Verdict

The call

The clearest difference is rating: Book Writer at 3.9 against Gear Design's 1.5. Book Writer also leads on review sentiment (39% vs 0%) and update cadence (every 2 months vs every 12 months). Gear Design's advantage is price ($2.99 vs $3.99) and iOS requirement (9.3 vs 11.0). On ads, in-app purchases and monetization model there is nothing between them.
