# My Allergy Score vs Trace

The clearest difference is in-app purchases: My Allergy Score at none against Trace's 5. My Allergy Score also leads on ads (none vs shown) and rating (5.0 vs 4.6). Trace's advantage is update cadence (daily vs monthly) and ratings volume (28 vs 2). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Trace sells 5 in-app purchases, starting at $4.99 per 7 days. My Allergy Score asks for nothing beyond the download.

My Allergy Score holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Trace has 28 ratings behind it against 2, so its average is the more settled of the two.
