Ember

Ember is a habit and challenge tracker for people who show up. Create your own challenges (gym, reading, running, sober days, side projects), check in once a day and watch the chain grow. Miss a day and it resets. That's the point. MEET EMBER, YOUR AI DISCIPLINE COACH Ember learns what pulls you off track and when you usually slip. She builds your plan and reminds you before the moment you'd usually give up. Every day she leaves you a personal message on Home, and you can ask her anything. SIX LIFE AREAS, ONE HONEST PICTURE Every challenge belongs to one of six areas: Body, Mind, Create, Focus, Connection, Joy. Ember suggests the area as you type the name. Your Stats open with Balance, a six-axis chart of where your effort went in the last 7, 14, 30, 90 or 365 days, compared with the period before. When one area goes quiet, Ember names it and offers a five-minute challenge to bring it back. A PLAN THAT FITS HOW YOU FEEL Every morning Ember asks one question: how big is your flame today? Pick one of five flames, right from your lock screen on iOS 17.2 and later, and she shapes today's plan around it. On a rough day she keeps the essentials and moves the rest. On a great day she lets you go further. Tell her when you wake up and she times the morning around you. FREE TO START No subscription needed: • Keep one challenge going and check in on it every day • The morning mood check-in and a daily plan from Ember • Chat with Ember: 5 messages a day • Your streak, your check-in history, Balance and your 90-day heatmap • Full stats on your discipline • Coins for every check-in, for steps and for focus time • The community feed and Explore EMBER PRO • 2× Sparks on everything you earn: every check-in, run, walk and focus session pays double • Unlimited challenges: check in on every one of them, not just one • More time with Ember: up to 25 messages a day • AI insights and deep stats: an honest weekly read on how your week actually went. No cheerleading, just your data • Smart nudges, so a streak doesn't break because you forgot • Public challenges, events and planning • Badges and the full Explore catalogue FOCUS TIMER Start a focus session on any time-based challenge. It runs full screen with nothing else on it, and you get a notification when the time is up, so nothing gets lost in the background. READS YOUR ACTIVITY, DOESN'T ASK YOU TO RETYPE IT Steps and workouts come straight from Apple Health, and step challenges check in on their own, even with the app closed. Strava and more connectors are supported. Nothing to log by hand. 3-DAY FREE TRIAL Every new Pro subscription starts with a 3-day free trial that gives you full Pro access.

Verdict
The clearest difference is ads: The Core Code at none against Ember's shown. Ember's advantage is update cadence (every 4 days vs every 3 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
