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.

Restricts access to the words that you write.

I really love just about everything about Time Caps except for how it doesn’t allow you to export your data as text. I’ve actually used this app for years and I’ve spent quite a bit of money to support the developers, but I’m done with waiting for an export feature. The newest update just underscores how little the developers care about giving you access to your data—they now let you edit your old entries, but they charge money for it. So you could move your entries (one by one) to a backup database, but it will not only cost you time but actual money. They’ve also confirmed that they have no intention of adding this through email. Completely ridiculous. I will definitely be checking back to see if they ever add an export as text feature, but until then I’m done with supporting this. Not being able to access text that you wrote in a journal app is insane.

Developer Response ,

Hi Pyk, thanks so much for your feedback. I really appreciate your support all the time.
Here are a few things to address:
First, about "They’ve also confirmed that they have no intention of adding this through email", we've never said this in any email reply. "Exporting data" is a feature on our roadmap but not yet supported. I understand you've waited for so long. But given that the app is still designed, developed and maintained by one person, I had to make choice and implement major features first.
Second, we don't charge money for editing old daily caps. You can spend some Pieces to edit a daily cap after 24 hours but Pieces are not equal to money. You've used Time Caps so long, so I'm sure that you know Pieces are a way that we introduce to encourage users to write daily caps. You can gain Pieces for writing any caps. It's true that you can purchase some Pieces with a few dollars, but it's just one of the ways earning them. In fact, most users did not purchase any pieces.
Moreover, with the update, we introduced several new ways for users to gain Pieces, including weekly/monthly rewards, Piece Reward Program, etc. And meanwhile, we offered ways to help users utilize the Pieces they gained to perform some actions that they could not do in old versions, such as filling a old day, or editing a daily cap after 24 hours.
Last, if this does any help, if you update to the latest version (2.5.4), you can long press the text in a cap and copy them. You don't need to spend Pieces to edit just to copy anymore. I know this is still far away from an ideal "exporting" feature, but I'm working on it.
Thanks again for your support and feedback and love for Time Caps. Have a good day!

It is a great app on diary market, I used one beautiful diary app in the past, but it needs a lot of procedure before I start the writing, so, that app just stayed on my phone few days; but this one is clear and easy, although there are few procedures before I start, but I can finish it quickly wish less finger moves, it is great!

At last, it would be better it can support dark mode
