# Dri vs Flir Meterlink

The clearest difference is review sentiment: Dri at 63% against Flir Meterlink's 20%. Dri also leads on iOS requirement (13.0 vs 15.1). Flir Meterlink's advantage is rating (4.4 vs 3.6) and update cadence (every 2 months vs every 13 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Flir Meterlink holds the better App Store score, 4.4 against 3.6. That said, the two scores are not equally well evidenced: Flir Meterlink has 63 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 63% of Dri's written reviews are positive against 20% of Flir Meterlink's, so the app with the better star average is not the one people write more warmly about.

Dri ships an update every 13 months, Flir Meterlink every 2 months. The most recent releases landed on October 9, 2026 and October 27, 2026 respectively.
