AI meal planning · UK supermarket prices

Plan the week's meals. Pay the least for them.

DietAisle builds a weekly plan around your macros, then works out which supermarket near you sells the lot for less. Free, private, works offline.

Eating to your goals, without the spreadsheet

AI plans built around your macros

Tell DietAisle your calorie and macro targets — or pick a preset like Intermittent Fasting or Bulking — and it generates a full week of meals that actually add up. Swap anything you don't fancy.

It knows where's cheapest

Your whole shopping list, priced per store — Lidl, Aldi, Tesco, ASDA and more — with the stores actually near you. One verdict: where to go and what you'll save.

Scan a receipt, learn your real prices

Point your camera at a receipt and DietAisle reads every line, matches the nutrition, and remembers what you actually paid. Barcode scanning fills in the rest. The more you scan, the sharper its price comparisons get.

A shopping list that knows your rhythm

Staples carry quiet restock reminders — so oats go on the list every few weeks without you thinking about it, and nothing runs out mid-week.

Fair questions, straight answers

Is DietAisle free?

Yes. Meal planning, price comparison, receipt and barcode scanning are all free, with no ads. You just need a free account so your data can follow you across devices.

Where does my data live?

In your account. Your plans, product database and prices live in your own row in the database and sync to every device you sign in on. Your device keeps a copy so the app still works offline.

Which supermarkets does it cover?

Price comparison covers the big UK names — Lidl, Aldi, Tesco, ASDA, Sainsbury's, Morrisons and more — and learns your local prices from the receipts you scan.

Does it track my location?

Only when you tap "find stores near me", and only for that one lookup. There's no background tracking — the app can't do it even if it wanted to, and it doesn't want to.

How do I install it on my phone?

Open the app in your browser, then: on iPhone, tap Share → "Add to Home Screen". On Android, tap the install prompt or menu → "Install app". It then opens full-screen like any other app and works offline.

Eat to your goals. Keep the difference.

Your first weekly plan takes about a minute.
