Astras is a club — your personal AI wellness assistant (about Astras). The calorie counter sits next to lab results, cycle and water tracking and meditations.
Calorie counter
AI calorie counter: calories from a photo of your plate
Astras is an AI wellness app with a calorie counter on its Home screen. Photograph your plate, say what you ate, or type it: Astras estimates the dish, its calories and grams of protein, fat and carbs. You check the portion, save, and the entry lands in one food and water diary with your daily targets.
How the AI calorie counter works
Capture the meal
On the calorie card on Home, tap the camera and photograph your plate, or tap “From library”. On the web you upload a photo. Prefer words? Tap the microphone and say what you ate.
Astras makes an estimate
After a short scan you see “On your plate”: the dish name, the ingredients it recognized, a line about the portion, the calories, and protein, fat and carbs in grams.
You correct it before saving
When the estimate includes a portion weight, change it with − and + (10 g steps up to 100 g, 50 g above) or type the grams; calories and macros recalculate. Then tap “Save” — or “Cancel”.
The day adds up
The card shows what’s left for today and fills three bars — Protein, Fat, Carbs. The entry appears in “Eaten today” on the Nutrition tab with its time.
Logged something twice? “Undo” takes back today’s last entry, and any of today’s entries can be deleted from “Eaten today” after a confirmation that names the dish.
Calorie counter by photo: what the camera handles
- Plates, bowls, snacks: Astras names the dish and lists what it sees. It’s an estimate — a camera can’t weigh food or see butter melted into rice — so we don’t quote an accuracy percentage.
- Packaged food: photograph the label. The per-100 g values are read and one serving is counted; the package weight goes into the note, so you can set the portion you actually ate.
- Not food: Astras says so plainly instead of guessing.
- Camera and depth: on iPhone and Android, Astras opens its own camera with a library button by the shutter. On some phones with a depth sensor (LiDAR, dual camera or ToF) it can measure the distance to the plate as a hint about portion size; a small ruler icon by the number shows when that happened.
- Online only: offline, Astras tells you the photo can’t be recognized; nothing is queued.
- Photos aren’t saved to your diary or account: Astras sends the picture for recognition and keeps only the result. The diary stores the dish, calories, macros and time.
Log food by voice or text
Tap the microphone and talk naturally: “a bowl of oatmeal with a banana and a latte”. You see the transcript as you speak; tap stop, or let the recording end on its own. The result opens in the same review window, so nothing is saved without your OK.
No voice input on your device? A text field opens instead (up to 200 characters). On the web and tablets there are also “Describe what you ate in words” and “Enter calories by hand” buttons. Words are the easiest way to add what a photo can’t show — the oil in the pan, the dressing, the sugar in your coffee. Telling Karina AI in the chat what you ate logs it too.
Food diary app: your day in one place
The Nutrition tab displays your day; you log food on Home:
- a day strip with one segment per meal and its time;
- “Eaten today”: time, dish, calories, with delete;
- Protein · Fat · Carbs with the grams still to go;
- a “Healthy plate” guide: half vegetables and fruit, a quarter protein and fats, a quarter complex carbs;
- “Ideas for the day” and water;
- a food guide with protein, carbs and fat per 100 g (3.5 oz) of cooked food, searchable offline.
History: the calorie card’s chart covers 7, 15, 30, 60 or 90 days; drag a finger across it to see any day. Days you didn’t log show as gaps, not zeros. Reminders: three a day — 8:00 a.m., 12:30 p.m. and 6:30 p.m. by default in English — adjustable in Settings → Notifications. Widget: a “Snap a meal” tile on your home screen opens the camera.
Calories and macros: your daily targets
Astras sets your daily calorie target from sex, age, height, weight and activity level (Passive, Moderate or Active), then applies your goal: Lose weight (−20%), Maintain, or Build muscle (+15%). It never drops below 1,200 cal for women and 1,500 for men. Protein is set in grams per kilogram of body weight, fat is a share of calories, carbs take the rest; “Where this target comes from” shows the table and sources. Change your height, weight, age, sex or activity, and the target recalculates; with pregnancy turned on, “Lose weight” isn’t offered. The free calorie and macro calculator uses the same formula.
Water in one tap, and meal ideas
Pick your glass once — 4, 8, 12, 16.9, 24 or 32 fl oz — and each tap on “+” logs it; the home-screen widget adds water without opening the app (water tracker). “Ideas for the day” suggests a breakfast, lunch, snack, dinner and dessert from Karina’s catalog of 125 dishes with photos, calories and macros — ideas, not a log (healthy recipes).
What’s free and what’s in a plan
- Free for everyone: daily calorie and macro targets, “Where this target comes from”, the history of what you logged, the food guide, meal reminders.
- Start plan: water logging, Karina’s dishes and recipes, weight logging (a new weigh-in updates your targets).
- Plus and higher: recognizing food from a photo, voice or text, and the Karina AI chat. Plans include an AI token allowance per period, shared by chat, food recognition and lab reports, with a counter on the calorie card.
Plans start from $4.99/month — see pricing.
Your food data
Before the first recognition, Astras asks your permission to send food photos and descriptions to an AI provider; turn it off any time in Settings → “Sending data to AI providers”. Your food and water diary is kept in your account, so the web version and a second phone show the same day. No ads in the app, we don’t sell your data for money, and export and account deletion are built in. Ad measurement runs only after you allow it, in every country (California law counts it as “sharing” and a “sale”).
Frequently asked questions
-
It’s an estimate, and we don’t quote an accuracy figure. A photo shows what’s on the plate but not its weight, and it can’t see oil, butter or sugar mixed into the food. So Astras makes its reasoning visible: it names the dish, lists the ingredients it recognized and describes the portion. When the estimate includes a portion weight, you can change it before saving and the numbers recalculate. For packaged food, photograph the label. For home cooking, mention cooking fat and sauces in words.
-
Part of it is. Your daily calorie and macro targets, the history of what you logged, the food guide and meal reminders are free for everyone. Recognizing food from a photo, voice or text runs on AI and is part of the Plus plan and higher; water logging, Karina’s recipes and weight logging are in the Start plan. Plans start from $4.99/month. Each plan includes an AI token allowance per period, with a counter on the calorie card.
-
Yes. Tap the microphone on the calorie card and say what you ate — “Greek yogurt with berries and a handful of almonds” is enough. You see the transcript as you speak; tap stop or let the recording end on its own. Astras turns the description into a dish with calories, protein, fat and carbs and opens it for review, like a photo, so nothing is saved without your OK. Without voice input on your device, a text field opens instead. Voice and text recognition are part of the Plus plan and higher.
-
Yes — photograph the package or its label. Astras reads the nutrition values per 100 g from the label and counts one serving, while the weight of the whole package goes into the note. That matters because a bag of granola or a box of crackers is rarely one portion. In the review window you set the portion weight you actually ate, and the calories and macros follow. If the label can’t be read, type the product and the amount in words; the same review window opens.
-
No. Astras sends a food photo for recognition and doesn’t save it to your diary or your account. Your diary keeps only the result you saved: dish name, calories, protein, fat, carbs and time. Before the first recognition, Astras asks permission to send food photos and descriptions to an AI provider; you can switch that off in Settings. The diary is kept in your account; you can export it or delete the account with all its data.
-
Yes. Every saved entry carries protein, fat and carbs in grams, and the calorie card shows three bars as “N of M g” against your daily targets; the Nutrition tab shows the grams still to go. Targets follow your goal and activity: protein is set in grams per kilogram of body weight and rises when you’re losing weight or building muscle, fat is a share of calories with a minimum, carbs take the rest. Tap a macro on the Nutrition tab to open the food guide. The macro calculator shows your numbers in advance.
-
Recognition doesn’t. Photo, voice and text estimates are made online, so offline Astras tells you the photo can’t be recognized and doesn’t save anything for later. What already lives on your phone still works: your daily target, today’s totals and macro bars, the history chart, and the food guide, whose search runs on the device. Once you’re back online, take the photo again; the diary then syncs to your account.
-
Astras runs on iPhone, Android and the web at astras.club, with one account and one diary across them. The interface comes in English, Spanish, French, German, Italian, Turkish, Russian and Ukrainian, and food estimates come back in your app language. You sign in with a one-time code sent to your email, or with Apple, Google or Facebook; Astras is for ages 16 and up. On the web, you upload a food photo instead of opening the camera.
-
No. Astras is a wellness app that helps you see what you eat; it doesn’t sell a diet and doesn’t promise weight loss. You choose a goal — Lose weight, Maintain or Build muscle — and the app sets a calorie and macro target with floors it won’t go below: 1,200 cal for women, 1,500 for men, and enough for your minimum protein, fat and carbs. During pregnancy “Lose weight” isn’t offered. Karina AI can make mistakes and doesn’t replace a doctor. With a medical condition or a history of an eating disorder, check with a professional first.
