Nice, simple, yet up to date (not abandoned since iOS 6 like many others) free element reference. – Elementium Review

Nice, simple, yet up to date (not abandoned since iOS 6 like many others),minimalistic, free element reference. The main potential addition that would be nice would be a picture representing each element (like in Theodore gray's elements book). Also the ability to zoom out to see the whole table at once, which (at least on iPhone 6/7 you can't) would be good.
