# Plack vs Puro

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.

Both are free to download. Plack sells 2 in-app purchases, starting at $9.99 per month and Puro sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Puro holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Plack has 15 ratings behind it against 2, so its average is the more settled of the two.

Plack ships an update every 5 days, Puro fortnightly. The most recent releases landed on October 2, 2026 and October 3, 2026 respectively.
