It feels like I’m writing to the future and reading from the past!

I love this app and use it as a journal. I like how you can send messages to the future, and when you read them you really look back and recall on how you felt then, and compare it to how you feel now. It would be kind of nice if you didn’t have to pay for more cap pieces (you can get some for free by creating daily entries), but when I pay they make me feel like I earned them, and I understand that the creators need to make money, since there is no ads. Definitely recommend.

great! some suggestions...

great way to enter a short log about my day. i live the idea of how i can send a cap to the future as well but it is so expensive ( you have to earn gems by writing daily in order to be able to send one to the future) and i also wish it had more options for how your day was. like all there is is just “great day” “peaceful day” or “ bad day”. maybe they can add a “fun day” or “boring day” or “generally nice day” but i love it for logging my day. and it offers great security- face ID and/or passcode

My new favorite journal

I really like how it restricts you to one entry per day and it costs you something every time you write an entry to the future. Both features make the entries seem more special than they would in a typical journal. One complaint: why do you even show the Chinese New Year cap to users that aren’t in China? It feels like you are teasing us for not being in a special group that you defined.

Developer Response ,

Hi Pyk, glad to hear from you! Showing Chinese New Year cap on unavailable devices is unintended. It is actually a bug and has been fixed in version 2.2.1 (you could update the app on App Store). Thank you so much for your feedback :-)
