Frequently asked questions

Everything you want to know about keto and Ketocat.

What is the keto diet and how does it work?
The ketogenic (keto) diet is a very low-carb, high-fat diet. By restricting carbohydrates to under 20–50 grams per day, you force your body to burn fat instead of glucose. This produces ketones — your body's alternative fuel source — a state called ketosis. The result can be faster fat burning, reduced hunger, and more stable energy levels throughout the day.
How many carbs per day on keto?
Most people aim for under 20–50 grams of net carbs per day to reach and stay in ketosis. Net carbs are calculated by subtracting dietary fiber from total carbohydrates. Ketocat lets you choose between strict keto (20g), moderate low-carb (60g), liberal low-carb (140g), or a custom limit — and tracks everything automatically.
How do I find the carb level that suits me?
Bodies respond differently to low-carb — some people thrive on strict keto, others feel better with a bit more carbs. Instead of guessing, Ketocat lets you find the answer in your own data: track your energy level daily with one tap and see it alongside your food log, weight, waist and training. The weekly report sums up the patterns so you can adjust your carb limit based on how your body actually responds.
Is Ketocat free?
You get a 12-day free trial with full access — no credit card required. After the trial, plans start at $6.99/month or $49.99/year ($4.17/month). You can cancel anytime and export or delete your data.
Does Ketocat work on iPhone and Android?
Yes! Ketocat is a Progressive Web App (PWA) that works on any device with a browser — iPhone, Android, tablet, and desktop. Add it to your home screen for a native app-like experience, no App Store or Google Play required. It also works offline.
What is the difference between keto and low-carb?
Low-carb is a broad term for diets that reduce carbohydrate intake, typically to 50–150 grams per day. The ketogenic (keto) diet is a stricter form where carbs are restricted enough to trigger ketosis. Ketocat supports both approaches with adjustable daily carb limits.
Can I track intermittent fasting in the app?
Yes — Ketocat has a built-in fasting tracker for intermittent fasting. Start a fast with one tap, see your fasting duration in real time, and combine periodic fasting with your low-carb diet for best results.
What are Keto Points?
Keto Points (KP) are earned by completing daily missions — logging food, staying under your carb limit, building streaks, and more. You spend KP on real-life rewards you set for yourself (a coffee, a movie, a spa day) and on cosmetic items in the in-app shop.
