Yonder is a long-range shooting trainer: not a shooting game, and not a ballistic calculator. The ballistics are validated against Doppler-radar-derived drag data, and you do the work a shooter does. You range a target through a precision reticle, build the firing solution, dial or hold your elevation, read the wind, and send it. Then you watch the trace and see exactly where the round went. It all comes down to the first-round hit. No sighters. No walking it in. Just the cold bore shot, as many times as you want, anywhere, in any conditions you choose. DON'T TAKE OUR WORD FOR IT. BRING YOUR DATA. Yonder runs a Modified Point-Mass solver with G7 drag, real atmospheric modeling, spin drift, Coriolis, and aerodynamic jump. It is validated against Hornady's 4DOF Doppler model to within 0.02 mil on multiple match loads out to 1,100 yards. At 1,000 yards that is under three-quarters of an inch. Check it against your own DOPE book, line by line. If our numbers don't match the ones you have for your rifle, we want to hear about it. COLD BORE, THE DAILY One shot. Everyone gets the same one. No second tries. Hit it, keep your streak, and see where you landed against everyone else who took it today. THE SKILLS • Range unknown-distance targets off the reticle, then dial or hold the come-up. • Read the crosswind and hold or dial your windage. • Keep the rifle level with the on-screen bubble (it reads your phone's tilt). • Every skill has its own switch (wind, cant, advanced drift), so you can isolate the exact thing you want to drill. THE GEAR • First- and second-focal-plane glass: 62 first-focal-plane scope bodies, from a 1-10x LPVO to a 5-45x, where the reticle grows and shrinks with the zoom, plus second-focal-plane scopes where it stays one size and reads true at a single magnification, the way real glass of each kind works. • A reticle library built from published subtensions: mil-dot, tree grids, fine mil rulers, chevron BDCs, and a clean second-focal-plane hunting duplex. • A full cartridge and load library with DOPE cards, plus in-app BC truing for your exact handload. MORE WAYS TO SHOOT • Know-Your-Limits, Texas Star, PRS Skills, and Speed Steel stages. • Hunting scenarios on big-country habitat backdrops. • Hostage and no-shoot discipline targets. • DOPE-from-memory, wind-call, and max-point-blank-range fundamentals drills. • Shot-clock pressure with per-scenario stats. • Head-to-head pass-and-play on a single device. THE ACADEMY Takes you from "what is a mil" to reading a DOPE card and calling wind. Dozens of lessons across eight units, with graded gates and a final capstone shot. No account required. FREE AND PRO The core loop is free: practice, fundamentals drills, the daily, and Academy foundations. Yonder Pro unlocks the full scope, reticle, and cartridge library, every drill and stage, and custom loads. Yonder Pro is offered as a monthly or annual auto-renewing subscription, or as a one-time lifetime unlock. Prices are shown in the app before you buy. Payment is charged to your Apple Account at confirmation. A subscription renews automatically unless auto-renew is turned off at least 24 hours before the current period ends, and you can manage or cancel it in your Apple Account settings. PRIVACY No ads and no account. Your profiles, scores, and progress live on your device, and the trainer runs fully offline. The daily board uses an anonymous handle. We never track you across other apps or sell your data. IMPORTANT Yonder is a training and entertainment simulator. It is not a firing solution for live fire. Always verify real-world data against your own equipment, conditions, and a qualified source.

November 1941. The Strait of Gibraltar. You command a Type VIIC U-boat: 67 metres of steel, four bow tubes and one at the stern. On the horizon, smoke from a convoy: five freighters and a tanker, guarded by a destroyer and two corvettes. Your mission: sink as much tonnage as you can and make it home alive. UBOOTSIM is a World War II submarine simulator made to be enjoyed at your own pace. Every attack is a small game of chess between you, the convoy and its escorts. HUNT - Attack periscope and bridge binoculars, with 1.5× to 6× zoom, a bearing scale and an automatic 360° sweep. - A living daylight sea: swell, whitecaps, clouds, sun glitter and funnel smoke that gives the convoy away long before its hulls. - Hydrophone to hear propellers while submerged: slow, heavy merchants and fast escorts. An audible alarm sounds for every new contact. - Tactical chart of the Strait with its coastline, grid, bearing ring, contacts and wakes. Tap a point and the helm and periscope turn towards it. STRIKE - Lock the target, take bearing and range marks and let the Torpedo Data Computer (TDC) find the solution. When the button turns green: fire! - Fine-tune the target's range, course and speed by hand, or switch on the automatic TDC for a more relaxed game. - Spreads of 1, 2 or 4 torpedoes, a stern tube and real-time reloading, one tube at a time. - Follow every torpedo with its wake, its countdown and a tracking window that zooms in for the last seconds. And, just as in 1941, some pistols fail. - On the surface, the 8.8 cm deck gun: tap the ship, wait for the green ring and fire. The crew corrects their aim with every hit. SURVIVE - After the first hit the convoy raises the alarm, turns and speeds up, and the escorts come after you with ASDIC and depth charges. - Go below the thermal layer, run silent, change course after every pass and keep an eye on your hull and battery. - Underwater side view: your U-boat angled as it dives, enemy hulls above you with the metres beneath their keels, and depth charges falling and bursting all around. - While you run on the surface a patrol aircraft may appear. If it spots you, it attacks and radios the destroyer. Dive in time… or shoot it down with the deck gun. A SUBMARINE YOU CAN FEEL - Diving depends on your speed: at full ahead the boat dips its bow and goes down at an angle; stopped, it barely sinks. - Alarm bell and the call of "Dive! Dive!" as you submerge, and "Surface! Surface!" as you come up. - Diesels rumbling on the surface and electric motors humming underwater, higher-pitched the faster you go. - The blast of compressed air at launch, the whistle of running torpedoes, explosions, ASDIC pings against the hull and depth charges that grow louder the closer they burst. SHIPS WITH CHARACTER - Freighters from different shipping lines, with coloured funnels, lifeboats and cargo derricks. - A long, low tanker: the big prize. - A fast, camouflaged destroyer with four guns, and two corvettes that never stop circling the convoy. - The more you zoom, the more you see: windows, flags, pennant numbers on the bow and fires when you hit them. FOR EVERY COMMANDER - Time compression from 1× to 32×, dropping back to 1× automatically at any danger. - "Show all ships" mode to learn the game. - Built-in quick guide in English and Spanish. - Scalable display: stretched to fill the window or proportional, as you prefer. - For iPhone, iPad and Mac, with a native Mac version and keyboard controls. Ship names are fictional. UBOOTSIM is a game: it simplifies reality to make it playable, while staying true to how war at sea was fought in 1941. Good hunting, Commander!
