Verdict
The clearest difference is monetization model: Symptom Tracker゜ at freemium against SickPredict™'s subscription. Symptom Tracker゜ also leads on rating (4.6 vs 4.1) and ratings volume (973 vs 32). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. SickPredict™ sells 2 in-app purchases, starting at $3.99 per month and Symptom Tracker゜ sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Symptom Tracker゜ holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: Symptom Tracker゜ has 973 ratings behind it against 32, so its average is the more settled of the two. Written reviews point the same way: 73% of SickPredict™'s written reviews are positive against 90% of Symptom Tracker゜'s.
SickPredict™ ships an update every 2 months, Symptom Tracker゜ every 6 weeks. Both last shipped on November 3, 2026.
