One photo a day. Look back on a calendar and see the change. Free, no account.
■ What is Teiten?
Teiten is a "fixed-point" photo journal: take one photo a day and watch things change over time.
Your pet growing up, a plant getting taller, meals, workout progress, the color of the sky —
build up the small changes of everyday life, one photo a day.
Look back on a calendar full of your photos, and put two photos side by side to see how much has changed.
