# Bio vs GLP

The clearest difference is update cadence: GLP at fortnightly against Bio's every 2 months. GLP also leads on iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Bio sells 3 in-app purchases, starting at $1.99 per 7 days and GLP sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Bio ships an update every 2 months, GLP fortnightly. The most recent releases landed on October 13, 2026 and October 24, 2026 respectively.
