It's really very gud.I never used this types of apps before but I installed many apps similar to dairies and later on found no interest.but this app was amazing 🤩 their one problem in it which I am feeling uncomfortable it don't have a option to change the time format actually I don't use 24 hours format i would like to keep 12 hours format.if this thing Is changed it would be still better 👍🏻 Thank you. The changes were immediately made after some time which is really good 🤗

Zendiary is a fairly decent journal app. It has a bunch of functionality. The features include password protection. This one also tracks your mood. Each entry has a mood that you choose. There are dozens of them to choose from. It also has really peaceful designs which just melt your mood tbh. Although this app should contain a option to change dates so that it can be put as a memory. Overall, I love Zendiary and its thr perfect app to express your feelings.
