# Pi vs Loop Chain

The clearest difference is in-app purchases: Pi at none against Loop Chain's 5. Pi also leads on ads (none vs shown) and rating (5.0 vs 4.6). Loop Chain's advantage is update cadence (every 17 months vs every 57 months) and ratings volume (22 vs 1). On price and device support there is nothing between them.

Both are free to download. Loop Chain sells 5 one-off in-app purchases. Pi asks for nothing beyond the download.

Pi holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Loop Chain has 22 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Pi's written reviews are positive against 81% of Loop Chain's.

Pi ships an update every 57 months, Loop Chain every 17 months. The most recent releases landed on October 7, 2026 and October 8, 2026 respectively.
