# Pi vs Retrogram

The clearest difference is rating: Pi at 5.0 against Retrogram's 4.4. Pi also leads on in-app purchases (none vs 10) and review sentiment (100% vs 66%). Retrogram's advantage is update cadence (every 3 weeks vs every 57 months) and ratings volume (320 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Retrogram sells 10 in-app purchases, starting at $4.99 per month. Pi asks for nothing beyond the download.

Pi holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Retrogram has 320 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 66% of Retrogram's.

Pi ships an update every 57 months, Retrogram every 3 weeks. The most recent releases landed on September 20, 2026 and October 2, 2026 respectively.
