Nice and clean app. Sadly, the letters get cut off mid-word when you fill a line instead of pushing the entire word onto the next line. It makes longer entries difficult to read on homepage. Maybe this app was meant for symbol-based language like CN, KR, JP but it would be nice to have the option to keep the letters together for romanized language.

Best journal app out of the top ones I've tried. It's simple which I love. There's a paid version but it's just for cosmetics, unlike all the other apps I tried, which were instant deletes based on their subscription model and not actually free at all. My fiancé and I BOTH use this app. It's awesome you can add pictures to each entry. The UI is very clean and simple whereas other apps seem bogged down, menu-heavy, too busy for what journaling *should* be--relaxing and stress relieving! 5 🌟 app

It works really well. I would say that the premium is worth it. You get a decent amount of access for a very small price. The reason it has four stars, is because I feel like for the mood and the weather settings, there should be more options. Because sometimes I don't feel angry or so-so or something like that. Normally it's lethargic, excited, nervous... You get the point. Limited emotions/weather options. Overall, definitely worth it.
