Release 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.
Track+ deep dive
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.
GNSS deep dive
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.
Why one app beats four
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.
Astronomy guide
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.
Offline navigation guide
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.
Track+ guide
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.
Core guide
SIMT is more than a compass app. It is an offline-first spatial toolkit that combines planning, tracking, measurement, local sharing, Wear OS sync, and astronomy tools in a single Android experience.
Use cases and feature depth
Use this blog to understand which SIMT feature fits your situation, whether you are trying to find a car underground, coordinate over the same local network, measure a room, follow planets and satellites, or keep your data private by default.
