Verdict
The clearest difference is price: MemPie AI at Free against BlankStudy's $1.99. MemPie AI also leads on update cadence (every 5 days vs fortnightly) and iOS requirement (12.0 vs 17.0). BlankStudy's advantage is in-app purchases (none vs 2) and ads (none vs shown). On device support there is nothing between them.
