Verdict
The clearest difference is review sentiment: ChemTracker at 100% against Startpage's 71%. ChemTracker also leads on update cadence (every 10 days vs monthly) and iOS requirement (10.2 vs 15.0). Startpage's advantage is rating (4.8 vs 4.4) and ratings volume (7.3K vs 7). On price, ads, in-app purchases and monetization model 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. Neither carries in-app purchases, so what you see is what you pay.
Startpage holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Startpage has 7.3K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 100% of ChemTracker's written reviews are positive against 71% of Startpage's, so the app with the better star average is not the one people write more warmly about.
ChemTracker ships an update every 10 days, Startpage monthly. The most recent releases landed on October 7, 2026 and October 17, 2026 respectively.
