# Lirum Device Info 2 vs Mobile Master

The clearest difference is rating: Mobile Master at 4.5 against Lirum Device Info 2's 4.0. Mobile Master also leads on update cadence (every 6 days vs every 3 weeks) and ratings volume (1.2K vs 285). Lirum Device Info 2's advantage is ads (none vs shown) and device support (7 vs 3). On price, review sentiment, in-app purchases and monetization model 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 Mobile Master sells 3 in-app purchases, starting at $0.49 per month. Whichever you choose, the download price is not the number that matters.

Mobile Master holds the better App Store score, 4.5 against 4.0. Both are backed by a comparable volume of ratings — 285 and 1.2K respectively. Written reviews complicate that: 77% of Lirum Device Info 2's written reviews are positive against 72% of Mobile Master's, so the app with the better star average is not the one people write more warmly about.
