will you make it? thereby knows.

iPhone, with an Apple Watch companion · $1.99 one-time · in TestFlight beta

You have to be somewhere at 3:00. thereby watches your pace the whole way there and tells you, continuously, whether you’ll make it — and nudges you the moment you start to slip. No more re-checking a maps app and doing deadline arithmetic in your head.

What it does

  • Tell it where you’re going and when you need to be there.
  • It tracks your pace against the route — walking, cycling, or driving — and keeps a live verdict: early, on time, or slipping.
  • If you dawdle, it says so while there’s still time to fix it.
  • Keeps working in the background with the screen locked; a glance at your wrist is enough.
  • No deadline? An anytime mode just keeps you posted on when you’ll arrive.

Where to get it

thereby is in TestFlight beta, headed for the App Store. One-time $1.99 — no subscription, no account.
