NULL Memo vs Perfect Lock

NULL Memo is a quick capture tool for notes, lists, and memos—simple, ad-free, and free from endless customization. It focuses on what matters most: writing something down before you forget it. ■ BUILT LIKE A REAL TOOL It avoids feature bloat and smart automation, focusing on fast capture and simple organization. Straightforward, consistent, and reliable. ■ STAYS NEAT IN ANY SCENARIO Use it for anything—notes, ideas, to-do lists, shopping lists, reminders. Whatever you put in, the layout stays structured and readable, so pages never feel messy. ■ ORGANIZE WITH PAGES Create pages to separate your contexts (work, personal, shopping, ideas, etc.). It's a lightweight organization that keeps things tidy without turning into a whole system you have to manage. ■ OFFLINE Your memos are stored locally on your device for instant access and control. No ads. No accounts. Just your notes, where they belong. ■ CALM, RESTRAINED VISUALS The design is intentionally quiet and minimal. It’s made to remove unnecessary distractions and stimulation, and focuses on achieving only a single purpose. Never lose a thought again.

Take your life back. The average person spends years of their remaining life staring at a screen. Perfect Lock shows you that number—and gives you the tools to shrink it. Most screen time apps are easy to ignore. Hit the limit, tap "ignore," extend the timer, and you're right back where you started. Perfect Lock is different. When you hit your limit, the app locks—and it stays locked. No loopholes When you reach your daily limit, that app is blocked for the rest of the day. You can't sneak back in by changing settings, deleting the limit, or turning the feature off. Try to edit it and you'll see "Can't change this today." Limits reset tomorrow—not the moment they get inconvenient. That's discipline that actually works. See the real cost Enter your age and daily usage, and Perfect Lock predicts how many years of your life you'll spend in front of a screen. For most of us, that's the wake-up call we needed. Powerful app limits Pick the apps that drain your time and set a daily cap. Go over it and the app locks automatically—even with Perfect Lock closed. It uses Apple's Screen Time framework to enforce limits reliably in the background. Focus Mode Start a focus session and every app goes dark until the timer ends. Only by finishing the session do you truly reclaim that time—no shortcuts, no quitting early without giving up the reward. Track the time you reclaim - Build a streak for every day you stay under your limits - Watch your total reclaimed time grow - See your last 7 days at a glance Time is the one thing you can't buy back. Perfect Lock helps you stop wasting it. Free and Pro Perfect Lock is free to limit one app. Upgrade to Pro to lock unlimited apps and categories at once. Pro is an auto-renewing subscription.
