User Reviews

Users praise Moment Diary for its simple, private, and reliable journaling with strong search and long-term data retention, plus convenient backup to a PC. However, recurring syncing issues across devices, occasional data loss after updates or device changes, login/password recovery problems, monetization that gates features behind purchases, and limited data export/data migration frustrate many users. Some stability issues (crashes/freeze) remain. Overall, a strong core journaling app with valuable features, but data-management and maintenance concerns limit trust for some users.

Pros

Simple, minimalist design makes journaling easy and quick, with strong search by keywords, tags, or dates.
Long-standing reliability and data retention across devices; memories stay intact when upgrading or switching devices.
Effective search and organization features (keywords, tags, date lookup) that help find past entries quickly.
Passcode protection keeps journal entries private.
Backup to a PC over Wi‑Fi provides a convenient data safeguard and strong value for money.

Cons

Ongoing syncing/server connection problems across iPhone and iPad, causing data not to sync or disappear.
Risk of data loss after updates or device changes, with difficult restoration and password recovery issues.
Login/password reset problems; losing access to the diary if credentials are forgotten.
Gating features behind purchases (candies/season passes) and subscription models can hinder basic journaling.
Limited data export/migration options and occasional stability issues (crashes or freezes).

I love Moment Diary, but I am unable to use all of its features. I cannot create an ID, don’t know how to get and use stickers, cannot back up. Can anyone help? Thank you!

I’ve been using this app since 2011. I can’t believe it’s still this awesome :)

I’ve been using this app for years on both my iphone & ipad and now it will no longer sync!!! It says it can no longer connect to the server & try again in a little while. It’s been giving that message for days.
