Verdict
The clearest difference is price: Pill Fortress at Free against Evolvace E3's $4.99. Pill Fortress also leads on update cadence (every 2 weeks vs every 10 months). Evolvace E3's advantage is ads (none vs shown). On in-app purchases, device support and iOS requirement there is nothing between them.
