"Day One not only nails the experience of a local blog (or journal as they call it) in an app, but also has (built) a great technical infrastructure — it works fantastic (when) offline and has a fully encrypted sync mechanism, so the data that’s in the cloud is secured in a way that even someone with access to their database couldn’t decode your entries, it’s only decrypted on your local device. Combining encryption and sync in a truly secure way is tricky, but they’ve done it."
