Just Nod vs Arc Lock

A private place to say what's on your mind. Just Nod is a calm AI you can talk to about anything: a long day, something you can't stop thinking about, or whatever's on your mind. It listens, replies in a warm, unhurried way, and asks the kind of question that helps you keep going. Everything stays on your iPhone. — NO SIGN-UP No account, no email, no password. Open the app and start typing. Not sure where to begin? Tap a suggestion like "Something's on my mind." — STAYS ON YOUR PHONE Your conversation is saved on your iPhone and answered by AI that runs on your iPhone. It isn't sent to us or anyone else. No ads, no tracking. — WORKS OFFLINE On a plane, in a tunnel, with the Wi-Fi off. Nod doesn't need the internet to reply. — REMEMBERS WHAT MATTERS As you talk, Nod keeps short notes about what's been going on, so you don't have to repeat yourself. You can read every note, forget any of them, or start fresh and clear everything. — OR JUST TALK Tap the mic and say it out loud. Your words appear as text you can check before sending, and your voice is turned into text on your iPhone. — YOUR WAY Choose shorter or longer replies, and whether Nod mostly listens, reflects back, or offers a little perspective. Add a line about yourself and Nod keeps it in mind. — LOCKED WITH FACE ID Turn on Face ID and only you can open it. Not a partner glancing at your phone, not a friend passing it around. — LIGHT AND DARK A warm, simple design that follows your iPhone's appearance, or pick light or dark yourself. — OPEN SOURCE All of Nod's code is public, so anyone can check it works the way we say. WHAT YOU NEED iOS 26 or later. On iPhones with Apple Intelligence, Nod works right away. Other iPhones with at least 6 GB of memory (such as iPhone 13 Pro, iPhone 14 and newer) download Nod's own AI once, about 2–3 GB over Wi-Fi. Just Nod is for everyday conversation and doesn't give professional advice. Made by Speculative Dynamics.

Companies fight for every second of your time to keep you distracted. Taking control of your screen time should be a human right, not something locked behind a paywall. Arc Lock blocks the apps and websites that eat your day, and once a block starts, it stays on. Every feature is free for everyone: no subscription, no account, no ads, no in-app purchases. SCHEDULES Pick apps, app categories and websites, choose the hours and days, and they lock on their own. Overnight windows like 11 PM – 7 AM work too (up to 22 hours). DAILY LIMITS Allow yourself a set time each day, from 5 minutes to 8 hours. See exactly how many minutes are used and left. When the time is used up, those apps lock until the limit resets: at midnight, or at the time you pick (say 4:00 AM, for late nights). A heads-up comes 5 minutes before. TIME-OUTS Not a full block, a pause. After a stretch of use, the apps take a short break, then open again. For example: after 20 minutes of short videos, a 10-minute break. It repeats all day and starts fresh at its reset time. BLOCK NOW Lock distractions right away, from 15 minutes to 12 hours. The Block now button is always one tap away. PLACES Pick one or more places on the map, like the library, your school or the gym, and the apps lock when you arrive. Each place block ends when you leave, or after a set time, whichever you choose, and starts only on the days you pick. Location access is asked for only when you set up a place block, and Arc Lock never sends your location anywhere. STRICT LOCK Every block can have Strict lock, and it's on by default. While a strict block runs: • it can't be stopped, loosened or deleted in Arc Lock • the date and time can't be changed by hand • the block screen has a single button: Close Daily limits and time-outs are locked in until they reset: you can make one stricter once a day, but looser settings only start at its next reset. Want a gentler block? Switch Strict lock off for that block, and you can stop it whenever you like. Switching Strict lock off for the whole app works right away: a block that's running or counting stays strict only until its own reset, or until it ends. DELETION PROTECTION On by default: no app can be deleted from your iPhone, Arc Lock included. Switching it off waits only until your strict blocks reset or end. LOCK-IN Freeze every rule for 1 to 30 days, even between blocks: no loosening, no deleting rules, no deleting apps. Changes you queued before it wait until it ends. WEBSITES BY ADDRESS Type a site like youtube.com and it's blocked in Safari and every other browser, in schedules, daily limits, time-outs and Block now. APPLE'S OWN LOOK Native lists and a compact Liquid Glass tab bar: Home, Blocks and Settings. Names are optional: a block without one is shown by its first app. Five themes (Navy, Graphite, Forest, Plum and Paper), each with a matching app icon. The phone-and-lock mark in the app closes while something is blocked. PRIVATE BY DESIGN Arc Lock works through Apple's Screen Time. Apple keeps your activity on your iPhone; Arc Lock never learns which apps you use and sends nothing anywhere. No account, no analytics, no tracking.
