Eat by feel,
not by the numbers.

The living food pyramid

The pyramid isn't a table – it's a picture of your day. Every tier – drinks, fruit & vegetables, grains & potatoes, protein & dairy, oils & fats, extras – has fillable slots. You tap them instead of typing numbers; the shape itself is the recommendation: wide at the bottom, narrow at the top.

It adapts to your diet – balanced, vegetarian, vegan, low-carb or your own – and fills in automatically as you log foods. Filled slots glow softly; empty ones stay gentle outlines.

Nutrient tracker with an offline catalog

Over 1,640 curated foods are built into the app – brands, ready meals, regional and international dishes, fresh ingredients – fully offline and without an account. The food names are localized in seven languages (German, English, Spanish, French, Italian, Portuguese, Chinese). Set calorie and macro goals (carbs, protein, fat), log meals by breakfast, lunch, dinner and snack, and keep an eye on your daily dashboard with progress bars.

Entry is gram-precise – through a gram input field, portion chips and plus/minus steppers, with a live nutrition preview before you save. Fast logging via favorites, "recent" and "copy yesterday". If you like, ArcVita calculates your goals automatically with Mifflin-St Jeor from your body data, and credits exercise calories on training days – opt-in, you stay in control.

Barcode scanner with an offline catalog

Scan a package barcode and ArcVita finds the product in a bundled offline product catalog (a subset of Open Food Facts) – with no network connection at all. The scanned product lands in your meal with its nutrition values; you set the amount and portion gram-precise, as usual.

Micronutrients in detail

Optionally, ArcVita shows a per-day detail view with micronutrients: fiber, sugar, saturated fat, sodium, potassium, calcium, iron, magnesium, and vitamin C and D. The values come from the public-domain USDA data. The view is opt-in – if you'd rather keep the lean core, simply leave it off.

Also optional, you can track caffeine and alcohol if those values matter to you.

Your own recipes, easily logged

Build your own recipes from ingredients and servings; ArcVita scales up the nutrition and logs the recipe as a single, scaled entry – instead of typing every ingredient one by one. Recipes can also be imported: from pasted text or from a website link you send to ArcVita via Android's share function.

Intermittent fasting timer

If intermittent fasting suits you, a calm timer guides you through the common windows – 16:8, 18:6, 20:4 or OMAD. You see the elapsed and remaining time at a glance, and gentle streaks keep you going without piling on pressure.

Drink enough, effortlessly

Instead of abstract milliliters you use real vessels – glass, cup, bottle or your own. One tap is one drink. Set your goal with a slider, an undo button catches mis-taps, and gentle reminders help you through the day. The level is mirrored in the pyramid's base, too.

A modular health diary

The core is a quick daily check-in: five mood faces, a strain slider from 0 to 10, and a free-form day note. Beyond that, you unlock exactly the modules that fit you – no more, no less:

• Cycle – period and intensity, manual and local; Insights includes a cycle prognosis.
• Medication – fixed doses (morning/noon/evening) to check off, plus as-needed meds with a timestamp.
• Blood pressure – readings with systolic, diastolic and pulse.
• Weight – your trend over time, logged locally.
• Blood glucose – readings to keep track of.
• Skin & symptoms – daily condition from normal to irritated.
• Digestion – normal, diarrhea or constipation; the insights surface links to your food, such as yesterday’s fat or fiber.
• Shift – your own shift types with colors, as an extra correlation axis.
• Custom trackers – set up freely defined trackers for whatever else you want to keep an eye on.

Movement & sleep, automatically

With your explicit permission, ArcVita reads steps, exercise minutes and sleep from Health Connect – read-only, local, revocable any time. Movement and sleep flow into your diary and insights without you typing a thing.

Insights – no AI, no server

ArcVita connects every building block and looks for patterns locally: like "on low-sleep days your strain is higher" or "migraine two days before the period". It also spots next-day effects and sums up your week – with simple statistics, entirely on the device. And always with the honest reminder: a correlation is not a cause.

Reminders that think along

Create your own reminders – text, time, weekdays. Optionally only under conditions: "only if I've had too little to drink today", "if I slept little last night" or "if I haven't logged anything yet". So they never nag without reason.

Every day is reachable

Forgot to log something yesterday? With the arrows or the date picker you jump to any past day in Food, Drinks and Diary and fill it in. One shared day for the whole app – no searching, no fuss.

Your data stays yours

Everything is stored encrypted on your device (SQLCipher). No mandatory cloud, no account, no telemetry, no ads, no trackers. For moving to a new phone there's an encrypted backup with your own password, and for a doctor's visit an export as PDF (summary) or CSV (all daily values).

In your language, in your mode

ArcVita speaks German, English, Spanish, French, Italian and Chinese – and follows your system language. The dark mode is genuinely dark: easy on the eyes for light sensitivity and migraine, not just inverted light. A warm, encouraging tone, never preachy, no mascot.
