Verdict
The clearest difference is review sentiment: Simeji at 64% against Smart Hello's 10%. Simeji also leads on update cadence (every 2 weeks vs every 2 months) and device support (4 vs 2). Smart Hello's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price and iOS requirement there is nothing between them.
