# CPAP Tracker vs AllergySentinel

The clearest difference is rating: AllergySentinel at 5.0 against CPAP Tracker's 3.5. AllergySentinel also leads on ads (none vs shown). CPAP Tracker's advantage is ratings volume (8 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. CPAP Tracker sells 1 one-off in-app purchase and AllergySentinel sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

AllergySentinel holds the better App Store score, 5.0 against 3.5. That said, the two scores are not equally well evidenced: CPAP Tracker has 8 ratings behind it against 1, so its average is the more settled of the two.
