Onulchi

Onulchi turns the routine you design into a daily game. "Onulchi" means "today's share" in Korean: you don't have to be perfect, you just have to do today's share. YOUR ROUTINE, YOUR POINTS Pick from suggested tasks across 9 categories, from waking up and eating well to workouts, focus, and time with people who matter. Or create your own. You decide how many points each task is worth. REACH 100 TO CLEAR THE DAY Check off what you did and watch the gauge fill. Reach 100 points and the day is cleared. Add more than 100 points' worth of tasks, and you can clear the day without doing everything. A WEEKLY REWARD YOU CHOOSE Earn 600 points in a week and treat yourself to the reward you picked. It's set at 600, not 700, so one slow day won't cost you the week. LEVELS AND WISHES Write one wish for each level. Clear 30 days in a row to level up. Miss a day and the count starts over, but your level stays. BUILT FOR HARD DAYS - 2ร bonus: tasks you get done on weekends or hard days earn double. - Rest days keep your streak safe. - Must-do tags highlight the tasks that matter most. SEE YOUR WEEK Switch between Today and Week views, fill in days you forgot, and check your stats by week or month. SIMPLE AND PRIVATE - Free, with no ads and no in-app purchases. - Sign in with a one-time email code. No password to remember. - No tracking or analytics. You can delete your account and data in Settings at any time. Questions or ideas: viva.shinjadu@gmail.com

Verdict
The clearest difference is update cadence: Onulchi at every 2 days against Stream Note's every 5 days. Onulchi also leads on iOS requirement (16.4 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
