Pick a habit from a library of 36 across fitness, nutrition, mind, sleep, learning, productivity, spiritual, and relationships. Or create your own. Set a duration from 7 to 365 days (30 is the default). Choose tough mode (strict, with a Be Honest recovery if you miss a day) or soft mode (forgiving, no penalty).

Verdict
The clearest difference is in-app purchases: 5plus math at none against 30 Day Challenge's 2. 30 Day Challenge's advantage is update cadence (every 2 months vs every 6 months). On price, ads, device support and iOS requirement there is nothing between them.
