Verdict

The call

The clearest difference is monetization model: Plack at freemium against Puro's subscription. Plack also leads on update cadence (every 5 days vs fortnightly) and ratings volume (15 vs 2). Puro's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and device support there is nothing between them.
