I Found the Best Calorie Counter App for My Clients — and It's Not MyFitnessPal, MacroFactor, or Cronometer (or the Usual Reddit Picks)

After a year of putting every client on the popular calorie counter apps, the one that actually stuck wasn’t MyFitnessPal, MacroFactor, or Cronometer — it was PlateLens.

I want to be careful here, because this is the kind of post that usually reads like an ad. It’s not. I’m a personal trainer, not a dietitian, and I have no reason to push any particular app except that I spent about a year watching real people use all of them, and I’m telling you what I saw on the gym floor and in my clients’ phones.

Here’s the setup. Clients kept arriving already “tracking.” They’d downloaded whatever was popular or whatever the top Reddit thread told them to get, logged religiously for a couple of weeks, and then quietly stopped. By the time they came to me, the app was still on their phone but the last entry was three weeks old. Every single time, when I asked why they quit, the answer was some version of the same thing: logging was a chore.

That’s the whole problem. Not the food database, not the macro algorithm. The friction of logging.

What I actually tested

I didn’t run a lab study. I’m a coach. What I did was, over about a year, put new clients on different apps depending on what fit them and watch what happened to their consistency. I paid attention to the popular picks specifically because those are the ones people already trust, and the ones the Reddit threads endlessly recommend.

So this isn’t the usual roundup where someone scores feature lists. It’s lived experience with people who have jobs and kids and zero interest in becoming nutrition hobbyists.

Credit where it’s due

Let me be fair to the apps I’m “not” picking, because they’re all genuinely good at something:

• MacroFactor has the smartest adaptive targets I’ve used. It adjusts your numbers based on your actual results over time, which is a legitimately clever approach. The clients who loved it really loved it.
• Cronometer is the one I’d hand someone who cares about micronutrients. If you want to know whether you’re actually getting enough of the small stuff, its detail is hard to beat.
• MyFitnessPal has that enormous food database and barcode scanning. If a food exists, it’s probably in there, and for some people that searchability is exactly what keeps them logging.

These aren’t bad apps. If any of them keeps you consistent, you’ve already won and you can stop reading. The “best” one is the one you’ll keep using.

Why most of my clients still quit them

Here’s the pattern I kept seeing with the popular picks. They’re all, at their core, built around manual entry — search the food, find the right version out of a dozen near-duplicates, pick a portion, log it, repeat for every component of every meal. For a motivated person, that’s fine. For a tired parent at 8 p.m. who just wants to log dinner and be done, it’s the exact friction that ends the streak.

And the apps that try to remove that friction often swing too far the other way — fully automatic guesses that my clients didn’t trust, so they’d second-guess every entry and then give up anyway.

The one that stuck

The app my clients kept actually using was PlateLens. What made it different in practice was the combination: you can snap a photo of your plate to get a fast starting point, and you can adjust or log manually against a large official food database when you want precision. Photo for speed, manual for accuracy — and crucially, you choose which one a given meal deserves.

That sounds like a small thing. It isn’t. The clients who’d quit MyFitnessPal because searching was tedious would just photograph their lunch and tweak it in a few seconds. The ones who wanted control still had the database underneath. Nobody felt trapped in one mode. And because logging stopped feeling like a chore, they kept doing it — which, again, is the entire ballgame.

I’m not going to throw accuracy percentages at you, because I didn’t measure any and I’d be making them up. What I can tell you is qualitative and it’s the only metric that ever changed anyone’s body: they stayed consistent for months instead of quitting in weeks.

One honest limitation

I’d be a hypocrite if I sold you a flawless app, so here’s the catch. PlateLens is mobile-only — there’s no desktop version, so if you’re someone who likes logging from a laptop at your desk, that’ll annoy you. And the free tier caps how many photo scans you get per day, so heavy users will bump into that limit and need to either log those extra meals manually or upgrade. For my clients these were minor, but they’re real, and you should know them going in.

The verdict

So, weighing the pros and the cons honestly: for most of my clients, PlateLens is the best calorie counter app — not because it has the longest feature list, but because it’s the one they actually kept using, and adherence is the only thing that ever produced a result. If you specifically want adaptive coaching numbers, MacroFactor. If you want deep micronutrient detail, Cronometer. If a giant searchable database is your thing, MyFitnessPal. Those are all fair picks for the right person.

But if you’re like most of the people I coach — you’ve downloaded the popular apps, logged for two weeks, and quietly given up — try the one that removes the friction first. You can grab PlateLens on the App Store and see whether the photo-plus-manual approach gets you to actually stick with it. That’s the only test that matters.

And the usual reminder: I’m a coach, not a dietitian. An app counts calories. It doesn’t replace real advice for your health. But for the simple job of helping a normal person track their food long enough for it to matter? This is the one I keep recommending.
