Corvex vs Lifesum

Lifesum is a programme, not just a tracker

Lifesum describes itself as a healthy eating platform, and its App Store listing bears that out: photo, voice, text and barcode logging, plus named diet programmes including keto, paleo and high-protein, a large recipe library with meal plans and grocery lists, water and body-measurement tracking, and a Life Score that grades eating habits, hydration and activity together.

That is a coherent product with a clear customer. If your problem is not "I do not know how many calories that was" but "I do not know what to cook on Thursday", a tracker will not help you and a meal plan might. Corvex has no plans, no recipes and no score, and adding them would make it a different product.

Why people look for an alternative anyway

The searches tend to come from a few specific frictions rather than a general complaint.

• The surface area. Plans, recipes, scores and programmes are a lot of app to walk past when all you wanted was to log lunch.
• The paywall sits close to the good parts. Lifesum lists Premium in-app purchases on the US App Store at US$7.49 monthly, US$14.99 for three months and US$49.99 annually, with other regional tiers ranging up to US$119.99.
• Scores can read as judgement. A single number grading your week is motivating for some people and demoralising for others, and you rarely know which you are until you have lived with it.
• Plan fatigue. Diet programmes work while you follow them, and the follow-through is the hard part.
• You already eat well and just want the arithmetic.

Where Lifesum is genuinely better

These are not token concessions. If any of them describes you, Lifesum is the better purchase.

• Meal plans and named diets. Real structure for people who want the decision made for them.
• Recipes with grocery lists. Corvex has none of this and no plans to add it.
• Life Score. One glanceable read on the week, if that framing motivates you.
• Multimodal logging including photo scanning, which Corvex does not offer.
• Platform reach and integrations — Android, wearables, and syncs Corvex has not built.
• Water and body measurements, tracked in-app.

Where Corvex is different

Corvex is deliberately narrow. It tracks what you ate, what that adds up to, and what your weight is doing — and then gets out of the way.

• One log sheet, one tap from every screen, with four ways in: plain-words description, barcode, recents, or manual macros.
• No ads on any tier. Premium adds longer history, advanced charts and the full sticker library.
• Weigh-ins as a trend line with start, current and target always visible.
• Protein, carbs and fat as a share of the day with grams remaining, and fibre tracked alongside without being folded into the calorie maths.
• Share stickers for streaks and progress, designed for Stories — the only social thing in the app, and it points outward.
• No score, no grade, no plan telling you what Thursday looks like.

Protein without the programme

One reason people adopt a diet programme is protein: they have heard it matters and want a plan that handles it. You can get the same benefit from a target and a tracker.

The Acceptable Macronutrient Distribution Range puts protein at 10–35% of energy for adults, with an RDA of 0.8 g per kg of body weight as the floor rather than the goal. Set a number inside that range, watch grams remaining each day, and you have the useful part of a high-protein plan without subscribing to one. That is the whole of what Corvex offers here, and for a lot of people it is enough.

So which should you pick?

Pick Lifesum if you want recipes, meal plans and a structured diet to follow, if photo logging matters, or if you are on Android.

Pick Corvex if you know how you want to eat and want a log that stays out of your way, if a weekly grade would do you more harm than good, and if you want an ad-free daily view of calories, macros and weight in one place.
