Observe the sky like a pro

iObserve is the astronomical app you were waiting for. It is a Mac app (10.9+) that allow you to push the preparation of your observations to a much higher level. It is a 6-years old app, and after more than 4 years as a paid app in the MacAppStore, it is now free. You can read here why it is so. Read below what others have said about it.

What others have said about iObserve (emphasis are mine!):

• I love it (★★★★★) - Version 1.4 (the one currently in the App Store) - Mar 25, 2015: "Cool Airmass plot. Easy access to finder charts from SDSS, DSS, 2MASS, and AAVSO. One click for data from VizieR, SIMBAD, NED and WikiSky. Fancy tools to convert coordinates, time, flux, and distance. All I need for easy peasy observation planing." (a new German user).

• Best in its class (★★★★★) "There is no other app for planing astronomical observations like iObserve. Because of its all-in-one approach, iObserve is also a discovery machine, allowing the user to make connections that were not obvious. And this is perhaps the best thing that can be said about any app. And the author has an amazing roadmap for the app, I can only hope he achieves it. Truly stellar, well done!" (a happy austrian user)

• "Must have for serious astronomers" (★★★★) "Every observer with a mac should have this app, and observers without a mac should buy a mac so they can use this app. It has proven invaluable on multiple observing runs both in the planning phase an while observing." (a happy US user). 

• "Efficient observing " (★★★★) "I witnessed the development of this app from its early beta versions and am pleased that it turned out to be much more stable and clean. I use it everytime I go observing at large observatories [...]." (a canadian "Some Dude") 

• "iObserve" (★★★★) "The Application works extremely well. I needed support and it was very efficient, i had an answer in a few hours." (some enthusiastic italian 'Mr. Fox')

• "A must have app for all serious astronomers" (★★★★) "This little application has now matured very nicely from its origins a few years ago. (...) It will appeal to serious astrophotographers, deep sky enthusiasts and – of course – professionnal astronomers. Yes, you can find the same information if you scout around the web, but iObserve puts it all in once place, and a lot more besides. I couldn't work without it. And the developer, Cédric, provides outstanding support." (a nice follower from Australia)

iObserve Touch


Observe the sky like a pro... now also on iPad!

iObserve Touch on iPad brings almost every feature of iObserve on desktop to the beautiful canvas of the iPad.

Given the limited public, I didn't expect too many reviews... but at least I got one! Here it is (and thanks to its author!):

Grade: A  ★★★★ I do a lot astronomy thru remote (but world class) ground to space observatories, where the sky in real time looks very different than from my local observatory. This app is a Grace of Gott when it comes to figuring out what DSO is best to target for what night at which geolocation at which time to get best use of the observation slots available...
and yes, it also works great for my backyard...
This is a breakthrough astronomy application, it isn't as sexy looking as other AstroApps, but what it does is in terms of being an "easy button" in you getting the astroexploration of your hearts desire done is at a level by itself.

Brown Dwarf Converter


The handy companion for your dark explorations

Brown Dwarf Converter


The handy companion for your dark explorations

BrownDwarf Converter is free iOS app for iPhone and iPad, first developed by Jonathan Gagné, from University of Montréal

The BD Converter is aimed for astrophysics researchers and students in the field of brown dwarfs. It follows tabulated data from BT-SETTL brown dwarfs atmosphere models to convert a given age combined with any of effective temperature, mass or spectral type, to several other quantities, including the aforementioned as well as surface gravity, radius and standard J, H, K, W1, W2, W3 near-infrared magnitudes from the 2MASS and WISE surveys.

Jonathan has been kind enough to entrust his app to me, at onekilopars.ec, for maintenance and future development.  Hence the BD Converter is now entirely part of the onekilopars.ec portfolio, but credits remain to Jonathan for building this very handy app.
