Thank You!
Thank you so much Jose R. Torres for creating these detailed and beautiful maps and making them available free. Also many thanks to Norbert Schmidt for developing this very useful app.
The maps are very detailed and easy to use. I really appreciate the switch to red for night vision. Mostly though the fact that I can flip the map inverted for my Newtonian and flip right to left for my refactor or Maksutov telescopes is the best part. This enables me to duplicate the field I am seeing in the eyepiece and compare it with the map field. The fact that the maps are detailed enough makes this all work.
The app works smoothly easily and is not glitchy making this a solid and dependable package I enjoy using with one of the most detailed star atlases available.

Excellent App!
The Triatlas is one of my favorite sky atlases. I like having the app so I only need to print the 50 or so pages of the "A" set, and I can access the other two sets when I am outside with my telescope. I really enjoy being able to turn the brightness way down and turn on red on black to preserve night vision. After using it, I tend to wait a while before starting a new sketch for my eyes to get rid of the faint light.

TriAtlas
Simply the best and greatest 'free' astronomy star chart download available on planet Earth, the Solar System, the universe...
Liberating!
A wonderful contribution to visual astronomy. Clear, detailed, accurate and user friendly under the stars with its red light background option, multiple rotation positions and easy moving between adjacent maps.
WOW!!!
Thank you for making this available....one more fact proving the people in power have and continue to keep knowledge hidden.
Impressive for the cost.
Uranometria doesn't come close to comparing to this atlas. The only comparable hardcopy star atlas that I know of that compares is "The Great Atlas Of The Sky" at a cost of $250 or more.
almost there ...
The charts are fine but the doco leaves a lot to be desired. I eventually found that the adjacent map tags are hotlinks to the relevant charts. Constellation borders and names - even just abreviations - on the index page would help.
Sweet
Really nice app
Like having Uranometria in your pocket! Amazing! Several suggestions...
Brilliantly designed; a tour de force in bringing the classic star atlas to the iPhone/iPad.
Has nice touches such as a brightness slider & night mode always present discretely at the bottom left of the page. Moving from chart to chart is well designed with buttons on the edges of the screen to go to the adjacent ones. Perhaps the next iteration of the app can add a feature whereby if you swipe at the edge of the screen it will move to the adjacent chart.
Pinch-zooming works well, too.
Another suggestion: Please shift the main index page over by a chart or two. One of the first things I looked for was the Virgo galaxy cluster-- and it's hard to find! You need a chart centered on the space between Virgo and Leo-- and that area of the sky needs to be somewhere other than buried at the absolute right side end of the scrolling index big chart-- and even there it's impossible to tell where to tap!
I would love to see a colors option whereby one could set the colors of different types of DSOs--galaxies in, say, blue; globulars in yellow, star clusters in orange, etc. That would make this even more usable.
In any event, any serious amateur astronomer would do well to download this app--and being free--why not?!

Simple but effective.
Takes the already amazing and free Jose Torres Triatlas mag12 deep sky atlas and makes it paperless. All I need is an iPad and some red plastic to further dim the screen and i can leave the paper charts at home. Orientation flipping for refractor and Newtonian owners and an colour invert red mode to preserve night vision add to the usefulness vs paper charts. Great app and free too!
