App information

What the app is, why it matters, and how it helps.

This section mirrors the spirit of the in-app info area — giving users a clear explanation of why added sugar awareness matters, what counts as added sugar, and why the app focuses on added sugar instead of every type of sugar.

What counts as added sugar?

Added sugar means sugar that is added during processing, preparation, or serving — not the natural sugar found inside whole fruit, plain milk, or other unsweetened whole foods.

  • Examples include table sugar, syrups, sweeteners in soda, sweet coffee drinks, desserts, candy, flavored yogurt, pastries, sauces, cereals, and many packaged snacks.
  • The app is focused on added sugar only, so users can track the part of sugar intake that is most hidden in everyday products.
  • This keeps the experience simpler and more actionable than tracking every type of sugar.

Why is juice often treated like added sugar behaviorally?

Even when juice contains naturally derived sugar, it can behave more like a sugary product in real life because much of the fruit’s original fiber structure is removed and the sugar becomes easier to consume quickly.

  • People can drink a large amount of sugar from juice faster than they would eat the equivalent whole fruit.
  • Juice often feels healthy, so it is easy to underestimate how much sugar it contributes to the day.
  • That is why knowsugar helps users pay attention to sweet drinks and juice-like products as part of better daily awareness.

Why track added sugar?

Added sugar can build up quietly through drinks, snacks, desserts, sauces, and packaged foods. knowsugar helps make that invisible number visible, so users can build awareness and make better daily choices.

  • Focus on added sugar only, not naturally occurring sugars from foods like fruit or milk.
  • Spot repeat sources that push intake higher than expected.
  • Use simple daily tracking as a practical behavior-change tool.

How the app works

Log food items, see how the ring changes, and use the day’s numbers to stay aware of your intake. knowsugar is built to reduce complexity, not add more of it.

Fast logging Added sugar search API Daily ring Today / Limit / Excess

Personalized added sugar limit

The app provides a personalized daily added sugar limit to give users a clear upper boundary. The goal is not perfection — it is awareness, consistency, and a practical way to make day-to-day decisions.

  • Personalized during onboarding.
  • Displayed across the app for simple daily reference.
  • Used in graphs and summaries to show progress clearly.

Added Sugar Score & Sugar Habits

knowsugar includes a score-based and trend-based view of progress. This adds a light layer of motivation while helping users understand patterns over 7-day and 30-day periods.

  • Added Sugar Score: a gamified way to stay engaged and compare progress over time.
  • Sugar Habits: trend views and insights that help users see repeated behaviors and major sugar sources.
  • Shareable reports: snapshots that make progress feel tangible and easy to review.

The knowsugar added sugar search API

The app includes a dedicated added sugar search API designed specifically around sugary foods and drinks. This helps keep search results more relevant to the app’s purpose and creates room for the database to grow over time.

  • Built to expand and cover more sugary foods, drinks, desserts, snacks, sauces, and packaged products.
  • Designed to improve search quality and make logging faster for everyday users.
  • Supports the long-term vision of making added sugar data more useful, searchable, and easier to understand.
Why added sugar only

We track what matters.

knowsugar focuses on added sugars so users can understand the sugars that are easiest to miss in everyday drinks, snacks, desserts, sauces, and packaged foods.

Added sugar, not every sugar.

knowsugar focuses on added sugars — the sugars and syrups added to drinks, desserts, snacks, sauces, and packaged foods. These are often the sugars that add up quickly and are easy to underestimate.

We do not count the natural sugars found in whole fruit, plain milk, or unsweetened whole foods, because those foods also provide nutrients, fiber, protein, or natural structure that can support steady energy.

By focusing only on added sugar, knowsugar keeps your daily number simple, practical, and easier to act on.

Added sugar Comes from sweeteners added to drinks, desserts, snacks, sauces, and packaged foods. These can add up quickly and make it harder to stay within your daily goal.

GLP-1 companion analysis

See meal patterns, daily totals, and weekly trends in one view.

The GLP-1 companion view is designed to make added sugar easier to understand meal by meal, while keeping the language educational and focused on awareness.

A clearer way to review added sugar patterns.

For GLP-1 users, knowsugar organizes added sugar around two simple guides: a 10g meal guide and a 30g daily guide. The weekly analysis view helps users see which meals stayed within range, which meals went higher, and how the week is trending overall.

This is not medical guidance. It is a practical wellness view that helps users notice patterns, compare days, and understand where added sugar is coming from.

1

Meal-level visibility: each entry is tracked as M1, M2, M3, and so on, making it easier to review what happened during the day.

2

Weekly analysis: stacked columns show daily totals and meal-level patterns, with a 30g daily guide for easy comparison.

3

Report-ready data: meal labels, home/outside tags, weekly totals, and top added sugar sources can support clearer habit reports over time.

Why knowsugar focuses on added sugar.

knowsugar keeps tracking simple by focusing on added sugars — the sweeteners added to drinks, desserts, snacks, sauces, and packaged foods.

We track what matters.

knowsugar focuses on added sugars because these are often the sugars that are easiest to overlook and quickest to add up during the day.

For GLP-1 users, this can be especially useful when meals are smaller or more intentional. The app helps organize added sugar awareness around meal entries, daily totals, and weekly patterns.

We do not count the natural sugars found in whole fruit, plain milk, or unsweetened whole foods, because those foods also provide nutrients, fiber, protein, or natural structure that can support steady energy.

Why only added sugar?

Added sugar: comes from sweeteners added to drinks, desserts, snacks, sauces, and packaged foods. These can add up quickly and may make it harder to stay within your daily goal.

Natural sugar: is found in whole foods like fruit and plain milk. These foods also provide nutrients, fiber, protein, or natural structure that can support steady energy.

For GLP-1 companion mode, knowsugar uses a 30g daily guide and a 10g meal guide to make added sugar easier to see meal by meal.

knowsugar is a wellness and education tool. It is not medical advice, diagnosis, treatment, medication guidance, or a replacement for professional care.

How it works

Three simple steps, designed for real life.

knowsugar was built to stay simple enough for everyday use, while still giving users meaningful information about their added sugar patterns.

1

Set up your profile

Answer a few basic questions so the app can estimate a personalized added sugar limit and tailor the experience to the user.

2

Log what you eat and drink

Use the added sugar search API or type your own item and amount. Each log updates the ring and daily totals immediately.

3

Learn from your patterns

Check your score, habit trends, and reports to see where added sugar is coming from — and where small changes can make the biggest difference.

Why knowsugar

A focused approach to behavior change.

Most nutrition apps try to track everything. knowsugar focuses on one number that matters in a way users can understand quickly and act on consistently.

“The goal is not to create another overwhelming nutrition tracker. It is to help people become more aware of added sugar and make healthier decisions with less friction.”

knowsugar is built for everyday users, families, and anyone who wants a simpler way to build better food awareness. It is especially helpful for people who want practical prevention and habit insight rather than information overload.
