Verdict
The clearest difference is review sentiment: EXFO Power Checker at 100% against Nrby's 0%. EXFO Power Checker also leads on iOS requirement (8.0 vs 13.0).

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. Neither carries in-app purchases, so what you see is what you pay.
Nrby holds the better App Store score, 2.8 against 1.0. That said, the two scores are not equally well evidenced: Nrby has 20 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Nrby's written reviews are positive against 100% of EXFO Power Checker's, so the app with the better star average is not the one people write more warmly about.
Nrby ships an update every 5 weeks, EXFO Power Checker every 8 months. The most recent releases landed on October 10, 2026 and October 20, 2026 respectively.
