Focus Monke vs XEQ41

Your focus grows a tiny ocean. Focus Monke is a pomodoro timer with a heart. Every focus session is a dive: press start and Monke, a little guy in a big brass diving suit, takes his submarine down. He stays down as long as you stay focused. Surface at the end, and the reef you're building is a little more alive than you left it. HOW A DIVE WORKS - Pick your time, press START. That's the whole job. A classic 25-minute pomodoro, a two-hour deep session, whatever the day needs. - Your distracting apps go quiet. Focus Monke uses Apple's Screen Time to block apps for exactly as long as you're diving. When you surface, they come back. No willpower required. - Finish the dive and the good part happens: bananas, a spin of the bonus wheel, and sometimes a brand-new fish. BUILT FOR DISTRACTED BRAINS If your brain treats "just five minutes of scrolling" as a legally binding contract, welcome aboard. Focus Monke was made for the easily distracted, ADHD very much included. Short sessions still count. Rewards land every single time, not someday. No shame, no productivity sermons. Just a monke who believes in you. YOUR REEF Every fish in your aquarium was earned by focusing. Commons, rares, a few legends from the deep. Each one is hand-drawn and swims around your reef like it has somewhere to be. Feed them bananas. Name your tank. Take a selfie with Monke. It's your ocean, and you made it out of homework. DIVE TOGETHER Focus is easier when someone else is also focusing. Join a session and your monke takes a seat in the sunken ship alongside up to nine other divers, timers running, everyone quietly at work. Dive in at 2am and there's still a crew to sit with. Nobody can message you. Nobody can distract you. Just the quiet, specific comfort of a room where everyone is doing the thing they came to do. Leave whenever you like. The ship keeps sailing. DRESS UP YOUR MONKE Tap Monke and the dressing room opens. Hats, hair, glasses, beards, earrings, costumes, backgrounds, and diving gear that gets stranger the deeper you go. Every item is bought with bananas, and bananas come from focusing. There is nothing to buy with real money in there, ever. Your look follows you into the submarine, onto your stats, and into the ship next to everyone else's. STREAKS WITHOUT GUILT Show up and your streak grows, with milestones actually worth reaching. Miss a day and nobody yells at you. The reef is the reason to come back, not a red badge. CERTIFIED DIVER Focus Monke is free to use. Going Certified supports one small developer and one small monke, and unlocks: - 3x bananas and bigger bonuses after every dive - Choose exactly which apps get blocked, or let a dive block them all - The gold diving suit (Monke looks fantastic in it) - Special items in the shop And thanks to Certified Divers, there are no ads. For anyone. Ever. Certified Diver is available as an auto-renewing subscription (monthly or yearly) or a one-time lifetime purchase. Subscriptions are charged to your Apple Account and renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in Settings > Apple Account > Subscriptions. GOOD QUESTIONS - Does it work offline? Yes, everything except group sessions. Airplane mode is honestly great for focusing. - Do I need an account? No. Open the app, start a dive. - Where does my data go? App blocking runs entirely on your device through Apple's own Screen Time. We never see what you do on your phone, and nothing is sold to anyone. Group sessions share just what the crew can see: your diver name, your flag, your monke's look. THE SMALL PRINT, WARMLY Hand-drawn art. One developer. One monke doing his best. If Focus Monke helps, tell a friend. The reef grows one dive at a time, and so does this little app. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://focusmonke.com/privacy.html

XEQ41 is a hand-written emulator of a 1983 programmable RPN calculator, running the original manufacturer's microcode on a simulated NUT processor. It is not a re-implementation of the machine's behaviour — it is a simulation of its processor, so the calculator on screen executes the same instructions the hardware executed, and does what the hardware did for the same reasons. THE DETAILS THAT GET TESTED • Hold a key too long and the microcode itself cancels the function and prints NULL. That is 7,100 instructions — 1.23 seconds at original speed. Nobody wrote a timer; the ROM does it, and it stays 1.23 seconds when you run the machine faster. • BEEP is four tones, not three: 578, 361, 722 and 578 Hz, because the microcode falls through into a fourth. The test was written expecting three and the machine corrected it. • The display is modelled as a liquid crystal panel rather than sampled as a register, so the half-built strings the hardware never showed stay hidden and the 174 ms blink it does intend does not. • Continuous memory. Close it, force-quit it, come back next week — it is where you left it. • Shift-ON puts up a running clock, exactly as the manual says. THE FACEPLATE IS DRAWN, NOT PHOTOGRAPHED Thirty-nine moving key caps, the glass and the annunciator row are all vector, generated from a measured coordinate table — sharp at any size, with no image assets anywhere. A key going down travels, closes the shadow beneath it and darkens. The fourteen-segment display face is ours outright, drawn from our own segment table, so no third-party font ships. Every key is an accessibility element whose label is composed from the printed legend, so VoiceOver says "x squared" where the plate prints x². WHAT IS IN IT • FOCAL programming, with program files in and out through Files • Extended Memory, with real file structure • Four ports for plug-in module images you supply • The 82143A thermal printer and its paper tape, once you supply its ROM image • Synthetic programming — the byte grabber runs • Saved machines that record what was plugged in and refuse to open as something else • Alarms, the clock, BEEP and TONE, LCD contrast, haptics • Fifty transcribed keyboard overlay cards • Three faceplate palettes, and an optional extra display for the stack or the machine's status • Seven FOCAL programs written for this app, free to use and modify HOW IT IS CHECKED Thirteen scripted scenarios run byte-identical against a second, independent implementation of the same processor. Six programs from printed sources reproduce their published answers, including a polynomial fit and a singular linear system whose correct answer is the degenerate one. All thirty coordinates of a published planetary ephemeris match to the seven digits the display carries. 673 tests. PRIVACY There is no networking code in the app at all. No account, no analytics, no advertising, no tracking, nothing collected. Everything stays in the app's own storage on your device. WHAT IT IS NOT It is not a general-purpose calculator — it is one specific machine, and if you have never wanted that machine it has nothing to offer over the one already on your phone. Third-party module images — the printer's ROM among them — are yours to import, not ours to distribute. COMPATIBILITY XEQ41 is functionally equivalent to the HP-41CX.
