Take a picture of your plate. Tainy works out what’s in it and logs it, so you’re not weighing rice or hunting for barcodes. Your day fills up like a glass of water instead of counting down in red.
You’ll spend longer deciding what to eat than writing it down.
Whatever’s in front of you. Bad kitchen lighting and half-finished plates are fine.
It names the dish, estimates the portion and fills in the numbers. If something’s off, change it before you save.
The water level goes up, your budget adjusts, and you get back to eating.
It has read the actual research on nutrition and training, and it answers like a person instead of a search result. Say “I did 40 minutes of pilates” and it’s in your log before you’ve put the mat away.
Their streaks, your streak, and a button for sending someone a bit of encouragement on a rough week. What nobody gets to see is your calorie count or what you ate. That part isn’t shared with anyone.
Calories stay privateYoga, a long walk, an hour of cleaning the flat, dancing while you cook. Write it the way you’d say it and Tainy adds it back to your budget. You don’t need to own a barbell for this to work.
Seven columns of water, one per day, and a line telling you whether you’re roughly on track. Nothing turns red, and missing a Sunday doesn’t undo your month.
Greek salad, tandoori chicken, sashimi, carnitas. Most of it was already keto and nothing was done to it. Every recipe has its net carbs worked out per serving against USDA data, with swaps for dairy, nuts and gluten where they help. Keto mode counts net carbs instead of total, against the same numbers.
What you eat stays in your account. Friends see whether you logged and whether you hit your goal, and that is the whole list. We don’t sell any of it, and there’s no advertiser on the other end of this.
Read the privacy policy →Right now, £24.99 once. That unlocks the app for good — no subscription, no renewals, nothing to cancel.
This is a launch offer and it won’t last. In a few months Tainy moves to a subscription: £6.99 a month or £49.99 a year. So the one-time unlock is currently about half the price of a single year, and it never runs out.
If you buy now, the subscription never applies to you. Not when it launches, not later. We won’t convert your purchase, charge you again, or move something you already had behind a monthly fee. That’s written into our terms, so it isn’t just a promise on a webpage.
One thing: 50 photo scans a month. Analysing a photo runs it through an AI model that costs us money every single time, so an unlimited one-off price isn’t something we could honestly sustain.
Everything else is unlimited and always will be — barcode scanning, searching foods, entering things by hand, re-logging a meal you’ve had before, activities, weight, streaks, friends. Those cost us nothing, so we don’t count them. Between barcodes and one-tap re-logging, most people won’t come close to 50 photos.
Most apps in this category don’t tell you whether there’s a limit at all. We’d rather say the number, and if it turns out to be more generous than we need, we’ll raise it — never lower it for anyone who already bought.
If you ever do run out, the app keeps working normally. You just can’t analyse a new photo until the month ticks over.
We’d rather explain how it works than quote a percentage we haven’t measured.
The calorie and macro figures come from real nutrition databases built on USDA data — they aren’t invented. What the AI does is look at your plate, work out what the foods are, and estimate how much of each is there. That portion estimate is the hard part, and it’s where most of the error comes from. A chicken breast can be 150g or 250g and look much the same in a photo.
So: simple, separated foods do well. Mixed dishes, sauces, and anything where you can’t see the quantity are rougher. Tainy tells you when it’s unsure, and every number is editable before you save — if you know the weight, type it and the maths redoes itself.
Two things make it better over time: scanning a barcode gives you the manufacturer’s exact figures rather than an estimate, and Tainy learns the portions you actually eat, so your regular meals stop being guessed at.
That’s most of the people we built it for. Walks, yoga, dancing, housework: type it in plain English and it counts toward your day.
Yes. Keto mode tracks net carbs instead of total, and there are 71 keto recipes to go with it — free to read, whether or not you ever install the app.
Your food diary is private to you. Friends only see that you logged and whether you hit your goal, never the numbers, and we don’t sell data to anyone. The full details are in the privacy policy.
Leave your email and we’ll send one message on launch day. We won’t do anything else with it.
