# MCAS Tracker vs SymptomScape

The clearest difference is rating: SymptomScape at 5.0 against MCAS Tracker's 4.5. SymptomScape also leads on update cadence (every 2 days vs every 6 months). MCAS Tracker's advantage is ratings volume (18 vs 1) and device support (4 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. MCAS Tracker sells 16 in-app purchases, starting at $4.95 per month and SymptomScape sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

SymptomScape holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: MCAS Tracker has 18 ratings behind it against 1, so its average is the more settled of the two.

MCAS Tracker ships an update every 6 months, SymptomScape every 2 days. The most recent releases landed on October 8, 2026 and September 28, 2026 respectively.
