# Pith vs SeeLock

The clearest difference is ads: Pith at none against SeeLock's shown. Pith also leads on iOS requirement (16.0 vs 18.0). SeeLock's advantage is update cadence (weekly vs every 3 weeks). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Pith sells 3 in-app purchases, starting at $4.99 per month and SeeLock sells 6 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Pith ships an update every 3 weeks, SeeLock weekly. The most recent releases landed on September 18, 2026 and September 10, 2026 respectively.
