Verdict
The clearest difference is price: Pill Fortress at Free against Chaos Theory Exploding Pro's $0.29. Pill Fortress also leads on update cadence (every 2 weeks vs every 38 months). Chaos Theory Exploding Pro's advantage is in-app purchases (none vs 10) and ads (none vs shown). On device support there is nothing between them.
