UnivMap is a navigation app. Search for places, get directions, and check your estimated time of arrival. -Search Type in where you want to go. Alpha Centauri, the Orion Nebula, or that black hole at the center of the galaxy. -Directions Starting from your current location, UnivMap works out the distance and arrival time — and kindly routes you around interstellar pirates and high-radiation zones. To Voyager 1: 25.599 billion km, about 23 hr 43 min at the speed of light. It never stops moving, so we time it just right — it reaches the destination to meet you the moment you arrive. -Choose how you travel Rocket, car, bike, or on foot — take your pick. Drive to Mars and the route card will warn you it's uphill the whole way. -Save your places Set your Home and Work, and get directions home with a single tap. -Reviews Every place has ratings and reviews. The Moon currently holds 5.0 stars across three reviews — one visitor wrote: "That's one small step for a man, one giant leap for mankind." -Works offline No connection required. No data collected. -Search galaxies, get directions, check your ETA. The nearest neighbor is over four years away — pack snacks.

Verdict
The clearest difference is in-app purchases: UnivMap at none against My Sky's 1. UnivMap also leads on update cadence (every 9 days vs every 3 months) and device support (3 vs 1). On price, ads and iOS requirement there is nothing between them.
