The 6502 microprocessor changed the world. Released in the 1970’s, it was the reason that home computers were within the reach of many hobbyists. This app re-creates the 6502 CPU and some of the hardware that used it. This isn't a game (although games are included), this is an emulation of the 8-bit processor, complete with an assembler and some programming puzzles to solve. Start with the most basic user interface you can imagine - six 7-segment LEDs and some buttons - to enter, debug and run your applications. Then upgrade to a display and keyboard, and use the built-in monitor program to dump memory, makes edits and execute your code. Can you run BASIC? Maybe. FORTH? Perhaps. Assembler? Definitely! Don't think of this as a something "fun" or "enjoyable" in the traditional sense. Think of it as a puzzle: how on earth did those folks in the 1970's manage to do ANYTHING when computers were this basic? Documentation is provided, but to get the most of out of this app you'll need to do your own research. Just like in the 1970s. Features - KIM-1 keypad/LED mode simulator. - KIM-1 serial terminal mode simulator. - Apple 1 serial terminal mode simulator. - Multiple programs including Life, Mastermind, word games, Trek, and more. - Working 6502 Assembler with single-step, memory and register view. - A comprehensive 6502 tutorial system with interactive lessons and reference material. - Shareware! All features are always available without a purchase.

DeepSpace — Star & Planet Viewer Point your phone at the sky and see the stars move in real time. DeepSpace turns your device into a personal star atlas — no account, no subscription, no internet required. What's in the sky tonight? Hold up your phone and explore 95 named stars rendered in color by spectral type, all 8 planets, the Sun, and the Moon — their positions calculated from simplified orbital models and updated live. Accurate enough for casual stargazing and learning the sky; not a precision instrument. Features • Gyroscope sky map — point anywhere and the stars follow, at up to 120fps on supported devices • 16 constellations — tap any to see its mythology and star pattern • 110 Messier objects — galaxies, nebulae, and clusters plotted and tappable • Tap to lock on — tap any star or planet for its magnitude, coordinates, spectral type, and more • Sky search — find any object by name and jump to it instantly • Tonight's Sky — one tap shows what's visible right now: planets above the horizon, best deep-sky objects, and current moon phase • Time Machine — scrub forward or backward in time to plan or revisit a night • Observation journal — log your sightings with date, location, and notes • Celestial event alerts — get notified about oppositions, conjunctions, and lunar events for objects on your watch list • Milky Way overlay — the galactic band drawn across the sky • Red Night Mode — full red filter to protect your dark-adapted vision at the eyepiece • Share the sky — share a snapshot card of tonight's sky with friends • Portrait and landscape — works in any orientation on iPhone and iPad Honest about accuracy Star and planet positions use simplified orbital models this is great for finding constellations, identifying planets, and learning the night sky. For precise observation planning, pair it with a professional ephemeris.

Verdict
The clearest difference is price: VirtualKim at Free against DeepSpace's $0.99. VirtualKim also leads on ratings volume (29 vs 1) and iOS requirement (17.0 vs 26.0). DeepSpace's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.8). On update cadence, ads and device support there is nothing between them.
