Most people have no idea where their time actually goes. They have vague feelings — "I was busy all day" — but no data to back it up. LifeOS fixes that. Log every task in seconds, assign a category, and rate how it made you feel. In 7 days you'll see patterns you never noticed — when you do your best work, which tasks drain you, and how much time is silently disappearing to low-value busywork. WHAT YOU CAN DO - Log any task in under 5 seconds - Get AI-powered category suggestions as you type - Rate each task's energy: energized, neutral, or drained - Quick-switch to recent tasks with a single tap - See your net energy score update throughout the day - Discover which categories light you up vs. burn you out FOUR INSIGHTS THAT CHANGE HOW YOU WORK Overall Energy — see your net energy score across all rated tasks so you know at a glance whether your week built you up or wore you down. Time by Category — a visual breakdown of exactly where your hours went. Most people are shocked by what they find. Energy by Category — find out which types of work give you energy and which ones cost it. Protect the ones that matter. Energy by Day — spot the days that drain you and the days you thrive. Patterns emerge faster than you'd expect. BUILT FOR PEOPLE WHO TAKE THEIR TIME SERIOUSLY LifeOS is for founders, knowledge workers, and anyone who suspects they're not spending their time the way they think they are. No scheduling. No planning. No overhead. Just honest data about how you actually spent your day. Log it. Learn from it. Own it.

Verdict
The clearest difference is ads: LifeOS at none against MajestiCal's shown. LifeOS also leads on iOS requirement (15.1 vs 17.5). On price, in-app purchases and device support there is nothing between them.
