Cal AI alternatives: an honest comparison
One fact reframes this search: since March 2026, Cal AI belongs to MyFitnessPal. So the most recommended alternative on the internet is now owned by the app you were comparing it against. The real choices are a big database app with photo logging behind a subscription, a precision tracker for people who read labels, or a small photo-only app with its own subscription. This page says which is which, including where ours falls short.
Disclosure
We publish Calso, one of the four apps in the table below. Everything about the other three is taken from their own App Store listings and websites, read on 12 September 2026, and linked at the end. Prices on the App Store change and are shown per offer, so check the number on your own screen.
What are you actually replacing?
Cal AI is a photo-first calorie tracker built by two teenagers that reached more than 15 million downloads and over $30 million in annual revenue in under two years, according to TechCrunch's report of the acquisition. MyFitnessPal announced the purchase on 2 March 2026, the deal having closed the previous December, and kept Cal AI running as a standalone app.
On accuracy, the most useful number comes from Cal AI itself. Its website states that the app is "about 80% accurate" and that no food tracking app is perfect. That is an honest figure, and it matches the research: across 52 studies of photo-based dietary assessment, average calorie errors ran from under 1% on single foods to 38.3% on mixed plates. We went through that evidence in how accurate photo calorie counters are. No app in this category beats that limit, including ours, so accuracy is not the axis to choose on. Price, logging paths and data handling are.
The comparison, as the listings read on 12 September 2026
| App | Cost | App Store rating | Photo logging | Barcode and food database |
|---|---|---|---|---|
| Cal AI | Free download, Unlimited tiers $2.99 to $29.99 | 4.8, 362K ratings | Yes, the core feature | Yes, plus voice logging |
| MyFitnessPal | Free tier, Premium $9.99 or $19.99 monthly, $49.99 or $79.99 yearly | 4.7, 2.4M ratings | Yes, in Premium | Yes, the largest of the four |
| Cronometer | Free tier, Gold $10.99 monthly or $59.99 yearly | 4.8, 98K ratings | Yes, in Gold | Yes, curated, with micronutrients |
| Calso | Calso Pro subscription, monthly or yearly, price not published yet | Not published yet | Yes, the only way to log | No |
One detail worth noticing in that first row: Cal AI's listing carries five different Unlimited prices, from $2.99 to $29.99, plus a $0.99 streak restore. That is a vendor testing its pricing, which is legal and common, and it means a review quoting one annual figure is quoting the offer that reviewer happened to see.
When Cal AI is still the better choice
Three honest cases, and they are not edge cases:
- You log in more than one way. Barcodes, voice descriptions, custom recipes and manual entries all work there. Calso has none of them.
- You are on Android. Cal AI ships on both platforms. Calso is iOS only.
- You want a track record. 362,000 ratings and a MyFitnessPal database behind it is a different kind of reassurance from a new app with no reviews.
When a photo-only app is enough
If your habit is simply to photograph what you eat and watch the daily total, most of what a database app charges for is features you never open. In that case the questions worth asking are narrow:
- What does the photo feature cost once any trial ends, per month and per year?
- Can you delete the account and every photo yourself, without writing to support?
- Does the app tell you what its numbers are worth, or sell you certainty it cannot have?
Calso's answers: it needs a Calso Pro subscription, monthly or yearly, and because it is not published yet we cannot quote a price here; the app shows it before you pay. Deletion is one tap from the Profile tab. And we say the estimates will sometimes be substantially wrong. What it does with your photos, who receives them and how long they are kept is set out in the Privacy Policy rather than implied.
Where Calso falls short
This is the part most comparison pages leave out, so here it is in plain terms. Calso is the narrowest app on this page.
- Not on the App Store yet, so you cannot install it today.
- No free tier. Logging a meal needs a Calso Pro subscription, where MyFitnessPal and Cronometer both have free tiers.
- Photos only. No barcode scanner, no food search, no manual entry.
- No meal editing. If the model gets a meal wrong, you cannot correct it. You can log a meal or delete the whole account, nothing in between.
- iOS only, and it needs sign-in with Apple or Google.
- No micronutrients, no water tracking, no exercise import, no social feed.
If two of those matter to you, one of the other three apps is the better answer, and we would rather you knew now than after a week of logging.
FAQ
Is Cal AI free?
The download is free. The US App Store listing on 12 September 2026 shows paid Unlimited tiers at $2.99, $5.99, $9.99, $19.99 and $29.99, plus a Streak Restore item at $0.99, and the Cal AI website offers a three-day free trial. Which price you are shown depends on the offer you land on, so check the figure on your own screen before subscribing.
Who owns Cal AI now?
MyFitnessPal. The acquisition was announced on 2 March 2026, after the deal closed in December 2025, and Cal AI continues to run as a standalone app with its team retained. If you are leaving Cal AI to get away from MyFitnessPal, switching to MyFitnessPal is not an escape.
How accurate is Cal AI?
Cal AI's own website states that it is about 80% accurate and that no food tracking app is perfect. That is consistent with the published research on photo-based estimation, where average errors across 52 studies ran from under 1% on single foods to 38% on mixed plates. Treat any vendor claim above 90% with suspicion unless it says what it was measured against.
What is the best free Cal AI alternative?
It depends on what you need free. Cronometer and MyFitnessPal both have free tiers with large food databases and barcode scanning, but photo logging sits in their paid tiers. Calso has no free tier: it only does photos, logging needs a Calso Pro subscription, and it is not on the App Store yet.
Can I switch app and keep my history?
Usually not in any useful form. These apps do not import each other's meal logs, so a switch means starting the history again. If the history matters to you, export or screenshot the weekly totals before you delete the old account.
Do I need a subscription to count calories at all?
No. A free tier plus a set of portion habits covers most of it, and a scale for the calorie-dense foods covers the rest. See counting calories without a food scale.
Three things to take away
- Cal AI and MyFitnessPal are the same company since March 2026, which removes most of the point of switching between them.
- Accuracy is not the deciding factor. Cal AI says about 80%, the research says 1% to 38% depending on the food, and no app in this category escapes that.
- Choose on cost, logging paths and data handling. If you only ever photograph meals, compare what the photo feature costs you, not the length of the feature list.
Calso, if the narrow version is what you want
Photograph your plate, get calories and macros against targets built from your body and your goal. Sold as a Calso Pro subscription through the App Store, with one tap to erase everything. The home page lists what it does and what it does not.
