Verdict

The call

The clearest difference is price: MemoCal mini at $1.99 against Lirum Device Info's $299.99. MemoCal mini also leads on review sentiment (66% vs 52%) and ratings volume (72 vs 13). Lirum Device Info's advantage is update cadence (every 4 weeks vs every 4 months) and rating (4.2 vs 4.0). On ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Lirum Device Info holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: MemoCal mini has 72 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 66% of MemoCal mini's written reviews are positive against 52% of Lirum Device Info's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

MemoCal mini ships an update every 4 months, Lirum Device Info every 4 weeks. Both last shipped on October 26, 2026.
