Both have good reviews, can't go wrong with a free app. :)

Toca Lab
Calling all future scientists!
Welcome to Toca Lab! Explore the colorful and electrifying world of science and meet all 118 of the elements from the periodic table.
Discover elements by experimenting with the lab tools!
- Take your element for a spin in the centrifuge.
- Warm them up in the Bunsen burner.
- Put the element on ice with the cooling agent!
- Add a drop or two of mysterious liquids from the test tubes.
- Change their voltage and make them magnetic with the oscilloscope.
Each element has it's own personality. In Toca Lab, what does Neon sound like? Is Gold heavy or light? Is Nitrogen squishy or hard? Explore, inspect, and study each one and let us know! Can you find all 118?
Got Sorcery! some time ago. Can confirm that it is a good game. It has a very old school 'choose your adventure' book type feel. I ended up getting Sorcery 2 and 3 later as well.
