# ThinkSpace vs BigPaper

The clearest difference is review sentiment: ThinkSpace at 54% against BigPaper's 27%. ThinkSpace also leads on rating (4.3 vs 4.0) and ratings volume (273 vs 17). BigPaper's advantage is update cadence (every 5 days vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ThinkSpace sells 2 in-app purchases, starting at $2.99 per month and BigPaper sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ThinkSpace holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: ThinkSpace has 273 ratings behind it against 17, so its average is the more settled of the two. Written reviews point the same way: 54% of ThinkSpace's written reviews are positive against 27% of BigPaper's.

ThinkSpace ships an update monthly, BigPaper every 5 days. The most recent releases landed on October 10, 2026 and September 29, 2026 respectively.
