ClearNight is a private log of what you actually saw: the target, the gear you used, the place name you recognize, and the sky as you judged it. Four tabs cover the archive. Observe holds nights. Targets holds each object’s history. Gear holds pieces and setups. Sites holds named places. There is no login. Each launch shows a night guide first. Close it to reach Observe.
Start a night
- Open Observe and tap Record tonight.
- Add a target and choose a status. A target and a status are enough to save.
- Attach a place name, a gear setup, sky impressions, a photo, a sketch, a voice note, or typed evidence if you want them. They can wait.
- Save the log. It stays on this iPhone.
Common questions
A page appears before the archive.
That is the night guide. It explains how to record a night, keep gear and places, lay out a prep card, and move a log into History. Tap Close to return to Observe. The launch artwork stays up while the page loads. If the page cannot load, Observe opens on its own. The guide does not contain your logs. ClearNight sends only a random installation identifier, the app and iOS versions, the device model, language, region, and time zone so the page can open.
The app asked for the camera, photos, or microphone.
Those permissions are for evidence you choose to attach. You can deny them in iOS Settings and still write the log. To allow them later, open iOS Settings, find ClearNight, and turn on Camera, Photos, or Microphone.
Does ClearNight know where I am?
No. It does not request location. A site is a name you type, such as a balcony or a park, plus any directions or obstructions you write down.
What does Organize this log do?
It is optional. After you confirm, selected captions and transcripts are sent to OpenRouter and come back as draft lines. Nothing in that draft becomes a saved fact until you confirm the line. Photos and sketches are not uploaded. If organizing fails, write the summary yourself. Your original notes are not replaced.
How do I compare two nights or export?
Open a target with more than one log and use Compare two nights. Export from a log, a target, or a preparation card. JSON export of the whole archive is in the gear-icon Settings screen. Place names stay off a PDF or image unless you include them. There is no separate purchase for these actions.
There is nothing to restore.
This version has no in-app purchases and no subscription, so there is no Restore Purchases button and no Apple ID subscription to manage for ClearNight. If a charge appears from Apple for a different app, check Settings, your name, and Media & Purchases on the device. That charge is not from a ClearNight product.
How do I delete my archive?
Open Settings from the gear icon and choose Delete all data on this device. You can also delete one log, target, setup, place, or evidence item from its screen. Export JSON first if you want a copy. Removing the app deletes its local data as well.
Sample logs
If sample nights are present, they are stored on the device so you can try the archive. Delete them the same way you delete any other log. They are not an account on a server.
