# Memory vs Detector Maps

The clearest difference is in-app purchases: Memory at none against Detector Maps's 4. Memory also leads on ads (none vs shown) and rating (4.9 vs 4.7). Detector Maps's advantage is update cadence (every 6 days vs every 3 months) and ratings volume (248 vs 10). On price, review sentiment, device support and iOS requirement there is nothing between them.

Both are free to download. Detector Maps sells 4 in-app purchases, starting at $7.99 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: Detector Maps has 248 ratings behind it against 10, so its average is the more settled of the two. Written reviews point the same way: 80% of Memory's written reviews are positive against 74% of Detector Maps's.

Memory ships an update every 3 months, Detector Maps every 6 days. The most recent releases landed on September 22, 2026 and September 24, 2026 respectively.
