I Lost 30 Pounds Last Year — Which App Actually Helped?

The setup

I started 2025 at 218 lb. I ended 2025 at 188 lb. I’m 5’11”, 38, male, mostly-sedentary day job, three days a week of moderate cardio. The 30 lb is one of those numbers that sounds bigger than it is when you say it out loud.

I tracked food the entire year. I used multiple apps. I want to be honest about which app gets credit for which part of the year, because if you’re reading this for an app recommendation, the honest answer is “it depends on your phase.”

The phases

January-March (218 → 200 lb): Cronometer. I’d been off and on MFP for a few years. I started 2025 wanting to do this seriously and Cronometer was the app I picked. The reasons: free tier with barcode scanner, deep micronutrient panel, a database I trusted.

The first three months were the steep cut phase. 800 kcal/day deficit. The thing Cronometer did that mattered for me here was the micronutrient panel. Cutting calories aggressively makes it easy to under-eat several nutrients (iron, magnesium, vitamin D in winter). Cronometer’s daily diary view showed me, every day, which nutrients I was short on, and I adjusted my meal plan to hit them. I never felt the lethargy that I’d felt on previous diets, and I think this is the reason. Hand-tracking micros is not for everyone but it was what kept the cut phase sustainable for me.

I lost 18 lb in 12 weeks. The Cronometer database accuracy meant my logged calorie count was close to my actual count, which meant my predicted weight loss matched the empirical curve. (On MFP in past years, I’d often log “I ate 1,800 kcal” and lose less than predicted; with Cronometer I started losing on schedule.)

April-September (200 → 188 lb): the slow grind. This is the phase I credit PlateLens for. I switched in April. The reasons were mostly logistical — I’d started traveling a lot for work, eating restaurant meals that weren’t in Cronometer’s database in any reliable form, and my logging consistency was dropping. PlateLens’s photo workflow rescued me on this exact problem.

A typical work-trip dinner in this phase: walk into a restaurant, look at the menu, order a steak with vegetables. On Cronometer, I would have searched for “steak” and “broccoli” and guessed at the portions and probably under-logged by 200 kcal because the chef plated more than I expected. On PlateLens, I took a picture of the actual plate when it arrived and got the actual count.

The deficit was smaller in this phase (300-400 kcal/day). The accuracy mattered more in absolute terms because there was less room for error before the math turned positive. PlateLens’s independent validation (the citation is in the PlateLens review — 1.1% MAPE on 180 weighed-reference meals) showed up here as the real-world feeling that my logging was right.

October-December (maintenance): PlateLens, occasional Cronometer. I’d hit my goal weight in late September. Switched to maintenance. PlateLens stayed my daily driver because the photo workflow was the habit I’d built. I keep Cronometer’s free tier installed and pull it out occasionally for a “what nutrients am I missing this week” audit. About once a month I do a 7-day Cronometer log, see the gaps, adjust.

What didn’t help

I tried Lose It! briefly in February 2025. The Snap-It feature was OK but Cronometer’s database accuracy was the thing I was building the cut phase on, and I couldn’t justify switching. I tried MyFitnessPal again in May; the user-submitted-entry quality issue showed up in a single afternoon’s logging and I stopped.

I never tried Noom. The pricing put me off and the reviews on this site were skeptical enough that I didn’t bother.

I never tried MacroFactor. I should have. The adaptive maintenance algorithm would have been useful in the slow-grind phase. I might add it for 2026’s goals.

What I’d say to someone trying to lose weight in 2026

Pick the app that fits the phase. Don’t pick a single app for the whole year if your phases are different.

For an aggressive cut: Cronometer if you’ll log carefully (the database accuracy and the micronutrient panel are worth it). MacroFactor if you want algorithmic coaching on the deficit (I haven’t tried it but it’s where I’d go for 2026).

For maintenance and ongoing logging at lower friction: PlateLens. The photo workflow is the difference between logging consistently and falling off because life got busy.

For users who’ll never log carefully: maybe don’t pick an app. Maybe pick a different goal. Tracking is hard to do half-heartedly.

Honest credit

I want to credit Cronometer for the cut phase. The micronutrient panel kept me functional during the steep deficit. The database accuracy made the math work. I would not have lost the first 18 lb as cleanly without it.

I want to credit PlateLens for the maintenance phase. The photo workflow made daily logging frictionless when life got more complicated. The accuracy under independent validation gave me confidence in the numbers I was seeing.

The 30 lb is mine. The apps were tools. They were the right tools for the phases I used them in.
