Verdict
The clearest difference is review sentiment: BoulderBook at 81% against Moon Board's 10%. BoulderBook also leads on rating (4.0 vs 1.6) and update cadence (every 2 days vs every 8 days). Moon Board's advantage is monetization model (free vs free with in-app purchases) and ratings volume (184 vs 9). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. BoulderBook sells 5 one-off in-app purchases and Moon Board sells 4 in-app purchases, starting at $100.00 per year. Whichever you choose, the download price is not the number that matters.
BoulderBook holds the better App Store score, 4.0 against 1.6. That said, the two scores are not equally well evidenced: Moon Board has 184 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 81% of BoulderBook's written reviews are positive against 10% of Moon Board's.
BoulderBook ships an update every 2 days, Moon Board every 8 days. The most recent releases landed on September 14, 2026 and September 24, 2026 respectively.
