Work plans, personal errands, and the thoughts that pop up in between. Your whole day, in a notebook that is yours alone. HW Journal is a notebook app for people who love to write by hand. Write and expand ideas on iPad; check tomorrow and wrap up the day on iPhone. Two devices, one notebook. ■ What you didn't finish comes back to you Circle something, or underline it, with the Carry-over Pen, and it moves to the top of tomorrow's page at its original size. It stays every day until you erase it, so even if you forget you wrote it down, it finds you. Each morning, Today's Summary gathers carried-over items, events, and to-dos in one place. ■ A big A3 page to write freely (new in 2.0) The memo area is one full A3 sheet. In portrait you see the A4 half; slide right to reach the rest. Whatever the device or orientation, what you wrote looks the same. ■ Photos and stickers Place photos, rotate them, resize them. Lift the subject out of a photo and stick it on the page as a sticker. ■ Sticky notes Small handwritten notes you can put anywhere on the screen. ■ Daily records beside the date Show medication, blood pressure, weight, steps, and trash-day reminders next to the date. Turn off whatever you don't use, one by one. Health records are stored only on your device, never in iCloud. Connecting to Health is optional and off by default. ■ A small touch for other pens If you use a pen other than Apple Pencil, double-tap the page with a finger to switch between pen and eraser (turn it on in Settings). You can also trigger the switch from the Shortcuts app. ■ And more - Day view, week view, and month calendar, linked with Apple Calendar and Reminders - Five-year diary and Day Diary, protected by Face ID or passcode - Extra pages with blank, ruled, or grid backgrounds, plus PDF markup - Holiday colors, and Japanese rokuyo, holiday names, and weather - Touch mode lets you use the app with just your finger - Most display items can be switched on or off in Settings - You can go back to the previous layout (1.x): Settings > Display & Layout > Screen Layout ■ Pricing The app itself is free. The Supporters Pack (one-time purchase) unlocks more pages, backgrounds, search, passcode lock, and more. Tips are also available. ■ Note If you use both iPad and iPhone, update both to 2.0 before using.

HW Journal's advantage is ads (none vs shown) and update cadence (every 4 days vs every 19 months). On price and device support there is nothing between them.
