About this app

NicoFit is a health tracking app that lets you manage your diet, workouts, and daily condition all in one place.

"It's hard to keep up with tracking." The biggest reason is the hassle. NicoFit, built on AI, drastically reduces that hassle. Just take a picture, talk to it, that's it. No complicated settings or detailed calculations required. Anyone can easily start using it today.

【Complete Management: 3 in One】

・Meal Management: Simply take a picture, and the AI ​​automatically estimates calories and PFC (protein, fat, carbohydrates). Whether you're eating out or buying convenience store food, you can record it in 3 seconds if the product is pre-registered in the database of over 70,000 food items.

・Workout Recording: Supports standard exercises including bodyweight, dumbbells, and machines. It automatically recalls your previous weight and reps, so you can use just your smartphone at the gym. It also includes a built-in rest timer between sets and automatically calculates your estimated 1RM for the BIG3 exercises. The more you continue, the more you'll see your progress.

* Daily Condition
Record your weight, body fat, sleep, mood, and other daily conditions. The 7-day and 30-day moving averages smoothly display trends, allowing you to understand your progress without being overly affected by short-term fluctuations.

* Three Input Methods: Choose the Easiest Way

* Photo: Simply take a picture of your food. The AI ​​will estimate the dish name, calories, and macronutrient content (PFC).
* Voice: Simply say, "Natto rice and miso soup for breakfast, salad chicken for lunch." The AI ​​will break it down and record it.
* Barcode: Scan the JAN code of commercially available products to record official nutritional information directly.

We've minimized the need to type on the keyboard.

* AI Makes Recording Easy

NicoFit's AI takes care of your record-keeping. You are the star.

* Estimates nutrition from a single photo and a short audio message, eliminating the need for manual input.
* Automatically calculates daily target calories, recommended macronutrients (PFC), and achievement pace by working backward from your goal.
* Every morning, it gently delivers "Today's Message" based on recent data (non-reprimanding, sustainable coaching).
* Weekly reports summarizing your records allow you to objectively view yourself.

You're the one who puts in the effort. The AI ​​handles the tedious tasks.

[Supports Health Checkup Records]

By recording your annual health checkup results, you can review them alongside your weight and diet records. The Standard and Pair plans include a 3-month lifestyle improvement plan and monthly review summaries created by the AI. Please consult your doctor regarding the interpretation of numerical data and treatment decisions.

[Automatic Step Counting with Healthcare Integration]

By integrating with iPhone's "Health" app and Android's "Health Connect," you can automatically import steps, weight, and sleep data. It estimates your daily activity level from your steps and displays your calorie balance with your meals on the home screen. It adjusts to avoid double-counting with manually entered aerobic exercise, so you don't have to worry about inflated numbers.


[The convenience of having everything in one app]

No more separate apps for meals, workouts, and weight. Everything is visible on one screen, so you can see how you did at a glance. All your scattered records are consolidated into one.


[Easy to continue together, even as a couple]

With the Pair plan, you can share your records with your partner. Encourage each other and make it a habit together. This is a feature exclusive to NicoFit.


[Seven color themes to choose from]

Coral, mint, sky blue, lavender, orange, yellow, and pink. Change the app's color to match your mood or your partner.
