# U vs 43Chat

The clearest difference is in-app purchases: 43Chat at none against U's 3. 43Chat also leads on ads (none vs shown). U's advantage is update cadence (weekly vs every 3 weeks) and iOS requirement (13.0 vs 15.1). On price and device support there is nothing between them.

Both are free to download. U sells 3 in-app purchases, starting at $1.99 per month. 43Chat asks for nothing beyond the download.

U ships an update weekly, 43Chat every 3 weeks. The most recent releases landed on October 25, 2026 and October 31, 2026 respectively.
