Verdict
The clearest difference is rating: PAT at 3.7 against Mastering Spectroscopy's 3.3. PAT also leads on update cadence (monthly vs every 4 months) and ratings volume (64 vs 6). Mastering Spectroscopy's advantage is review sentiment (40% vs 28%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mastering Spectroscopy sells 1 one-off in-app purchase and PAT sells 3 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
PAT holds the better App Store score, 3.7 against 3.3. That said, the two scores are not equally well evidenced: PAT has 64 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 40% of Mastering Spectroscopy's written reviews are positive against 28% of PAT's, so the app with the better star average is not the one people write more warmly about.
Mastering Spectroscopy ships an update every 4 months, PAT monthly. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
