Planisphere

Downloaded this app for my astronomy lab. Cool app, everything is really clear, but the GPS function does not work. My phone's GPS is completely functional when I use maps, compass, etc., but not when I use this app. I'll point it clearly at one constellation and it will give me a completely different one. No complaints about anything else in the app. If this one fix is made, it'll be perfect.

I play around with this with my grand kids. It teaches them while having fun. Great app

This is a great app to play around with! Works great! I just wish I could choose a specific date to view directly instead of going hour by hour into the future or past. Other than that minor issue, I love it!

The idea is great but the calibration is inaccurate and there is no option to recalibrate at will. If calibration issues are fixed I would highly recommend this to friends. I hope to see some updates.

Totally awesome :D nice features

It's works, not a super awesome app, but for 99cents it's good. If you have an astronomy class it comes in handy or if you just like to know what's above you.

The compass function displays incorrectly

Does what it says. Lot's of layering options including deep sky objects so you can focus on what you want and leave out the other stuff. Very reasonable price. Nightlight. Nice job. I recommend it. Made for someone that will use it in the field.

YOU have to update the time manually by going into the settings. The graphics, zoom function, and other features are first rate for a no-cost download. It sure beats carrying around one of the plastic plansipheres! But back to the major issue I have with this app. Step 1: Set your Location Step 2: Set current/use device time Step 3: Exit to the planisphere(main) window. Suppose it's 8:00AM in Chicago on August 23rd. The planisphere displays accordingly. But now you want to see the sky in the Philippines - where you know its after dark. So you look up "Manila" in the location list, select it, and exit back out to the planisphere. Instead of a dark sky correctly showing what is overhead for the Philippines at 8PM - you see what 8:00AM would look like from that country! What the . . .?! Budapest Hungary: Same thing - except at 8AM there the sun(and the ecliptic) are much lower in the sky than in Manila. BUT - don't forget - while you were looking at the sky you pulled up at 8AM the time has become 8:06! Oops, gotta go back into the Settings and touch Time Now again! And now you can see what the sky looks like at 8:06AM in Paris, Rio De Janeiro, Tokyo, or anywhere your heart desires. Come on!! So basically this is just like the plastic plansiphere you may have had in school or seen in a nature shop - plastic horizon simulating your latitude, with disk below with all the stars and coordinates on it - that you have to set yourself! Otherwise, I'd give it five stars.
