Verdict
The clearest difference is review sentiment: Parametric at 100% against Lirum Device Info's 52%. Parametric also leads on price (Free vs $299.99) and iOS requirement (8.0 vs 17.6). Lirum Device Info's advantage is rating (4.2 vs 4.0) and ratings volume (13 vs 1). On update cadence, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Parametric is free to download; Lirum Device Info costs $299.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Lirum Device Info holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Lirum Device Info has 13 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 52% of Lirum Device Info's written reviews are positive against 100% of Parametric's, so the app with the better star average is not the one people write more warmly about.
Lirum Device Info ships an update every 4 weeks, Parametric every 6 weeks. The most recent releases landed on November 1, 2026 and October 24, 2026 respectively.
