# U vs HabitDot

The clearest difference is in-app purchases: U at none against HabitDot's 1. U also leads on ads (none vs shown). HabitDot's advantage is update cadence (every 3 days vs monthly) and iOS requirement (12.0 vs 14.1). On price and device support there is nothing between them.

Both are free to download. HabitDot sells 1 in-app purchase, starting at $1.99 per month. U asks for nothing beyond the download.

U ships an update monthly, HabitDot every 3 days. Both last shipped on September 9, 2026.
