ASK why lower calories
Trend's moving, just slower than the pace we set. 70 calories is deliberately small so training doesn't take the hit. We look again Sunday.

A weight coach that learns your metabolism

Zolt does more than reply.

It reads and writes the same health system behind the Zolt app—your meals, targets, weigh-ins, goal, reminders, and progress.

01

Trend, not noise

Zolt looks past daily scale swings and focuses on the weight trend that actually shows progress.

02

Targets that adapt

Your calorie and macro targets can evolve from your results instead of staying frozen in a calculator.

03

A coach you can question

Ask why a target changed, request a different pace, or talk through a plateau in plain English.

Built on your trend

The conversation has your real progress behind it.

Zolt uses your weigh-ins, trend weight, food logs, active goal, and current targets—not a disconnected chatbot profile—to guide each check-in.

The agent is a Zolt interface—not a separate chatbot.

Start in iMessage, then open the app whenever you want the full graphs, history, and controls.

How it works

Start with a text. Build a real plan.

01

Tell Zolt your goal

Choose whether you want to lose, gain, or maintain weight.

02

Send weight and meals

A little consistent data lets Zolt learn how your body is responding.

03

Check in each week

Review your trend and tune the plan without rebuilding it yourself.

Stop following a calculator from six weeks ago.

Start a conversation with a coach that can keep up with your progress.
