# Microplastics AI vs Polycheck

The clearest difference is rating: Microplastics AI at 4.7 against Polycheck's 4.1. Microplastics AI also leads on monetization model (freemium vs subscription) and iOS requirement (13.4 vs 16.0). Polycheck's advantage is review sentiment (100% vs 78%). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Microplastics AI sells 1 in-app purchase, starting at $9.99 per month and Polycheck sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Microplastics AI holds the better App Store score, 4.7 against 4.1. Both are backed by a comparable volume of ratings — 9 and 8 respectively. Written reviews complicate that: 78% of Microplastics AI's written reviews are positive against 100% of Polycheck's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 5 days. The most recent releases landed on September 12, 2026 and June 1, 2026 respectively.
