Chowdown vs Lifesum: Free Macro Tracker Comparison 2026

TL;DR

• Lifesum has a polished interface and a big food database, but most useful features sit behind Premium (£39.99/year)
• Chowdown is fully free — AI photo scanning, barcode scanning, recipe tracking, unlimited history, no upsells
• Lifesum’s free tier restricts you to calorie tracking and basic logging; macros and meal plans require Premium
• If you want proper macro tracking without a subscription, Chowdown wins on both principle and features
• For casual calorie-only tracking with a nice UI, Lifesum’s free tier is workable — but it isn’t a macro tracker

Lifesum is one of those apps you see in the App Store top charts every year. Clean design, big marketing budget, “1 in 10 Europeans use it” kind of claims. And to be fair, the interface is nice. Onboarding is slick. It feels modern in a way most tracking apps don’t.

But once you start using it for actual macro tracking, the free tier shows its seams fast. Almost everything useful is locked behind Premium, and the things that aren’t locked feel deliberately limited to push you towards a subscription.

Here’s a head-to-head look at how Lifesum’s free tier stacks up against Chowdown, which doesn’t have a paid tier at all.

Free Tier: What You Actually Get

Lifesum Free

• Calorie tracking (no macro breakdown unless you upgrade)
• Basic food diary with limited customisation
• Limited food database (most items push you to Premium)
• No barcode scanning
• No recipe tracking
• No meal plans
• Ads between screens

Chowdown Free

• Full macro tracking (protein, carbs, fat, fibre)
• AI photo scanning of meals
• Barcode scanning for packaged foods
• Recipe and homemade meal tracking
• Unlimited history
• No ads, no upsells, no paywall prompts

The gap isn’t subtle. Lifesum’s free tier is a calorie counter with a nice UI. To track macros — the whole point of most people downloading a nutrition app — you need Premium.

Premium Pricing: What Lifesum Charges

Lifesum Premium runs around £39.99 per year, sometimes £9.99 per month if you don’t commit annually. That unlocks:

Feature	Free	Premium
Calorie tracking	✓	✓
Macro breakdown	✗	✓
Meal plans	✗	✓
Recipe suggestions	✗	✓
Fasting tracker	✗	✓
Advanced insights	✗	✓
Barcode scanning	Limited	✓

None of those Premium features are revolutionary. Macro tracking in particular shouldn’t be a paid feature in 2026 — it’s table stakes. Chowdown includes all of it for free and adds AI photo scanning on top, which Lifesum doesn’t offer at any tier.

Food Database and Accuracy

Lifesum’s Database

Lifesum’s food database is large but leans heavily on user-submitted entries, which means accuracy varies wildly. Finding the right “chicken breast” can mean scrolling past fifteen duplicates with different macro numbers. The official entries are generally accurate, but distinguishing them from the community-submitted ones isn’t always obvious.

Chowdown’s Database

Chowdown uses USDA data as its backbone for whole foods, with barcode lookups for packaged items. That means fewer duplicates and more reliable macro numbers for the foods you eat most. UK-specific products (Tesco, M&S, Sainsbury’s) are well-covered via barcode scanning.

Neither app is perfect — accuracy varies significantly depending on how apps source their food data, and every food tracker has quirks. But free Lifesum doesn’t give you macros at all, so database quality is moot if you can’t see the numbers you’re tracking.

AI Photo Scanning

This is where the comparison stops being close.

Lifesum

No AI photo scanning feature at any tier. You log every food manually or by barcode.

Chowdown

Snap your plate. Get a macro estimate back in seconds. Works for home-cooked meals, restaurant dishes, and anything without a barcode.

For home-cooked meals, restaurant dishes, and anything without a barcode, AI scanning is the difference between logging in ten seconds or abandoning the app. In 2026, it’s increasingly the baseline expectation — and Lifesum hasn’t shipped it. We’ve compared all the free AI food photo scanning apps available this year if you want to see how the landscape looks.

Barcode Scanning

Lifesum

Available in free tier but limited. You’ll hit paywalls on frequent use or on specific product categories.

Chowdown

Unlimited barcode scanning on the free tier. Scan every packaged food you eat. No limits.

For UK users, this matters — most of what’s in a Tesco trolley has a barcode, and Chowdown’s barcode scanning works without limits on any packaged food, saving real time on every log.

The Paywall Experience

If you’ve used Lifesum free for a week, you’ll know the vibe: pop-ups after almost every action nudging you towards Premium. It’s a model we’ve seen across the category — most “free” macro tracking apps aren’t really free once you dig into what’s actually gated.

• “Upgrade to unlock this feature”
• “Try Premium free for 7 days”
• “Unlock personalised meal plans with Premium”
• Constant Premium banners at the top of the diary

Chowdown doesn’t have a Premium tier, so there’s nothing to upgrade to. The app you open is the full app. No paywalls, no nudges, no “limited time offer” pop-ups.

Usability and Design

Both apps are genuinely well-designed. This is Lifesum’s real strength — it looks nice. Font choices, colour palette, animations, all polished.

Chowdown’s design is more functional. The focus is on speed — snap, log, move on. Less decorative, more efficient. If you’re tracking three meals a day, you want fewer taps, not prettier screens.

Neither is hard to use. Pick based on features, not looks.

Integrations and Ecosystem

Lifesum

• Apple Health and Google Fit integration
• Connects with Fitbit, Garmin
• Water intake tracking (free)

Chowdown

• Apple Health integration
• Weight tracking
• No wearable-specific integrations yet

If you live in the Fitbit or Garmin ecosystem and want deep integration, Lifesum’s Premium tier covers that. If you’re on Apple Health only, both apps are roughly equivalent.

Who Should Use Which

Lifesum Might Suit You If

• You’re already paying for Premium and like the meal plan content
• You don’t care about macros, just calories
• You prefer a lifestyle-oriented app over a tracking-focused one
• You’re heavily invested in a Garmin or Fitbit workflow

Chowdown Is Better If

• You want full macros without paying
• You want AI photo scanning as a core feature
• You’re tired of paywalls on basic features
• You want an app that stays free long-term without a surprise paid upgrade

The Real Cost Comparison Over 5 Years

Let’s put some numbers on it. If you stick with Lifesum Premium at £39.99 per year:

Period	Lifesum Premium	Chowdown
Year 1	£39.99	£0
Year 3	£119.97	£0
Year 5	£199.95	£0

Two hundred quid over five years for features Chowdown includes in the free tier. That’s the real decision.

The Bottom Line

Lifesum’s free tier isn’t really a macro tracker — it’s a calorie counter with a pretty UI and aggressive upsells. If you want to track macros properly, you either pay £40 a year for Premium or switch to an app that includes macros in the base experience.

Chowdown is that app. Free forever, macros included, AI scanning built in, no subscription wall. Give it a go and see how much app you can get without reaching for your card.
