Recent User Sentiment
“Recent user voice shows a mixed sentiment. Users appreciate nostalgia & 'on this day' feature and versatility & media integration, but report critical stability & performance and aggressive monetization.”
What Users Love
I love looking back at This Day over the years.
“On this Day” is a key feature that makes me want to write and keeps me coming back.
By far the best, most versatile journal app I’ve found.
I love the way the app lays out your previous entries... scrapbook vibe.
Pain Points
The app will not open, says waiting... Now I’ve lost all those entries.
There is a huge lag on every action.
Impossible to use the free version because it prompts to buy the paid version literally every 15 to 20 seconds.
