Theseus: Plank by Plank
Lifestyle
Free · In‑App Purchases
Every perfect day replaces one plank of your ship. Rebuild yourself, plank by plank — then answer the old question: is she the same ship? Free, no ads, no account.
Rebuild yourself, one plank a day.
Theseus is a habit tracker built on a 2,000-year-old thought experiment. Athens kept the ship of the hero Theseus for centuries, lifting out each plank as it rotted and fastening new timber in its place — until not one original board remained. Was it still the same ship?
Your ship works the same way. Every perfect day — every habit kept — replaces one plank, from the keel up. Miss a day and nothing is lost; the ship never rots, she only waits. At the halfway mark she asks you the philosophers' question, and when the last plank is laid she sails into your Harbor with a name and a date — and you lay a new keel.
(…then THE VOYAGE / THE SHIPYARD / THE TELLING / THE HARBOR / MADE WITH CARE feature sections — full text in the file.)
Keep the ship. Become someone new.
