Variable Star app for Android now available

Hi! I just wanted to let you know that Variable Stars for Android is now available in the Play Store -- thanks to all my beta testers for helping me work out some of the issues in the beta version!

Variable Stars is a simple resource to provide a clean interface to access basic information about variable stars that can aid in planning observing sessions or just for general knowledge. 

Features include: 
    • View basic info for any star in the database, including current altitude, location, variable type, spectral type, etc.
    • 9 pre-made lists of variable stars based off of AAVSO's observing sections
    • What's Up: the 200 stars most suited for observing currently at your location (or at the time, date, and location you specify)
    • Search: search the database of over 300,000 variable stars by name, magnitude, constellation, or period

Download the app here

Thanks for reading and clear skies!

Unknown source

I don't know what Tutuapp is, but the only real place to download the app is direct from the Google Play store - anything else is isn't a legit version and is probably spam or has a virus or something. Also, the note above is a direct copy of one of the app's reviews so I'm thinking this is spam.... :/

Hello Michelle,


This is a great tool – thank you!! Any plans for an apple version?


Best wishes – clear skies,



Open source? F-droid?

Thanks for making this! Would you consider making it open source and releasing it through for those of us who don't like google?

It works

For stars with well-know predictability, it would be useful for the app to list expected observed magnitude for any date.  Do database exist generally reflecting future expected apparent brightness?  I'm brand new to AAVSO.  Thank you, BO
