# Spyglass vs Memory

The clearest difference is in-app purchases: Memory at none against Spyglass's 4. Memory also leads on ads (none vs shown) and rating (4.9 vs 4.7). Spyglass's advantage is ratings volume (3.9K vs 10) and chart position (#122 vs unranked). On price, review sentiment, update cadence and monetization model there is nothing between them.

Both are free to download. Spyglass sells 4 in-app purchases, starting at $3.99 per month. Memory asks for nothing beyond the download.

Memory holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Spyglass has 3.9K ratings behind it against 10, so its average is the more settled of the two. Written reviews split almost evenly too, at 80% and 80% positive.

Spyglass ships an update every 6 weeks, Memory every 3 months. Both last shipped on September 22, 2026.
