Measuring is free. Whittle counts a week of your own screen time on the apps you choose, then gives you one number: your daily average. Whittle Pro lowers that number by 8% a week, over twelve weeks by default. Once today's minutes are used, a pause appears in front of the apps you chose. One tap on Open anyway lifts it. A pause, not a lock. HOW IT WORKS 1. Pick the apps that take your time. 2. Whittle measures for a week. Nothing changes while it counts. 3. After a week you get one number, say 82 minutes a day. 4. With Whittle Pro, each week's daily target is 8% lower: 82, then 75, then 69. Eighty-two minutes a day becomes about thirty after twelve weeks. A few minutes at a time, small enough not to feel. FREE Measuring your week, and your number. Today's minutes, and your history. No account, no payment. WHITTLE PRO A daily target that falls 8% a week. The pace and the length of the program are yours to change. Once today's minutes are used, a pause in front of the apps you chose. Open anyway lifts it with one tap. It may ask again later that day. On Sunday, next week's target. A widget that counts down what is left today. If a week felt steep, hold the same target one more week. Don't want to wait a week? Start today from a limit you choose. ABOUT THE PAUSE While a pause is up, iOS may hold back notifications from those apps, so messaging apps like WhatsApp are best left off the list. You can turn the pause off in Whittle's settings; your minutes are still counted. WHAT IT WON'T DO No red. No streaks to lose. No badges, no confetti, no comparison with anyone else. WHAT YOU GET BACK 82 minutes a day is 20 days a year. Twelve weeks later it's about seven. PRIVATE BY DEFAULT No account. No login. No analytics. Your minutes stay on the phone that measured them, unless you send a report yourself with Share diagnostics. The subscription is the one thing that talks to the outside, and it never carries a minute with it. NOTIFICATIONS A note when your number is ready. Then one each Sunday: your week, and with Whittle Pro, next week's target. No sound. SUBSCRIPTION Whittle Pro is an auto-renewable subscription, yearly or monthly. If you are eligible, the first 7 days are free; the price for your country is shown before you confirm. It renews automatically unless cancelled at least 24 hours before the end of the current period. Cancel anytime in Settings.

Verdict
The clearest difference is in-app purchases: Whittle at none against ReplaceMate's 1. Whittle also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 5 weeks). ReplaceMate's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price there is nothing between them.
