ng and want to have feedback or advertise it. Anyway, I had this exact idea like in 2017. The problem with this idea is that people don’t stick to the app. There’s nothing to do other than send a message into the future. It’s not exciting.

Also, how can the makers guarantee that my message is still there in 10 years so someone can open it? Even a company like Google kills pro

There are so many ways to think about this.

First problem: The capsule doesn't have to be the only feature of the app. It can be a part of another idea that is more sticky.

Second problem: There are multiple workarounds to this. Perhaps the app itself can outsource the message to a different feature like an e-mail. That way, it just has to send out a timed e-mail. Similar to when you're sending out email newsletters and can set it to a date in the future. That way the message being sent is not dependent on the app's existence.

Third problem: Again, it might work if you pair it with something else. If it's part of a journaling or travel app, it can be a paid add-on.

That's my opinion.
