The Chemical Touch

By Christopher Fennell

Open iTunes to buy and download apps.


Explore the properties of the elements, the standard amino acids, and the nucleobases with The Chemical Touch. A touch sensitive periodic table and chemical information companion, it provides a wealth of information right at your fingertips. Recolor the periodic table by selecting properties other than Atomic Mass to visually investigate periodic trends. Having exhausted the built-in information, the internet button opens the Wikipedia page for the selected element, amino acid, or nucleobase.

A quick guide detailing all the features is available for download at the application website.

What's New in Version 1.7.3

version 1.7.3:

Fixed a display update bug for the reduction potential table.

Included a missing graphic for ionization potential display.

Corrected a multitouch glitch that could cause graphical artifacts.

Customer Reviews

Best Periodic Table app but in need of an update.

I hadn't written a review for this app when I first got it, but here goes.

It's definitely the best-done periodic table app around. It is elegant and simple with a lot of information for every element. The inclusion of Nucleic Acids and Amino Acids has been essential for my different classes (O-Chem, Biochem, Proteomics, Molecular Genetics, among others).

Unfortunately the app is no longer optimized for newer iOS versions. It runs very slowly and still no retina display support. I was able to contact the dev and was lucky enough to get a response. Very busy guy with a lot of research but also very nice. I understand his lack of time to update the app but remain hopeful that he might sometime soon.

I have since installed the Chem Touch widget on my Mac, which continues to work flawlessly. Unfortunately I've moved to another app for my phone as it loads quicker and I usually need the info fast when I'm searching on the phone, but I miss MCT's features dearly.

Thanks to the dev for such a wonderful app and widget.


Press everything!

First thing you should do is play around, exploring all the buttons you can press to see the features of this app.

I've had this quite a while and just stumbled upon the amino acids and nucleic acids sections complete with more information than the $3 iAmino app.

This is a great reference app.

Get your facts straight!

Just because a phone is jail broken doesn't mean every app is hacked! I paid for your app and don't need you making sarcastic remarks about a choice to broaden horizons beyond the visual limitations of a phone. Until you remove this warning I'm putting this on a 'Do Not Pay For' list.

Great app though otherwise!
