Verdict

The call

The clearest difference is price: WorldBounce at Free against Atomus HD's $1.99. WorldBounce also leads on iOS requirement (12.0 vs 15.6). Atomus HD's advantage is rating (4.8 vs 1.3) and update cadence (every 3 months vs every 72 months). On ads, in-app purchases and device support there is nothing between them.
