# rr vs 100 Blocks

The clearest difference is ads: 100 Blocks at none against rr's shown. 100 Blocks also leads on update cadence (every 3 weeks vs every 2 months) and iOS requirement (13.0 vs 15.0). rr's advantage is rating (4.1 vs 3.7) and ratings volume (84 vs 3). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. rr sells 8 in-app purchases, starting at $1.99 per month and 100 Blocks sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

rr holds the better App Store score, 4.1 against 3.7. That said, the two scores are not equally well evidenced: rr has 84 ratings behind it against 3, so its average is the more settled of the two.

rr ships an update every 2 months, 100 Blocks every 3 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
