Altair: Planetary Log
Anonymous logs adrift in space
Free · Designed for iPad. Not verified for macOS.
Leave a line and it drifts into space. A log no one has read stays veiled — the first to open it becomes its first observer. A four-character code is all you are.
Altair is an anonymous one-line log adrift in space. Write a single line, and the moon's phase and your region are saved with it. A four-character code is your only name.
■ Write one line
Write when you feel like it; it doesn't have to be every day. Public and friends-only logs are up to 140 characters, and private logs can run longer. Each time, you choose public, friends, or private. A private log appears nowhere but your own records — a diary no one else can see. You can add a photo, or attach music with a YouTube link.
■ Logs get observed
A public log no one has read stays veiled. The first traveler to open it becomes its first observer, marked on the log for good. Once observed, a log can't be undone — so opening one carries weight, and so does leaving one.
■ A voyage from planet to planet
Build up logs and a launch window opens to the next planet. From Earth through Mars, Jupiter, and Saturn, out to interstellar space. There's no rush — if you stop writing, the voyage waits where you left it.
■ Alone, but not only alone
Under the same moon phase, other travelers' anonymous logs drift too. Leave a like on a line that reaches you, and a comment on one that's been observed. Save the ones you want to keep close. With people you know, become friends and share friends-only logs.
■ Anonymous to the end
No name, no profile. A four-character code is all there is, and a nickname, if you set one, is seen only by you. Location is kept to a rough region — never your exact coordinates. A recovery code lets you return on a new device.
■ Safe and quiet
Logs and comments can be reported and blocked, and text is checked automatically when posted. The screen stays quiet — a dark sky, the moon's phase, and your line.
Today, one line is enough.
