## What is Tact?

Ever had to stop running because of your knees? That's not giving up — it's changing direction. Brisk walking lets you train seriously without wearing down your joints, but Apple Watch has never given outdoor walking a real pace target. Intervals were built for running only, and even that wasn't great.

Tact fills that gap.

We designed it to stay quiet during your workout. If you're holding your target pace, your screen and your wrist stay silent. Only when you drift does your wrist tap out a 10-second rhythm to bring you back — then it goes quiet again. Not a trainer that keeps talking, but one that signals only when you need it.

That signal is vibration, not sound. Built so you can feel your pace through your wrist alone, no earbuds needed, even in noisy surroundings. Pace itself is calculated from your walking rhythm, not GPS, so it holds steady even when the signal wavers. And when conditions are genuinely too uncertain to judge, it waits quietly instead of forcing a guess.

Key features:
• Pace-target intervals for outdoor walking — something Apple Watch has never offered
• Silent by default, a 10-second vibration only when you drift — coaching without the nagging
• Joint-friendly brisk-walking interval programs in 3 levels — Easy, Balanced, Challenge
• Personalized stride learning that gets more accurate the more you walk
• Set up once on iPhone, start with a single tap on your Watch
• Heart rate, steps, and distance logged automatically to Apple Health
• One-time purchase, no subscription — pay once, use forever

Built for people who want to walk seriously, without straining their knees.
