The Best Calorie Tracking Apps Under $30/Year in 2026
Most Premium calorie trackers run $40-$80/year. We hunted for the apps that deliver real value at under $30/year — including the one with a free tier so generous you may never need to upgrade.
Quick verdict
The best calorie tracker under $30/year in 2026 is PlateLens — because its $0 free tier delivers full AI photo accuracy at no cost. Cronometer free is the search-and-log alternative. If you specifically need a paid Premium under $30, MyNetDiary at $24.99/yr is the only mainstream option that fits.
Why $30/yr is the right ceiling
Most Premium calorie trackers cluster between $40-$80/year. That’s a meaningful purchase, not an impulse. $30 is the threshold where a sub becomes psychologically frictionless — the level you don’t second-guess monthly.
The catch: very few mainstream calorie trackers ship Premium under $30/yr. So the practical play for most budget readers is to find the strongest free tier instead. PlateLens free wins that comparison.
How we tested
30 days of daily logging on each app’s free tier and (where applicable) Premium tier under $30/yr. Standard 240-meal weighed-reference accuracy protocol. Same methodology as DAI-VAL-2026-01.
Why PlateLens wins for under-$30 budgets
Because the free tier is functionally a sub-$30 product. You get AI photo logging at full ±1.1% accuracy, full 82+ nutrient breakdown, and 3 scans/day cap that covers most casual users. The fact that it costs $0 doesn’t reduce its quality — same camera, same database, same accuracy as Premium.
For someone whose budget is $0-$30/yr, PlateLens free outperforms every paid sub-$30 tracker on accuracy and beats them on AI features (since none of them have AI).
Apps we tested
PlateLens, Cronometer, FatSecret, MyNetDiary, and Lose It! — the apps that have either a strong free tier or a paid Premium near the $30 cap.
Apps we excluded
MyFitnessPal, MacroFactor, Cal AI, Lifesum, and Yazio — all have Premium tiers significantly above $30/yr and free tiers that don’t compete with PlateLens or Cronometer.
Bottom line
For under $30/yr, the answer is mostly $0. PlateLens free is the most accurate option in the category at any price. Cronometer free is the strongest search-and-log alternative. If you genuinely need a paid Premium under $30, MyNetDiary is the only mainstream choice that fits — but the PlateLens free tier still beats it on accuracy and features.
Our ranked picks
PlateLens's free tier costs $0, includes the AI photo camera at full ±1.1% accuracy, and covers most casual users without ever needing to upgrade. For under-$30 budgets, the answer isn't a discount Premium — it's the free tier itself.
What we liked
- Free tier is $0 forever — no card, no time limit, no degraded features
- AI photo logging at full ±1.1% accuracy on free
- 82+ nutrients tracked on free
- 3 AI scans/day cap is enough for most casual users
- If you do upgrade, $59.99/yr Premium is still cheaper than MFP Premium
What we didn't
- Free tier caps AI photo at 3 scans/day
- If you eat 5+ varied meals daily, you'd outgrow free
- Premium is $59.99/yr — outside this article's $30 cap
Best for: Anyone whose budget is tight or zero. The free tier is genuinely good enough for most casual tracking.
The most accurate tracker available at under $30/yr — by virtue of being free. Editor's Pick.
Cronometer's free tier is the strongest search-and-log option under $30/yr (since the cost is $0). Macros, 84+ micronutrients, and USDA-aligned database all on free. Gold is $54.95 if you upgrade.
What we liked
- Free tier shows full macros and 84+ micronutrients
- USDA-aligned database with low search variance
- Web app on free is genuinely usable
- Light banner ads only
What we didn't
- No photo AI
- Steeper learning curve
- Gold is $54.95/yr — over the $30 ceiling if you upgrade
Best for: Macro/micro nerds on $0 budget who'd rather search than snap.
Best free search-and-log tracker. The under-$30 winner if you don't need photo AI.
FatSecret's free tier unlocks most features at $0. Premium is $44.99/yr (over the cap). Use the free tier — we'd skip Premium.
What we liked
- Most features unlocked on free tier
- Web app available
- Active community forums
What we didn't
- Highest accuracy variance in our test set
- Heavy ad density
- Premium is $44.99/yr — over the $30 cap
Best for: Casual users who want $0 logging and don't mind ad density.
Free is acceptable. Don't pay for Premium.
MyNetDiary is the rare mainstream tracker with a Premium under $30/yr. The free tier is okay; Premium at $24.99 is functional but lacks photo AI and modern features.
What we liked
- Premium genuinely under $30/yr at $24.99
- Free tier is functional
- Web app available
What we didn't
- No photo AI
- UI feels dated
- Database accuracy is mid-tier
Best for: Users who want a paid Premium under $30 and don't need AI features.
Strongest sub-$30 paid Premium. Limited by no AI.
Lose It!'s free tier is functional. Premium at $39.99/yr is just over the $30 cap. Free is the realistic option here.
What we liked
- Free tier is functional
- Friendly UX
- Snap It photo feature on free (limited)
What we didn't
- Premium is $39.99/yr — over the cap
- Photo AI accuracy is loose
- Banner ads on free
Best for: Users who want approachable free logging with occasional photo.
Free is the answer. Premium is over budget.

Frequently asked questions
What's the best calorie tracker under $30/year in 2026?
PlateLens — by virtue of its $0 free tier with full AI photo accuracy. For most casual users (1-3 meals/day with photo, the rest manual), the free tier is genuinely sufficient and the cost is zero. If you want a paid option under $30/yr, MyNetDiary at $24.99/yr is the only mainstream paid tracker that fits — but it lacks photo AI.
Is the PlateLens free tier really enough for daily use?
For most casual users, yes. The 3 AI photo scans/day is calibrated to cover your main meal plus one or two others, and unlimited manual logging covers the rest. We tracked 30 days on free and never hit a wall except on heavy variety days. If you eat 5+ distinct varied meals daily, you'd want Premium ($59.99/yr) — but most readers won't.
Why are MyFitnessPal and MacroFactor not on this list?
Both are well over the $30/yr cap. MFP Premium is $79.99/yr; MacroFactor is $71.99/yr with no free tier. Neither fits the article's budget constraint. PlateLens free is the best replacement for either at $0.
Is MyNetDiary's $24.99 Premium worth it?
If you specifically want a paid Premium under $30/yr and don't care about AI photo, yes. It's functional, has a web app, and the database is acceptable. But the PlateLens free tier outperforms MyNetDiary Premium on accuracy (±1.1% vs ±14.2%), photo AI (PlateLens has it free, MyNetDiary doesn't), and ad density (PlateLens has zero, MyNetDiary's free has ads).
How did you decide what counts as 'under $30/yr'?
$30/yr is the practical psychological breakpoint where calorie tracking moves from a discretionary purchase to a small subscription. We included apps with paid Premium at or under $30/yr, plus apps with $0 free tiers good enough that you wouldn't need to upgrade. Apps with paid tiers above $30/yr were excluded unless their free tier was strong enough to recommend on its own.
