Verdict

The call

The clearest difference is rating: GlowWords at 5.0 against ReadEra's 4.2. GlowWords also leads on review sentiment (100% vs 60%) and update cadence (every 3 weeks vs every 2 months). ReadEra's advantage is in-app purchases (none vs 5) and ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
