2. Brain It On! Physics Puzzles by Orbital Nine
This app presents a challenging and fun collection of physics puzzles. The games might seem deceptively easy initially, but each game is timed and scored, making it significantly harder. The goal is to draw a particularly shaped object, or “machine,” in order to complete each task. Consider each task as a possible element of a Rube Goldberg machine; for example, what can be drawn, and in what shape, to tip over that cup?

3. Peak by Peaklabs
This app includes more than thirty games across a variety of categories, with one new game added per month. This app is similar to Mind Games Pro (except that this app is free to download!) in that it also focuses on specific areas like improving memory or problem solving. Peak offers the ability to personalize your experience and set goals, in addition to providing scores and producing a critical evaluation on your performance.

4. Curiosity by Curiosity.com
This app, unlike the others, focuses on improving your knowledge of particular subjects by presenting you with daily information, in the form of interesting facts and visual content. The facts tend to be historical, geographical, or technological, and you can consume the content in the form of a video or an infographic. The goal of the app is to remind us that learning new information is exciting; think of it as a library of knowledge that has been condensed so that you can learn more in a shorter amount of time. What could be better than that?
