Verdict

The call

The clearest difference is price: Atomus at Free against Silk Legacy's $2.99. Atomus also leads on rating (4.8 vs 3.8) and update cadence (every 2 months vs every 15 months). Silk Legacy's advantage is ads (none vs shown) and iOS requirement (7.0 vs 15.6). On review sentiment, in-app purchases and device support there is nothing between them.
