# StayBack vs Know & Act

The clearest difference is in-app purchases: StayBack at none against Know & Act's 1. StayBack also leads on ads (none vs shown). Know & Act's advantage is update cadence (every 2 days vs every 2 weeks) and iOS requirement (13.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. Know & Act sells 1 one-off in-app purchase. StayBack asks for nothing beyond the download.

StayBack ships an update every 2 weeks, Know & Act every 2 days. The most recent releases landed on October 31, 2026 and November 5, 2026 respectively.
