Features: *Normal Compass(check the location shown in the bottom first. You can use the button in the bottom left to retrieve your current location) *Drawing the Ecliptic Plane, the Sun, the Moon and the planet symbols on the compass based on your location. *Showing the Sun, the Moon and other visible planets directions(azimuth) on the compass based on your location. *You can use the celestial bodies direction to confirm that the compass is pointing to the north. You can even using the celestial bodies' directions to manually rectify the compass pointing if it shows the pointer is offset by background noises. *Horoscope chart based on current time and location. *Custom time and location for the ecliptic plane view and horoscope view *10 random locations to see what the sky looks like in other locations. This is not just another compass App. Other than the normal compass feature. The Sun, the Moon and other planets' direction are also shown on the compass so that you know if the compass is affected by the background noise or not. We all know that the compass is easy to be interfered when you are inside a concrete house, near electronics or some other situations. But currently the built-in compass could not neutralize those background magnetic fields. Here comes this Ecliptic Compass app, you could use the Sun, the Moon's or even some planets' azimuth(direction) to know that if the compass is pointing to the north and you are heading to the right direction. As long as you could see the celestial bodies in the sky. Manually rectifying the compass, if you find that the Sun or the Moon's direction in the sky is offset quite a bit from the computed direction. You could use the Manual Rectification feature to temporarily to override the pointer so that your could still get the right direction. Power efficient, the app is designed to work offline most of the time. No unnecessary feature/APIs is called, No data collection. The location service only tries to get your coordinates at start-up or when you tap the big refresh button from surrounding hotspots, data or GPS. It uses data only when you want to use the map to retrieve a place's coordinates. You can also use the offline location database to search for the latitude/longitude from over 40 thousand cities and towns. Location database is provided by Simplemaps.com under Creative Commons Attribution 4.0. Colorful astrological symbols, we use astrology/astronomy symbols to show the luminaries, planets and zodiac signs. And the colors we use follow the astrological conventions. Renaissance astrological art, the twelve zodiac signs art is from the Zodiac Clock at San Marco square in Venice. Preset places, there are about 10 preset places(coordinates) at the moment which you could try and get the feeling about how the app works. Custom location and time, you could input the latitude and longitude and time to draw the ecliptic items and horoscope chart.

A speedometer you put together yourself. Set the top of the dial to match what you drive. Choose the colors that mark fast and slow. Choose what sits under the number: a live map, a g-force meter, a compass or a clock. Read it in km/h, mph or knots, in a car, on a motorcycle, on a bike or on a boat. No ads anywhere in it. No account to make. THE SPEEDOMETER Your speed fills the screen, on a dial you set up once. Choose the top of the scale to match what you actually drive, choose the colors that mark fast and slow, and switch between km/h, mph and knots whenever you like. THREE VIEWS Standard puts your speed on the dial with one panel underneath. Sport sets two panels side by side, so you can watch g-force and the 0-100 timer at once. Zen is the number and nothing else. All three work in portrait and in landscape. STYLE Four gauge styles: an arc, a full ring, segments, or a swinging needle. Three typefaces for the digits, from rounded to a seven-segment LCD, each in three weights. A single fixed color if you would rather the dial did not change. Light or dark. BUILT FOR ANY VEHICLE Car, motorcycle, bike or boat. Knots and nautical miles on the water, feet or meters for altitude, and a gauge that reads sensibly whether you top out at 30 or 300. PICK YOUR SECOND DISPLAY Choose what sits below the main gauge: - Live map - G-force meter for cornering and braking - Compass heading - Clock SPEED LIMIT ALERTS Set your own threshold. The screen edges pulse red and an optional chime sounds the moment you cross it. HEAD-UP DISPLAY Mirror mode projects your speed onto the windshield after dark, in digits you can read without taking your eyes off the road. THE NUMBERS Max speed, average speed, distance, duration, altitude, a 0-100 km/h (0-60 mph) acceleration timer, and a lifetime odometer that never resets. RECORD YOUR DRIVES Speedra can start a trip on its own once you are moving, or you can turn that off in Settings and tap Start Trip yourself. Every route is saved on your phone and stays there. Nothing is uploaded, because there is no server to upload it to, and no account to attach it to. Afterwards you can play a drive back over the map at whatever pace you like, scrubbing the speed profile, reading the elevation underneath, or jumping to the fastest point of the run. SHARE THE DRIVE Turn a replay into a short video, or a clean stats card, ready for Messages and Instagram. Export the track as GPX for another app, or import a route someone sent you and replay it here. ON THE LOCK SCREEN Your speed carries on updating on the Lock Screen and in the Dynamic Island, so you can check it without unlocking anything. PRIVACY Speedra never asks for the Always location permission, only While Using. Your location is used to draw your speed and nothing else. There is no account, no analytics on where you go, and no server behind the app at all. FREE TO USE The speedometer, all three views, all three units, head-up display mode and GPX are free forever, along with your recent drives and your first replays. Speedra Pro opens every drive you have recorded, plus the second display, speed limit alerts, the gauge styles and digit faces, your own scale and color zones, and your speed on the Lock Screen.
