It is super fun😜but I don’t want to pay to get more time capsules.😢I like how you can write in it like it is a diary😛

I love this app forever❤️❤️😘

Nice idea for an app...


But having to pay for a time capsule EVERY time you want to write a letter?? Sorry, but this is an app that should be a one-time payment and that's it.

Developer Response

Hi, thanks for your feedback. We have released a new version recently. In this new update, we bring Cap Workshop, which makes Caps craftable by Pieces. And Pieces can be regained after posting Daily Caps and Future Caps (also purchasable in Workshop). Therefore, the cost of Caps has changed a little. Looking forward to your updating. Thanks for liking Time Caps:-)
