Simple and efficient
This app is exactly as described. I especially like the hashtag feature. I’m using it to keep a simple, clean diary, to record observations and thoughts easily. I checked out several diary apps and found this one is the best for me.

This app is perfect.
I wanted to start journalling to get my thoughts out of my head to set them aside. I'm a planner, so I started researching. I quickly got sucked into a vortex comparing subscription plans, lifetime costs and features. I was stressing out trying to pick a platform to help me not stress out. This app is perfect. It's intuitive and elegant in its simplicity. I open, I write. No intrusions (ads) and no distractions ("great streak!" "Look at this map!" "What's your mood?!"). It just lets me write.

I think this one is a keeper.
I really like it. I dont feel overwhelmed or even sad when I use it. Nothing I need to accomplish. No book to fill up. No charts. No moods.
Weird. But each app I try to use (or even physical notes) its too much to handle. This is easy. I really like the # too.
I think this one is a keeper. I like it a lot

Nails the core functionality
This is probably the only journal app I would ever care to use. As of writing it does not require you to lock in to its system. Your data is yours to take with you via a JSON export. The idea of open and write is exactly what a journal should be.

Maker Origin Story

A while ago, Shao (@randomor) was on paternity leave and wanted to record moments of his baby and all the random/crazy ideas he had.
He wanted to find a journaling app that's as fast and simple as chatting.
To his surprise, he couldn't find any.
So he created ZenJournal.
