Why limit yourself to your small screen on the phone? Run PolarAligner Pro (Astro Tool), an app by Kechkoindustries, best experienced on your PC or Mac with BlueStacks, the world’s #1 Android emulator.
PolarAligner Pro is one of those small astronomy tools that focuses on a single job and keeps it simple. It helps line up an equatorial mount in either hemisphere, with a built‑in compass and a spirit level so the mount gets leveled and pointed the right way. The compass can use magnetic north or true north, and you can set declination either manually or let it calculate true north offline with no internet. The level can be calibrated against a real spirit level, which makes it surprisingly accurrate for a phone. There is also a daylight alignment mode, so setup does not have to wait for darkness.
What stands out is the Polaris view. It grabs GPS for latitude, longitude, and altitude, then shows a clear graphic of where Polaris should sit, the hour angle, and the numbers that actually matter. There is a quick drift alignment guide and a calculator to help nudge azimuth and altitude with as little error as possible. The app includes reticles for a bunch of polarscopes like iOptron, Sky‑Watcher, Sky Adventurer, Orion, Meade, Vixen, Takahashi, Celestron, Bresser, and Astro‑Physics, so the overlay looks like the scope already on the mount. There is even a manual if someone wants the details.
Heads up though, the compass and level rely on hardware sensors. If the phone or tablet does not have a magnetometer and a tilt sensor, those tools will not work, which is why some reviews look rough. That is a hardware limit, not the app being broken. On a PC with BlueStacks, the big screen is great for reading the charts and reticles and setting location, but most desktops do not have those sensors either, so treat it more as a planning and reference tool at the desk, then take the numbers outside.
