Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Lanthier sells 2 in-app purchases, starting at $19.49 per year. MIR Spiro asks for nothing beyond the download.
MIR Spiro holds the better App Store score, 4.5 against 3.8. Both are backed by a comparable volume of ratings — 5 and 2 respectively. Written reviews complicate that: 62% of Lanthier's written reviews are positive against 17% of MIR Spiro'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 September 28, 2026 and September 19, 2026 respectively.
