Amazing tool for exoplanet observations

Wow, this is an amazing app for exoplanet observations. The tab for transit information tells you specificially when the next transit will occur— this makes planning for an imaging sesson so easy!! The only addition that would be nice would be to have is a column in the exoplanet data listing the magnitude for each object.

Exceptional app, exceptional support

I'm a professional astronomer and I use this app for planning observing runs. I've even queued up observations for a multi-week run using this app, organizing my targets into folders and lists, with color-coding and notes for each target. The interface allows me to check the airmass curves as well as star tracks of each target. The Simbad info for each target is handy but can sometimes be slower than just checking Simbad in my web browser. Finally, I had an issue with the most recent update (I couldn't find my individual target notes), so I emailed support and Cedric got back to me in just an hour or 2! And the app was updated and my problem fixed in short order. Thanks for a great app and exceptional support!
