I love this app. I can either go on my laptop or on my phone and just get everything out that I need to, it’s honestly a really great app and I’ve been using it for quite some years now. I definitely recommend to get this app if you love to journal 😊

Love this App!

I love to journal about various segments of my life. Penzu allows me to keep a thoughts/life journal along with an ideas journal, travel journal, foods journal, piano practice journal and others. It’s easy to use, it’s organized, and it looks good.

Journaling like a boss!

I kept a paper journal off and on through the years (mostly off) but I started journaling on Penzu 4 years ago and I’m a regular now! I even upgraded to the Pro version so I could keep multiple journals. I’ve also started transcribing my ancient hand-written journals into Penzu and now I have a life-span record in the cloud. That’s just amazing and I hope one day I can print it all out into a book. I have recommended Penzu to many people over the years.
