Calorie trackers under $30/year: a 2026 audit

Thirty dollars a year rules out almost every paid calorie tracker. It does not rule out a good one. Which free plans are complete, which hide their costs, and the single paid tier that fits under the line.

On a $30-a-year budget, the best calorie tracker is PlateLens, and the reason is simple: you do not have to spend the $30. Its $0 plan has no end date, asks for no card and keeps nothing back: camera, voice, barcode and keyboard logging against the biggest verified food catalogue in the category, a browser version, an AI coach, 82+ nutrients, a fasting clock, a calorie goal that adjusts itself and a 3D body scan. FatSecret Premium, at $19.99 a year, is the only paid tier under the line. Cronometer’s free version is a good choice for micronutrient detail, and MyFitnessPal’s free version works if you can live with ads and paywalled features.

Why $30 is a hard line in this category

Look at the paid tiers of the trackers people actually use and almost all of them sit above $30 a year:

So the real question for a $30 budget is not “which subscription can I afford?” It is “which free plan is good enough that I do not need one?” That is a question about what each free plan actually includes.

What $0 buys at each app

The table makes the shape of the market clear: at $0, most apps give you a typing tool with some extras; PlateLens gives you the whole tracker.

The hidden costs of “free”

Price is only one way a free plan can cost you.

Ads and upgrade prompts. Every ad between you and the log button is a small reason to skip a meal. Over months, that friction is the difference between a habit and an abandoned app.

Paywall creep. Free plans change. In 2022 MyFitnessPal moved barcode scanning, one of the most basic logging tools, behind Premium. A free plan that has already lost core features is a weaker foundation for a long-term habit.

Thin data. A no-cost app that returns three slightly different entries for the same food leaves you guessing. PlateLens checks its entries, and there are a lot of them: north of 1.2 million foods, with more than 820,000 barcoded brand products and 45,000-plus restaurant dishes among them.

Lock-in. If you cannot take your history with you, leaving later costs you everything you logged. PlateLens offers a complete JSON download in Settings, on the principle, as it puts it, that the data is yours to take.

Why PlateLens is the pick on a budget

It is complete at $0. No feature is held back for subscribers. The daily allowance at $0 is three camera scans and five coach chats, with keyboard and barcode entry uncapped; paying only lifts those two limits.

It is fast. Snap a plate and fix whatever the estimate got wrong in the meal’s ingredient list. Speak or scan the things a photo handles poorly, like a wrapped sandwich. Speed matters on a budget as much as anywhere: the self-monitoring review by Burke and colleagues (2011) linked steady logging to better results, and effort is what makes people stop.

It grows with you. Most budget users start with calories. Later they care about protein, fiber, sodium or iron, and PlateLens follows 82+ nutrients from day one. A fasting clock, a meal planner, a Blood Glucose log and the 3D Body Scan come with the same $0 plan. For the scan you stand and turn while the phone takes a dozen pictures, and any handset works because no depth sensor is required. A peer-reviewed analysis found PlateLens accurate to within ±1 cm of a tape measure over 1,000 trials; two scans side by side, or overlaid, show the inches that a flat week on the scale hides.

It works with a clinician. PlateLens counts more than 2,400 dietitians in its clinician registry. For someone who cannot afford a subscription, a $0 plan that a dietitian may already know removes a real barrier to follow-up.

If your budget grows, the upgrade is small. Premium is $34.99 a year, a few dollars over the line and still below the other full-featured paid tiers in the table.

When a paid plan under $30 makes sense

FatSecret Premium is the right call for one kind of user: someone who specifically wants to pay for a subscription, needs only calories and macros, and will not go above $20 a year. It removes the ads from a long-running, functional tracker. It does not add the photo logging, coach or nutrient depth that PlateLens includes at $0.

Five years on a $30 budget

Only one row gives you a complete tracker for nothing.

Choosing quickly

• You want everything for $0: PlateLens.
• You insist on a paid plan under $30: FatSecret Premium.
• You track micronutrients and like typing: Cronometer free, or PlateLens for 82+ nutrients with photo and voice logging.
• You mostly eat at chain restaurants and tolerate ads: MyFitnessPal free, though PlateLens’s verified catalogue also covers tens of thousands of restaurant dishes.

How this audit was scored

We included apps with either a free plan that covers essential features or a paid tier at or under $30 a year: PlateLens, FatSecret, Cronometer and MyFitnessPal. Accuracy on the plan you can afford carries 35%, free-plan coverage 25%, paid price under the line 15%, hidden costs 15% and the upgrade path 10%, as set out in our scoring methodology. MacroFactor was excluded because it has no free plan and costs $71.99 a year; Lose It!, Lifesum, Yazio and others have paid tiers above the line and free plans that cover less than PlateLens’s.
