Verdict
The clearest difference is rating: Munsell Viewer at 3.2 against TerraFlex's 2.4. Munsell Viewer also leads on monetization model (free vs freemium) and iOS requirement (10.0 vs 15.0). TerraFlex's advantage is update cadence (fortnightly vs every 2 months) and review sentiment (12% vs 0%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Munsell Viewer holds the better App Store score, 3.2 against 2.4. That said, the two scores are not equally well evidenced: TerraFlex has 34 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 12% of TerraFlex's written reviews are positive against 0% of Munsell Viewer's, so the app with the better star average is not the one people write more warmly about.
TerraFlex ships an update fortnightly, Munsell Viewer every 2 months. The most recent releases landed on October 21, 2026 and October 20, 2026 respectively.
