# GLP vs Lumis

The clearest difference is update cadence: GLP at every 3 days against Lumis's fortnightly. GLP also leads on iOS requirement (18.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. GLP sells 2 in-app purchases, starting at $9.99 per month and Lumis sells 1 in-app purchase, starting at $19.99 per year. Whichever you choose, the download price is not the number that matters.

GLP ships an update every 3 days, Lumis fortnightly. The most recent releases landed on November 5, 2026 and October 31, 2026 respectively.
