Read full descriptionHide full description
One day a page. One intention, a few moments, then seal it. sDiary is a slow, intentional journal. You write a single line for what the day is about, capture a handful of moments as text, photos, or voice, and then seal the page. Once a day is sealed it goes into your book: the long arc of every page you've written. No streaks. No engagement loops. No coach. No social. The day is yours, and so is the book. The flow. Morning. Set an intention. One sentence. Through the day. Add moments. Text, photo, or voice. Evening. Reflect. Seal the day. The page closes; tomorrow is a fresh one. Threads (Pro). The phrases that keep coming back across your sealed days, surfaced automatically. All computation happens on your device. No cloud, no AI provider. Trusted Reader (with Sync). Invite exactly one person you trust to read your sealed days. They see what you chose to share, when you chose to share it. Revoke any time. Year-Review. Every December 31, sDiary auto-opens a retrospective of the year: the intentions, the recurring threads, the sealed-day count. Free, Pro, and Sync. The base app is free, forever. Pro is a one-time unlock that opens Threads, voice moments, unlimited photos per day, full-history search, and Year-Reviews. Sapplify Sync is free with a Sapplify account and covers multi-device sync and the Trusted Reader feature, across every Sapplify app. Local-first, by default. Your days live in a SQLite database on your phone. Nothing leaves your device unless you turn on Sapplify Sync, and even then, only your own data, to your own account.

Verdict
The clearest difference is device support: sDiary at 3 against MyMoodLab's 1. sDiary also leads on iOS requirement (15.0 vs 17.6). On price, update cadence, ads and in-app purchases there is nothing between them.
