# Lirum Device Info 2 vs CPU Detector

The clearest difference is rating: CPU Detector at 4.6 against Lirum Device Info 2's 4.0. CPU Detector also leads on iOS requirement (11.0 vs 15.2). Lirum Device Info 2's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 2 months). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Both are free to download. Lirum Device Info 2 sells 3 in-app purchases, starting at $0.99 per month and CPU Detector sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

CPU Detector holds the better App Store score, 4.6 against 4.0. Both are backed by a comparable volume of ratings — 290 and 427 respectively. Written reviews complicate that: 77% of Lirum Device Info 2's written reviews are positive against 76% of CPU Detector's, so the app with the better star average is not the one people write more warmly about.

Lirum Device Info 2 ships an update every 3 weeks, CPU Detector every 2 months. The most recent releases landed on November 6, 2026 and November 11, 2026 respectively.
