One Light
Light leaves at a fixed speed and never stops. Choose the day you said goodbye, and the app works out how far light has carried in that same stretch of time — past the Moon, past the planets, still going. The distance is real astronomy. The journey is a memorial, not an afterlife.
What it does
A real distance, not a comfort
The figure comes from actual astronomical constants. When the hour of the farewell is unknown, the app shows the range instead of inventing precision it does not have.
A place to keep them
Dates, favourite things, small habits, a message. Light a light or add a memory whenever you want — no streaks, no reminders, no pressure to come back.
Fellow travellers, if you want
You can share a name, a species, one trait and a rough month, anonymously. Photos, exact times, your identity and your location never leave the device.
Questions
Does this claim my pet is somewhere out there?
Do I have to share anything publicly?
Is this grief counselling?
