Is there anyone like me who has fallen into countless pitfalls trying to manage their diet?
I've downloaded seven or eight calorie tracking apps, and every meal felt like doing research: eating a bowl of noodles meant searching "beef noodles raw weight vs cooked weight," adding a marinated egg required looking up calories separately, and ordering takeout was the most frustrating—the "small portion" from the restaurant never matched the "standard portion" in the app, and estimating more or less was purely a guessing game. By the time I finished all this, the food was cold, and I couldn't stick with it for more than a week before giving up out of sheer annoyance.
That is, until I discovered the treasure that is EtinAI—it really is just a matter of taking a photo. How many calories, how much protein, how many carbs—it calculates it all clearly in 3 seconds. After using it once, I thought: If this had been around earlier, who would bother with manual tracking?
No searching, no calculating—just pick up your phone and you're done
The first time I used EtinAI, I was even a little thrown off by how simple it was.
No lengthy registration process, no need to fill in a dozen body metrics—just download, log in, and within seconds you're on the shooting interface. There's zero learning curve. The official claim of "2 minutes to get started, seconds to be ready" is no exaggeration—just open the app and start shooting. It's extremely beginner-friendly.
Point your camera at the plate, press the shutter, and 3 seconds later, a complete nutritional report appears. Not just total calories, but a clear breakdown of the three macronutrients: protein, carbohydrates, and fat. It can even identify how many grams of rice and roughly how much oil is in the dish.
I tested it in various complex scenarios: two meats and one veg from the company cafeteria, takeout mala xiang guo, homemade mixed soup, and even a barbecue platter with friends on the weekend—it accurately identified every ingredient. What used to take 5 minutes of manual entry is now done with a single snap. Your meal ritual isn't interrupted, and your dietary record is completed effortlessly.
No wonder it has earned a 4.9 rating on the App Store and over 100,000 downloads—truly useful tools always work by subtraction.
Exclusive 5×5cm scale: accuracy that sets it apart
Many people who have used AI calorie recognition tools complain most about inaccuracy: the same bowl of rice might be calculated as 150 calories one time and 200 the next, with portion sizes guessed at random by the AI.
EtinAI's core advantage is its exclusive 5×5 cm reference scale technology.
The shooting interface has a fixed-size box. You just place any object of known size (like an egg, a standard-sized rib, or even a coin) inside the box, and the AI uses it as a reference to accurately calculate the actual weight of the entire dish, solving the root problem of inaccurate weight estimation.
In horizontal tests on the official website, its recognition accuracy for Indian food reached 94.7%, far surpassing similar products. I personally tested it for over half a month on everyday Chinese home-cooked meals, and the error margin was consistently very small. Even details like sauce on dishes or sprinkled sesame seeds are factored into the calorie count—the precision is truly impressive.
These details are what make you want to keep using it
There are plenty of calorie tools out there, but few that keep you engaged long-term. What won me over most about EtinAI is its sense of proportion in user experience.
First is the reassuring privacy. It emphasizes a "privacy-first design." Your dietary data belongs entirely to you—no messy background tracking, no using your data for ad targeting. Using it feels safe.
Second is full cross-platform syncing. It's available on iPhone, iPad, and Android. Log in with the same account and sync data across all devices. Snap photos on your phone during the day, and review your daily intake on your tablet at night—it all flows seamlessly.
Most importantly, the basic features are permanently free. Core functions like daily photo calorie recognition, viewing nutrition facts, and logging a food diary are completely free to use—no ad pop-ups, no nagging to upgrade to premium. Only when you need more advanced features do you upgrade on demand. It's very user-friendly for the average person.
It's not just about calculating calories—it helps you eat well
After using it for a while, I realized that the change EtinAI brings goes far beyond just "knowing how many calories you ate."
Before, I lived in dietary anxiety: I'd agonize over eating a piece of cake, then feel guilty afterward, only to end up binge-eating at night—a vicious cycle. Now, I just take a photo of whatever I want to eat, know its calorie count, and slightly adjust other meals that day. No more fighting with food.
It has also gradually opened my eyes to my eating habits: I was eating way too many carbs and far too little protein; that afternoon milk tea was almost equivalent to half a bowl of rice in calories. Without deliberately dieting, just fine-tuning my dietary structure based on data, I feel much lighter and better overall.
Ultimately, a good dietary management tool doesn't rely on willpower to force you to stick with it—it's so lightweight that you barely notice it's there, naturally blending into your daily meals.
If you've tried countless times to track your diet and given up halfway, if you've lost patience with inaccurate calorie estimates and tedious operations, give EtinAI a try. Something that can be done with just a photo—don't make it hard on yourself anymore.
