How we grade them
| 3.6GPADay OneExcellent | 3.2GPAGrid DiaryVery good | |
|---|---|---|
| Value for money | BSilver is $49.99 a year, which is about typical for a journaling app, and it adds sync on unlimited devices, 30 photos or videos per entry, audio and drawings. But there's no monthly plan, and the AI tools need Gold at $74.99 a year. | BMembership is $4.99 a month or $29.99 a year on the US App Store, about typical for a journaling app. One subscription covers all your devices and adds sync, the passcode lock and more colour themes. Oddly, Grid Diary's own site quotes less: $2.99 monthly and $22.99 annual. |
| Free plan and trial | BBasic gives you unlimited text entries and journals, prompts, templates and end-to-end encryption for nothing. But it works from 1 device with 1 photo per entry, so there's no sync. A free 1-month trial of a paid plan starts inside the app. | BMany of the features are free, though the listing can't say exactly where the line falls. What's clearly held back is sync between devices, the passcode lock and extra themes. So free means one device and an unlocked diary. The US App Store gives 3 days free on monthly and 1 week on annual. |
| Features | AMarkdown text with photos, video, audio, drawings and scanned PDFs. Browse by calendar, by map or by On This Day, which resurfaces entries from past years. Add a daily prompt, templates, streaks and an app lock, and on Gold an AI Daily Chat and entry summaries. | BA grid of prompted boxes per entry, from a built-in library or your own. Daily, weekly, monthly and yearly entries, templates for gratitude, goals and planning, a Markdown editor, several journals, tags and export to PDF, Markdown and JPG. Solid. Photos are the only attachments named, and the lock is for members. |
| Ease of use | A4.8 from about 118,400 App Store ratings. A daily prompt, a prompt gallery and templates are on every plan, so you've always got somewhere to start. Reminders and streaks are there to bring you back. | A4.6 from 963 App Store ratings. Answering one short question per box is easier than facing an empty page, and templates set the grid up for you. One thing to check: the App Store version needs iOS 26, iPadOS 26 or macOS 26 or later. |
| Platforms and integrations | AiPhone, iPad, Apple Watch, Android, Mac, Windows, the web and a browser extension. Silver adds Strava, Zapier and IFTTT integrations. Just remember that journaling from more than one device is a paid feature. | BiPhone, iPad, Mac and Android. There's no Windows app, and no web version is listed, so on a PC you're out of luck. The only connection on record is Apple Health, and sync between devices is members only. |
| Best for | one journal on every device you own | answering prompts in place of a blank page |
