These particles can contain harmful chemicals that affect hormones, immunity, and overall health. Trace empowers you to make informed choices about your health by highlighting hidden sources of microplastics in your daily routine and suggesting safer alternatives.

Verdict
The clearest difference is review sentiment: Polycheck at 100% against Trace's 50%. Polycheck also leads on ads (none vs shown). Trace's advantage is monetization model (free with in-app purchases vs subscription) and rating (4.6 vs 4.1). On price, in-app purchases, device support and iOS requirement 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. Polycheck sells 2 in-app purchases, starting at $3.99 per month and Trace sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Trace holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 8 and 28 respectively. Written reviews complicate that: 100% of Polycheck's written reviews are positive against 50% of Trace's, so the app with the better star average is not the one people write more warmly about.
Polycheck ships an update every 5 days, Trace daily. The most recent releases landed on October 1, 2026 and October 6, 2026 respectively.
