Weight management that connects to your medication
100% free. No credit card needed.
What you can track for weight loss
- Weigh-ins with body fat and muscle mass, in kg or lb.
- Progress to your goal weight, your weekly pace and a projected date at your current pace.
- Daily check-ins for hunger, energy, mood, protein and water.
- Protein and lean mass targets based on your goal weight.
- Reports you can share with your doctor.
Use it with your own AI assistant
Ask your assistant how far you are from your goal, or to write your weekly progress report.
Smart Cycle has a built-in MCP server, so ChatGPT, Claude, Gemini, Grok or Mistral can read your data and, if you allow it, log doses, weight and labs by chat. Ask for a weekly report, when your next dose is due or which labs are out of range. You choose read-only or read and edit access, and you can switch it off at any time.
The built-in AI tools can also read a photo of a lab report and write your progress report, using your own free Gemini or Mistral key.
Questions about weight management in Smart Cycle
How does Smart Cycle estimate when I will reach my goal?
It draws a straight line through your recent weigh-ins and shows when that line reaches your goal. It is a rough projection, not a promise.
Can I use it without a GLP-1 or TRT?
Yes. Weight, labs and daily check-ins work on their own, and you can add a medication whenever you start one.
Can I share my progress with my doctor?
Yes. You can create a report or a read-only link for your clinician.
Is Smart Cycle really free?
Yes. Smart Cycle is 100% free to use and needs no credit card. Your health data is yours and is never sold.
Can I use ChatGPT, Claude or Gemini with my weight data?
Yes. Smart Cycle has a built-in MCP server, so ChatGPT, Claude, Gemini, Grok or Mistral can read your data and, if you allow it, log weigh-ins and check-ins by chat.
Is Smart Cycle medical advice?
No. It is a personal tracking tool. Talk to your clinician before you start, stop or change any treatment.
