Track calories and macros by text.

Biblo is a calorie tracker you use in iMessage. Send a food photo or describe your meal, get calorie and macro estimates, and make corrections in the same conversation.

Free on iPhone. No separate download needed to get started.

How to track a meal with Biblo

1. Open the conversation

Tap Text Biblo on your iPhone. On a computer, scan the QR code to open the conversation on your phone. Send your first message to get going.

2. Send a photo or type what you ate

A photo is useful when the meal is in front of you. A description works when you've already eaten or do not want to take a picture.

For example, you could send:

Two eggs, one slice of toast, and a banana.

3. Add the details you know

Portions and preparation matter to the estimate. Mention details that may not be obvious, such as how much you ate, whether you added a sauce, or the amount shown on a package.

For example:

I used butter on the toast.

You do not need a special format. Describe the meal as you would in a message to someone else.

4. Review the calorie and macro estimate

Biblo returns estimated calories, protein, carbs, and fat. Check that it understood the meal and portion before relying on the total.

5. Correct anything that changed

You might send a full plate and then eat only part of it. Follow up in the same conversation:

I only ate half the rice.

Check Biblo's updated estimate so the log reflects what you actually ate.

6. Ask for your daily total

After logging meals, ask:

What have I eaten today?

Or ask for your calorie and macro totals. The summary reflects what you've sent Biblo; it is not an automatic record of food you have not logged.

Photo tracking and text tracking work together

You do not have to choose one method for the whole day. Send a breakfast description, a lunch photo, and a follow-up about dinner.

Text is especially useful for details a picture does not capture. A photo can show a bowl of food, while a message can explain that you ate half or added something after taking it.

What to know about the numbers

Photo-based food tracking produces estimates, not exact measurements. Portion sizes, recipes, cooking oil, and hidden ingredients can affect the result. A typed description can also be incomplete.

More detail can help Biblo understand what you mean, but it does not turn an estimate into a precise measurement. Review the result, correct mistakes, and use the information with that limitation in mind.

Biblo is not a substitute for individualized advice from a qualified health professional.

Do I need an app to track macros with Biblo?

No separate download is needed for the current texting experience. Biblo's food tracking happens in Messages on your iPhone. It reports protein, carbs, and fat alongside the calorie estimate.

A companion app is planned to complement messaging. You can use the current food-tracking experience without waiting for it.

Android is not supported by this experience yet. You can join the Android waitlist.

More than a different place to enter food

Our goal is a personal AI fitness agent that can connect food tracking with helpful coaching and actions you approve. The food log should be useful context, not another chore to maintain for its own sake.
