Stillena is an independent private journal for iPhone. It is not affiliated with Apple, and it is not a skin on Apple Journal.
What is the same category
Both apps help you keep a personal record on iPhone. Both can include writing and other details from a day. Neither requires a Stillena website account, because Stillena has no journal website login.
What Stillena does not claim
Stillena does not replace Apple's free, preinstalled Journal app for every person. Apple Journal can use Apple's broader device family and suggestions. Stillena is smaller on purpose.
This comparison does not copy Apple Journal screens. It also does not describe Stillena features that are not in the current public product.
What Stillena offers instead
Entries stay in local app storage on your iPhone. You can write, speak, attach a photo, and browse your archive. Optional Cloud AI runs only after you consent, and you can turn it off in Preferences.
A subscription is required after onboarding. If you want Apple's free Journal, keep using it. If you want this smaller private practice, get Stillena from the App Store.
