  1. Feature A New Navigation Signal Is Already in Orbit. Can Xona Pulsar Really Replace GPS? Xona has one production-class navigation satellite broadcasting from low Earth orbit and a 258-satellite plan for what comes next. Pulsar is real, ambitious, and not yet a global GPS replacement. Here is what has actually been demonstrated, what remains a target, and why the receiver in your hand matters as much as the spacecraft overhead.
  2. Seasonal GTA VI Lands November 19 — Your Free Real-World Minimap Is Ready Now GTA VI lands November 19, 2026. Before Jason and Lucia pull us into Leonida, turn your Android phone into a free neon, heading-up real-world minimap — and give your navigation reflexes a head start.
  3. Seasonal The August 12, 2026 Total Solar Eclipse: Where, When, and How to See It (Offline) For a couple of minutes on August 12, 2026, the Moon slides dead-centre across the Sun and turns afternoon into an eerie dusk — the first total solar eclipse to reach mainland Europe since 1999. Here is where and when it happens, and how SIMT tells you the exact time and direction to look from your own backyard, with no internet at all.
  4. Seasonal How to Find Your Group in a Packed World Cup 2026 Stadium — Even With No Signal The whistle blows, the stadium erupts, you turn around — and your friends are gone. Here is how SIMT Link+ reunites your group over the local network or a private offline connection, with secure NFC and QR pairing when the stadium network cannot help.
  5. Brand What's New in SIMT 2: The Cosmos Update SIMT 2 arrives with a warm deep-space redesign and the biggest feature wave the app has ever shipped: Automations, gift views, target bulk actions and archiving, moon phases, seven UI roles, a hardened GNSS engine, and real performance gains.
  6. Evergreen The Free, Offline GeoGuessr Alternative That Works on a Plane You are 35,000 feet above the Atlantic. Your flight is six hours long. You have already watched the film and the battery on your AirPods is half dead. And then you remember: GeoGuessr costs money and needs WiFi. Here is the free, offline alternative you did not know you had.
  7. Feature Iris: AR on Any Phone, Powered by Math Instead of ARCore Most AR apps lean on ARCore and a certified device list. Iris takes a smarter route: it paints any target onto your live camera with pure mathematics, so augmented reality runs on almost any phone, works offline, and barely touches the battery.
  8. Feature What Did the Sky Look Like the Night You Were Born? Time-Travel the Solar System with SIMT's Orrery Ever wondered exactly where the planets were the night you were born, or where they will be during the next total eclipse? SIMT's Orrery puts the whole solar system in your hand and lets you drag time backward and forward to find out, entirely offline.
  9. Evergreen How to Track Satellites with SIMT: Aim a Dish, Spot the ISS, and More From aiming a satellite dish to catching the ISS overhead, SIMT turns any satellite into a direction you can actually point at. Feed it a TLE and it computes the live azimuth, elevation, and range on your device, then guides you there with the compass and Iris AR, even with no signal.
  10. Brand What's New in SIMT 1: The Constellation Update The Constellation Update is SIMT's biggest release wave to date: write on your own maps, command positioning satellites, fly through a living solar system, play GeoQuest, link multiple devices, and back everything up to Google Drive — all from one compass app.
  11. Evergreen How to Measure a Ring Size With Your Phone (No Ring Sizer Needed) You want to buy someone a ring as a surprise. You obviously can't ask for their finger size. But you can borrow a ring they already own for thirty seconds — and your phone can turn that ring into a number. Here is how SIMT's Measure tool makes your screen a calibrated caliper, and everything else it can measure once you have it open.
  12. Feature SIMT: Revolutionizing indoor & complex navigation Track+ is SIMT's answer to the places where GPS collapses: underground parking, stairwells, malls, stations, tunnels, and dense indoor spaces. It combines pedestrian dead reckoning, visual-inertial odometry, barometer altitude, magnetic and Wi-Fi fingerprinting, and beta audio stride detection into one on-device positioning pipeline.
  13. Feature How Android Raw GNSS Works — and Why SIMT Builds Its Own Positioning Engine Your phone receives timing signals from dozens of satellites every second. Most apps never touch that data. SIMT does — and it builds a full positioning engine from raw measurements, carrier phase, broadcast ephemeris, and atmospheric models to push accuracy far beyond what standard GPS gives you.
  14. Evergreen How to Find the Qibla Direction Anywhere — Even With No Internet You are in a new city, a hotel room, a mountain trail, with no signal — which way is the Qibla? Here is how to find the precise direction to the Kaaba from anywhere on Earth, with no internet, and why getting it right is trickier than most apps admit.
  15. Brand Why One App for Planning, Tracking, Measuring, and Sky Exploration Beats Four Separate Apps Most people carry four or five separate apps for navigation, measurement, local sharing, and sky tracking. SIMT combines all of those into one offline-first toolkit, and the integrated experience is better than the sum of the parts.
  16. Evergreen Offline Astronomy App for Planets, Moon Phases, Satellites, and Sky Tracking Most astronomy apps depend on a constant internet connection. SIMT calculates planetary positions, Moon phases, satellite passes, and celestial targets entirely on device, so the sky tools keep working even when you are off the grid.
  17. Evergreen Best Offline Navigation App for Weak Signal, Indoor, and Underground Use The best offline navigation app is not just one that caches maps. For weak signal, indoor, and underground use, you need fallback behavior, direction tools, target recovery, and workflows that stay useful when standard GPS breaks down.
  18. Feature Find Your Car Underground Without GPS If GPS keeps failing in a parking garage, SIMT Track+ gives you a practical way to recover your route, keep orientation, and find your car underground without depending on a stable signal.
  19. Brand What Is SIMT? The Offline-First Spatial Toolkit for Android and Wear OS SIMT is an offline-first spatial toolkit that combines planning, tracking, measurement, local sharing, Wear OS sync, advanced GNSS, automation, and astronomy in a single Android experience.
  20. Brand Introducing SIMT: The First Light Beta Before the Constellation and Cosmos updates, there was First Light: the very first public SIMT beta. Here is the foundation it laid, an offline compass and a whole toolkit for capturing, measuring, and sharing the places that matter, with every byte kept on your device.
  21. Evergreen The Word “Azimuth” Is Arabic — and So Are “Zenith” and “Nadir” Three of the most fundamental words in navigation and astronomy — azimuth, zenith, and nadir — are all Arabic. Two of them are, astonishingly, the same word. Here is the improbable journey of how humanity learned to name the invisible.
