A budget meal planning app is one that builds your weekly meals around a spending limit and shows roughly what the shop will 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 last checked in September 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) | Unclear — shows calories and protein; we found no macro-target setting | 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 — macros on every recipe, high-protein options; no macro targets found | £6.99/month |
| Samsung Food | No budget features found; says it links to some UK online shops | Partly — free daily macro targets; goal-tailored week plans (2 free, then Food+) | Free; Food+ £6.99/month |
| Eat This Much | US prices only — not useful in the UK | Yes | $5/month billed yearly ($14.99 monthly) |
| Plan X Prep | Yes — Aldi first; Tesco, Sainsbury's, Asda fill the gaps | Yes | From £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, as far as we can find, they can't; nutrition targets aren't what they're built 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 one of the biggest UK names, MOB, sits in a third category: excellent recipes, no price layer whatsoever. Some of its own users have asked 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. We can't match a one-tap trolley at Tesco or Asda, and we don't pretend to — Plan X Prep gives you a priced list, grouped by supermarket section, 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 beautifully presented 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 we couldn't find in either is both halves at once. MUNCH says it plans to your budget with live prices, but we found no way to set macro targets. Samsung Food has free macro targets, but we found no budget features. 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 checked monthly, though not every price is updated every month — 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: 2,000+ real product prices from Aldi, Tesco, Sainsbury's and Asda, checked monthly (Aldi first; the others fill the gaps), with every recipe costed per serving. Dinners average £1.85 a serving across our library (as of Sept 2026), with most main meals falling between £1.10 and £2.50.
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.
Our honest number, for a planned week with real variety (16 or more different recipes): a balanced solo week at around 2,000 kcal typically comes to £50–55 at Aldi prices. That's the fresh shop, not cupboard staples.
We're not quoting couple or family figures until we've priced real weeks for them.
That's higher than the headline figures some apps advertise. We'd rather quote a number we've actually measured.
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 want the week built around your protein target and your budget — 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 from 2,000+ real product prices, checked monthly: Aldi first, with Tesco, Sainsbury's and Asda filling the gaps. MOB has no price data. Samsung Food says it can send lists to some UK online shops, but we found no budget features.
- Is there a free budget meal planning app in the UK?
- Yes. MUNCH is free and says it has live prices from Aldi, Lidl, Tesco and Sainsbury's. Cherrypick has a free tier with supermarket basket integration, plus optional paid tiers. Samsung Food has a free version (Food+ is paid), but we found no budget features.
- 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. Samsung Food lets you set daily nutrition targets for free and offers goal-tailored week plans (two free, then paid Food+), but we found no budget features. Plan X Prep estimates your calories with the Mifflin-St Jeor equation, builds your plan around your calorie and macro targets, and prices it in GBP. We found no sign that MOB, Mealia, Cherrypick or MUNCH plan to personal 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 Mealia and Cherrypick cover Tesco, Asda and Sainsbury's instead (Mealia adds Morrisons). 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?
- On our measurements, a balanced solo week at around 2,000 kcal with real variety typically comes to £50–55 at Aldi prices (fresh food, not cupboard staples). We're not quoting couple or family figures until we've priced real weeks. Lower advertised figures such as £25 a week are achievable but rely on heavy repetition of cheap staples like porridge, beans, pasta and rice.
