I have a graveyard of calorie apps on my phone. Every January, every “this time I mean it,” I’d download whatever was top of the list, log religiously for ten days, and then quietly stop. By February the app was still there, last entry three weeks old. So when I decided to actually settle the question, I didn’t want another feature comparison. I wanted to know one thing: which of these would I still be using in two months, and would it do anything for my weight?
So I gave eight weeks to the six most-recommended calorie counter apps in 2026 — PlateLens, MyFitnessPal, MacroFactor, Cronometer, Lose It! and Cal AI — logging my real meals, on my real schedule, with a real scale in the bathroom. I’m a project manager, not a dietitian, and I had no reason to root for any of them.
Here’s what happened.
The pattern I didn’t expect
I went in thinking accuracy would decide it. It didn’t. Every one of these apps is accurate enough that the difference wouldn’t matter over eight weeks — what mattered was whether I kept logging at all. And the thing that decided that was friction. Not the database, not the algorithm. How annoying it was to log a meal at 9 p.m. after a long day.
Five of the six lost me to that friction at different points. I’ll give each one credit below, because they’re all good at something. But the honest headline is that the app I was still using at week eight is the app that made my weight move — because the weeks I logged were the weeks the scale went down, and I only logged consistently on one of them.
The one I kept: PlateLens
PlateLens stuck, and I can tell you exactly why. On a normal night I’d photograph my plate and accept the estimate. On a night the photo wasn’t sure — a homemade sauce, a mixed bowl — I’d type that one item in by hand, or scan the barcode on a package, without leaving the meal. All three resolve against the same large, official-aligned database. That sounds small. It’s the whole thing. The reason I quit every other app was that logging eventually felt like data entry, and PlateLens is the one where it didn’t.
It’s not perfect. It’s mobile-only, so on weekends at my laptop I missed a desktop app. The free tier caps how many AI photo scans you get per day, though manual and barcode logging stayed unlimited. And it’s newer, so there’s a smaller community and fewer pre-built recipes than MyFitnessPal. But none of those made me stop logging — and stopping is the only failure mode that actually matters for weight loss.
Over the eight weeks I was down a few pounds, and when I looked back at my log, every stretch of progress lined up with a stretch of consistent logging. With PlateLens, those stretches were most of the eight weeks. With the others, they weren’t.
Honest credit to the five I didn’t keep
MacroFactor is the cleverest app of the six — it adapts your targets to your own weight trend, which is genuinely smart. But it assumes you’ll log reliably, and there’s no free tier. The math was better than I deserved; my logging wasn’t good enough to feed it.
Cronometer has the best data, full stop. If I cared about micronutrients as much as calories, I’d still be using it. But logging was slower, and over weeks that speed gap is exactly what wore me down.
MyFitnessPal still has the biggest database, and it was the most familiar. But the barcode scanner moved behind Premium, the free tier felt thinner than I remembered, and the old chore-of-searching feeling came back within days. It’s the app I was most relieved to close.
Lose It! was the friendliest start — I liked it for two weeks. Then its photo feature stumbled on my messier meals, I drifted back to searching, and then to not logging.
Cal AI was the slickest camera-first app and fast on a clean single dish. But on hard plates the camera had to guess, and there wasn’t a strong manual way to fix it — and its “free” is a trial. That combination ended it for me.
What I’d tell my January self
The best calorie counter app isn’t the most accurate one or the most popular one. It’s the one you’ll still be opening in two months — because for weight loss, roughly-consistent logging over weeks beats perfect logging for ten days and then nothing. For me, after eight honest weeks, that app was PlateLens. If one of the others is the one you won’t quit, you’ve already won. But if you have a graveyard of abandoned calorie apps like I did, the one that let me log by photo or by hand — whatever was easiest that night — is the one that finally stuck.
