Periodic Table: Chemistry 2026

I love this version for the Periodic-Table, especially the layout and the graphics. They are very well done. However, there is a major problem with the version for the Apple Watch. Whoever ported over the element data for the Apple Watch version mixed up numbers of neutrons versus protons for at least the first few groups of the periodic table. That would be groups one through at least group four. I haven’t checked them all. I have not recommended this to my students at least for the watch version, since it’s very misleading on those points. Hopefully they will correct this version for the watch. Five stars for the iOS phone version, and 3 stars for the iOS watch version. Hence the average of 4 stars.

This app is everything I want as an undergraduate Chemistry student! There’s so much info within every tab! Fantastic app! One minor concern I have is really just with the boiling points and melting points in the “Properties of some alkanes” table. I believe these values are switched on each alkane such that the melting point is higher than the boiling point (ex. Propane: Boiling Point = -187.6 C, Melting Point = -42.1 C). This appears to be consistent on all of the listed alkanes. A flip of all values would do the trick. Love the app!

Guys this app is amazing and I am constantly recommending it to my friends and anyone going into chemistry. Wether you are in high school or college chemistry this is a useful tool to have to quickly and efficiently use to get the results you desire. I’ve cut my homework time in half by using this and have learnt more about the elements from this app then in lectures. I love how you can get so much for free but you can also upgrade if your doing a degree that will use more advanced chemistry compared to basic organic/nonorganic chemistry.
