# Locked In vs 8

The clearest difference is ads: Locked In at none against 8's shown. 8's advantage is update cadence (every 2 days vs every 2 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Locked In sells 1 one-off in-app purchase and 8 sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Locked In ships an update every 2 weeks, 8 every 2 days. The most recent releases landed on October 19, 2026 and October 6, 2026 respectively.
