A budget meal planning app is one that builds your weekly meals around a spending limit and shows what the shop will actually cost before you go. The distinction that matters in 2026 is whether an app uses real supermarket prices or generic estimates — and whether it also plans around your nutrition targets, which most don't.
We build one of these apps, so read this with that in mind. We've tried to make it genuinely useful rather than a lap of honour: there are three points below where a different app is the better answer, and we've said so plainly. All figures were checked in July 2026 and prices change — verify before you commit.
The short version
| App | Real UK prices? | Macro-based planning? | Cost |
|---|---|---|---|
| MUNCH | Claims live prices (Aldi, Lidl, Tesco, Sainsbury's) | No — displays some nutrition, doesn't plan to targets | Free |
| Mealia | Yes — builds your actual basket (Tesco, Asda, Sainsbury's, Morrisons) | No | ~£5–8/month |
| Cherrypick | Yes — basket integration (Tesco, Asda, Sainsbury's) | No | Free, with paid tiers |
| MOB | No price data at all | No — shows macros, can't filter or plan by them | £6.99/month |
| Samsung Food | No | Nutrition info per recipe only | Free |
| Eat This Much | US prices only — not useful in the UK | Yes | ~$5/month |
| Plan X Prep | Yes — costed against Aldi, Tesco, Sainsbury's, Asda | Yes | £6.99/month (launching) |
The gap almost every app has
Here's the pattern once you line them up: apps are good at money or good at nutrition, almost never both.
The basket-builders — Mealia, Cherrypick — are genuinely impressive at the money half. They connect to your supermarket account and fill your online trolley from your meal plan. That's a real feat of engineering and it saves a genuine chore. But ask them to build your week around 140g of protein a day and they can't; nutrition isn't what they're for.
The nutrition apps have the opposite problem. Eat This Much has planned meals to macro targets for over a decade and does it well — but its cost estimates are in dollars against American grocery prices, which makes the budget feature close to meaningless for a shopper in Sheffield.
And the biggest UK name, MOB, sits in a third category: excellent recipes, no price layer whatsoever. Its own users have spent two years asking for calorie and protein filtering in App Store reviews.
When a different app is the better choice
If you shop online and want the basket filled for you: use Mealia or Cherrypick. Neither we nor anyone else can match a one-tap trolley at Tesco or Asda, and we don't pretend to — Plan X Prep gives you a priced, aisle-sorted list to shop from, not an automated checkout. If that automation is the thing you want most, they're the answer today.
If you want recipes and inspiration more than a system: use MOB. Their food is better presented than anyone's in the UK and their library is deep. If your problem is "I'm bored of what I cook" rather than "I don't know what this week costs or whether it hits my numbers", that's a content problem and they solve it.
On free apps like MUNCH and Samsung Food: free is genuinely free, and if paying nothing is the constraint, they will get you a plan. What they can't tell you is whether that plan hits your protein target, or what it will actually cost at the till — free apps work from estimates and generic nutrition data rather than tracked prices. Worth knowing what you're trading before you decide the £6.99 isn't worth it.
Where the real prices claim gets slippery
"Real supermarket prices" is used loosely across the category, so it's worth knowing what to check:
- Which stores, exactly? Basket-integration apps can only work with supermarkets that have online shopping APIs — which is why none of them cover Aldi or Lidl, the two cheapest chains in the UK. If your budget strategy is "shop at Aldi", that's a significant gap, and Mealia's own guide concedes the point.
- How fresh is the data? "Live" and "updated daily" are common claims and rarely evidenced. Ours are scraped and refreshed monthly, which we'd rather state plainly than dress up.
- Priced per what? An app can show a total basket price without ever telling you what a single serving of a meal costs. Cost per serving is the number that tells you whether a recipe is worth repeating.
For the record, ours: 3,300+ tracked product prices across Aldi, Tesco, Sainsbury's and Asda, refreshed monthly, with every recipe costed per serving. Dinners average £1.72 a serving across our library, with most meals falling between £1.10 and £2.40.
What a realistic budget actually looks like
Be sceptical of very low weekly figures. You will see "£25 a week" plans advertised, and they're technically achievable — porridge, beans, pasta, rice, repeated. What they cost you is variety, and most people abandon them inside a fortnight.
Our honest numbers, for a planned week with enough variety that you'd stick with it:
- One adult: about £45–50 a week
- Two adults: about £75–85 a week
- Two adults and a child: about £80–90 a week
Those are higher than the headline figures some apps advertise. We'd rather quote something you'll actually hit.
How to choose, in one paragraph
Ask what your real problem is. If it's *the chore of shopping*, pick a basket-builder. If it's *boredom*, pick a recipe app. If it's *money and nutrition at the same time* — you need the week to hit your protein target and land under a number at the till — that combination is the narrow gap the category has mostly left open, and it's the one we built Plan X Prep to fill.

Frequently asked questions
- Which UK meal planning apps use real supermarket prices?
- Mealia and Cherrypick use live prices via supermarket basket integration (Tesco, Asda, Sainsbury's; Mealia adds Morrisons). MUNCH claims live prices including Aldi and Lidl. Plan X Prep costs every recipe against 3,300+ scraped prices from Aldi, Tesco, Sainsbury's and Asda, refreshed monthly. MOB and Samsung Food have no price data.
- Is there a free budget meal planning app in the UK?
- Yes. MUNCH is free and covers Aldi, Lidl, Tesco and Sainsbury's. Cherrypick has a free tier with supermarket basket integration, plus optional paid tiers. Samsung Food is free but has no pricing or budget features at all.
- Which meal planning apps plan around macros, not just calories?
- Very few in the UK. Eat This Much builds plans to full macro targets but prices in US dollars against American groceries. Plan X Prep plans to your calorie and macro targets using the Mifflin-St Jeor formula and prices in GBP. MOB, Mealia, Cherrypick and MUNCH do not plan to macro targets.
- Why doesn't any app use Aldi prices for automatic basket filling?
- Aldi and Lidl don't offer online grocery shopping with the APIs that basket-integration apps rely on. That's why apps like Mealia and Cherrypick cover Tesco, Asda, Sainsbury's and Morrisons instead. Apps that quote Aldi prices, including Plan X Prep, give you a priced shopping list to take in-store rather than an automated basket.
- How much should a weekly food shop cost in the UK in 2026?
- For a planned week with real variety, roughly £45-50 for one adult, £75-85 for two adults, and £80-90 for two adults plus a child. Lower advertised figures such as £25 a week are achievable but rely on heavy repetition of cheap staples like porridge, beans, pasta and rice.
