SelfMastery 30

SelfMastery gives you one meaningful goal and thirty days to move toward it. Not another habit tracker asking what you want to track. SelfMastery asks what you want to change - then works out what you should do today. CHOOSE ONE GOAL Study more consistently. Become more active. Find a better job. Take control of your money. Spend real time with your family. Read again. Finish the thing you keep restarting. Or describe something in your own words. GET A PLAN THAT FITS YOUR ACTUAL LIFE Answer a few questions - how much time you genuinely have, what usually gets in your way, when you're most likely to act - and SelfMastery builds thirty days of small, specific actions. Week one is deliberately easy. The plan grows only once showing up has stopped being a decision. KNOW WHAT TO DO TODAY Open the app and see today's actions. Nothing else competes for attention. Tick them off as you go. MINIMUM DAY Some days fall apart. Instead of skipping, switch to a Minimum Day: the same commitment at its smallest size. A thirty-minute walk becomes five minutes. Reduce the requirement, not the commitment. REFLECT IN SECONDS One tap to say how the day felt. A note if you want one. Nothing longer. ADJUST EVERY WEEK Every seven days you look back for two minutes. If the week was hard, next week gets lighter - SelfMastery never responds to a difficult week by asking for more. Days you've already completed are never rewritten, and every change to your plan comes with the reason for it. SEE WHAT YOU ACTUALLY DID Your calendar, your consistency, and observations drawn from your own record - never invented. On Day 30, what changed, in your words and in real numbers. BUILT TO BE CALM No streak warnings. No guilt. No badges or confetti. A missed day isn't a failure, and the app never tells you it is. SelfMastery is for anyone with something they've been meaning to change.

Verdict
The clearest difference is in-app purchases: SelfMastery 30 at none against IIVA's 1. SelfMastery 30 also leads on update cadence (every 9 days vs every 3 weeks). IIVA's advantage is device support (4 vs 1) and iOS requirement (15.0 vs 18.0). On price and ads there is nothing between them.
