I've been wondering what kinds of science apps I should get (I hope this topic has not already been dealt with here).
I could easily do a Google search for them, which I will, but I'd also like to get some recommendations from the ever-reliable RDFRS community.
I'm looking for apps from all the sciences: biology, chemistry, physics and related subjects.
Any platform is OK, too: android, i-phone, or whatever.
I'd like both free and pay-to-use app recommendations. If you could also briefly say what the benefits of the app is, that would be great. Thank you.
