# Decibel Meter Plus Pro vs LÒMÒGRAPH

The clearest difference is price: LÒMÒGRAPH at Free against Decibel Meter Plus Pro's $2.99. LÒMÒGRAPH also leads on rating (4.5 vs 3.7) and ratings volume (292 vs 81). Decibel Meter Plus Pro's advantage is ads (none vs shown). On review sentiment, update cadence, in-app purchases and device support there is nothing between them.

LÒMÒGRAPH is free to download; Decibel Meter Plus Pro costs $2.99 up front. Decibel Meter Plus Pro sells 1 one-off in-app purchase and LÒMÒGRAPH sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

LÒMÒGRAPH holds the better App Store score, 4.5 against 3.7. Both are backed by a comparable volume of ratings — 81 and 292 respectively. Written reviews complicate that: 53% of Decibel Meter Plus Pro's written reviews are positive against 46% of LÒMÒGRAPH's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 18, 2026 and October 6, 2026 respectively.
