StarMap3D itself works pretty good. tracking is decent, plenty of data. i wish the time slider was a little more intuitive. there isnt much support for comets or asteroids but thats ok. the bad thing that happened, is that StarMap3D has accessed my calendar and jam packed it with every single upcoming moon phase and astronomical event for the next 1000 years. this wouldn’t be so bad- in fact, it would be pretty neat- if it weren't for the fact that every event was added precisely FOURTEEN TIMES. my calendar is utterly filled with endless identical entries, thereby making it difficult to find other calendar events of mine. furthermore, even after revoking the apps access to the calendar and even deleting StarMap3D altogether, the redundant entries are still there. i would have to go along and delete them manually, one at a time- which would likely take several lifetimes. so, i will have to live with this and be content to be emphatically over informed about every single upcoming and passed astronomical event, for the rest of my natural lifespan
