D ENV, D CAPACITY, D M=MIPS (CPU benchmark) and many more. With PF8, a virtual IBM 1403 line printer prints a status report on continuous paper that you can share as an image. PARALLEL SYSPLEX Couple iPhone, iPad and Mac on your local network via Bonjour to form a sysplex. The sysplex panel shows CPU, memory and battery of all devices. TRACE ROUTE WITH WORLD MAP PF9 traces the path your data takes to any website. You see every hop with IP, location and round-trip time, plus an ASCII world map of the route. The optional latency panel measures ping, jitter, packet loss and clock drift. IPL, INTRO AND SCREENSAVERS At startup the system boots with an authentic IPL sequence. The screensavers show real values too: control panel, tape drives, core memory, punch cards, printer or oscilloscope. GAMES IN THE COBLIB Hamurabi, Void Patrol, Snake and Bagels: classics in terminal style. WIDGETS AND LIVE ACTIVITY • Widgets for the Home Screen and Lock Screen in three sizes • Control Center button • Live Activity in 3270 style on the Lock Screen and in the Dynamic Island FOR EVERY DISPLAY The layout adapts to iPhone, iPad, Mac and foldable devices like iPhone Duo, stacked or side by side. With a hardware keyboard, F1 to F12 work as PF keys. FULLY CONFIGURABLE Show, hide and reorder panels, or choose a preset: Default, Minimal, Performance, Network or Device. Under PF1, an operator guide in German and English explains every feature. PRIVACY No tracking, no ads, no analytics. The app works offline. Network features only start after you agree (message IEA910A), and you can withdraw consent at any time under PF7. The EXT lamp shows you when data goes to the internet. Note: Job names in the log are simulated. D M=MIPS is an estimate, not an official IBM rating.
