HOW SURE ARE WE
Small app: combines its grossing ranks with ratings growth (53 new ratings a month on average since launch). Tested on 418 apps with verified revenue: typically off by about 2.6 times, so the range is wide. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

WHAT THEY COMPLAIN ABOUT · SHARE OF BAD REVIEWS
Lost data, sync, backup58%

7 of the 1 and 2 star reviews.

★★★★★ Ability to export data (or sync to another format) and the ability to place images inline with the text.
★★★★★ I had no intentions of paying $40-$50 to be able to cross platform this app, now I'm out of $10 because I deleted the app since I'm not buying the other platform versions.
★★★★★ I downloaded this, but according to the FAQ, I will need to purchase three separate licenses to be able to synch across my iPhone, Mac laptop, and desktop PC.
Price and subscription42%

5 of the 1 and 2 star reviews.

★★★★★ I attempted to get a refund but Apple refused, therefore I'm going to warn everyone else; this app is advertised as having cross platform capabilities with purchase.
★★★★★ I wish I could have tested this feature before purchasing, because it was a waste of money for me.
★★★★★ But I just wasted my money cause I'm not paying for this app twice.
No customer support25%

3 of the 1 and 2 star reviews.

★★★★★ Also, I looked everywhere for a way to contact you about this before posting a review, but all your contact links dump to a forum.
★★★★★ This does not support multi platform unless you pay for it with windows.
★★★★★ The app can't do it and doesn't support it.
Login and account problems17%

2 of the 1 and 2 star reviews.

★★★★★ There was no option in the free version to sign in and recover my dairy entries.
★★★★★ Thinking it was going to be a free app like the iPhone version with some sort of sign in to sync your paid version together.
Missing features17%

2 of the 1 and 2 star reviews.

★★★★★ I've burnt my fingers too many times on discontinued apps with no way to retrieve all that work.
★★★★★ There was no option in the free version to sign in and recover my dairy entries.
WHAT THEY ASK FOR
  • I'd got everything I need and nothing I don't want. 5★, Oct 3, 2026
  • I'll probably add a daily picture just for that reason, which is fine because it forces me to take a picture or two every day. 5★, Sep 13, 2026
  • I did pay The price to add the weather in that stuff too cause I wanted my location attached to my entries. 5★, Jul 16, 2026
  • I wish everyone just learnt from him a feature rich product that you don't have to pay every month for. 5★, Jun 29, 2026
  • Since I do a lot of traveling I particularly like that I can add the location and photos into my entries. 5★, Apr 13, 2026
  • One feature I would love to see would be the ability to place photos into specific areas of the text. 5★, Apr 13, 2026
  • It's too bad you don't add the ability to add more than one diary. 5★, Mar 21, 2026
  • It would be cool to use ai to sort imported txt, docx, and pretty well any usual file type used for journaling. 4★, Jan 23, 2026

★★★★★Oct 25, 2026
I do love this App

It’s nice to have a place to place your thoughts everyday.

★★★★★Oct 21, 2026
Some good stuff; some bad stuff.

I’m just starting with this app. It was highly recommended initially. It felt pretty good. This morning it stopped my journal writing at 130 words. It’s too early in the morning to try to understand why.

★★★★★Oct 16, 2026
Daily Journal.

Really like the program - switched from using Apple Notes, did not like Apple Journal. My only objection is having images going at the end of the entry instead of inline.

★★★★★Oct 15, 2026
It’s really good!!!

I love it so much it’s really good and yeah

★★★★★Oct 13, 2026
Great app

This app and its sync functionality really helps me develop the discipline of journaling without having to subscribe to a service. Blessings to everyone who worked on this.

★★★★★Oct 12, 2026
Everything I Need

I started journaling with paper and pen, then moved to Day One, which I enjoyed, but the price went up. I found Diarium and I like it better than Day One or any other app I evaluated. It is feature rich at a reasonable cost, works on my iPhone and even has a version for my Windows PC. I would recommend this app to anyone, whether just starting your journaling experience or a seasoned practitioner. I hope you enjoy it as much as I do.
