App is unusable for me

I like Penzu, but the app has been unusable for me. I usually switch between writing entries on my laptop and my iPhone, and up till last year I didn’t encounter issues with that setup (with just a few occasional glitches that support could help out with). But for some reason I can’t sync Penzu on my phone anymore. Photos I upload from my phone into entries don’t save. The app is honestly infuriating. I’ve contacted support several times but I don’t even think they understand the issue. I have so many entries on Penzu, but not sure if I should stick with it any longer.

Easy and focused

I love there is a desktop version and app so I can write in both places. Also that there is a functional journalling that doesn’t cost. The setup is simplified and streamlined layout, helping to not overwhelm my head.

Please add a dark mode

Love this app, been using it for years and my only issue is that even with my brightness on the lowest setting with night shift on to tint the blue light into warm: opening the app at night in a dark room feels like setting off the white hot intensity of a thousand suns straight into my corneas 😵‍💫

Other than that love the application and can’t find any other qualms

Really upset with the sync issue

I’ve normally been loving this app. It’s free, you can access it on your phone app as well as the web, and it syncs.

However!! I don’t know what happened. I’ve mostly been using the web version, but I was in bed, so I wanted to add something I thought of using the phone app. The phone app had not been syncing. Today, I finally remember while on my computer, and I noticed it synced the web version to whatever was on the phone app a missing MONTHS of an entry I’ve been working as a recap to myself to read on my birthday. Additionally, I am pregnant with my first, so it had a lot of updates about all things baby, and I am just really upset that I lost all of those updates to myself.

If anyone at all still checks the comments and updates the app, PLEASE reach out, so I can recover the rest of the entry.

Pro isn’t worth it

When you subscribe to pro the only feature you get is changing the background colour. It’s utterly useless. You still can’t do full screen editing, you don’t get version history (which is terrible because your entries disappear all the time), and half the buttons in the UI ask you for more money. It’s a greedy little app that basically takes your money and gives you nothing.
