# ScentMax vs Umbra Insight

The clearest difference is monetization model: Umbra Insight at free against ScentMax's subscription. Umbra Insight also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 91%). ScentMax's advantage is update cadence (every 3 weeks vs every 4 months) and ratings volume (408 vs 5). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ScentMax sells 4 in-app purchases, starting at $0.99 per 7 days and Umbra Insight sells 1 in-app purchase, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Umbra Insight holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ScentMax has 408 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 91% of ScentMax's written reviews are positive against 100% of Umbra Insight's.

ScentMax ships an update every 3 weeks, Umbra Insight every 4 months. Both last shipped on November 5, 2026.
