Get going
in a minute.

Build your app, install it, and run it offline. Here’s the whole flow.

01 · Build it

On the Build page, name your app and pick 3 to 8 tools. Give each a color if you like, decide whether MARK rides along, and you’ll get an installable link.

02 · Install it

Open the app and add it to your home screen — the Share menu in Safari on iPhone, the menu in Chrome on Android. It runs full-screen and offline.

03 · Live the home screen

Home shows today only: your split, calories against goal, water, tasks, goals, and more — each in its own color. Tap any card to jump straight to that tool.

04 · Logging a lift

In Lifts, build your split (add, rename, reorder days) and tap a day to set it as today. Hit Start, name the session, then log every set inline — weight, reps, done. Add notes per exercise.

05 · Sharing a workout

Open any past session and tap Share to generate a clean Instagram-Story graphic — your split, top sets, and PRs, ready to post.

06 · Asking MARK

Tap the MARK button on any screen. Ask anything, or just tell it what you ate — it answers with your context in mind and can log it for you.
