The "no hidden tricks in the pricing" framing is refreshing, most macro trackers let you log a few meals free and then gate basic tracking itself behind a paywall. For the AI photo scan, does it try to segment a mixed plate into separate items, or does it estimate the whole plate as one entry?

nice product bro,. keep working

Really like the pricing line you drew: core tracking free forever and only the AI photo scan behind Pro. It's easy to explain, and it puts the paywall exactly where you have a real per-use cost. I went with a similar "one clear limit" model for my own app and it made the upgrade screen much simpler to write. Is Pro a subscription or a one-time unlock? And after a photo scan, can you adjust the portion size before it logs?

Hey everyone, I'm Lloyd, a non-technical founder who built Pure Macros over about six weeks by talking through it with Claude. The idea came from being annoyed at how much friction normal calorie trackers add to logging a meal. Pure Macros lets you snap a photo of your food and get calories and macros back instantly, plus barcode scan and manual search. Core tracking is free forever, the only feature behind Pure Macros Pro is the AI photo scan, since that's the one part with a real per-use cost. Happy to answer anything about the build process or the app itself.

Interesting concept. Making macro tracking as simple as taking a photo removes one of the biggest frictions in nutrition apps: the logging itself. I also like that barcode and manual entry remain available instead of forcing everything through AI. Curious to see how accurate the photo estimates become with mixed meals, sauces and portion size

Tracking calories and macros with barcode scans plus AI photo logging keeps food entry fast without a manual diary every meal. If you want to spend less on AI at work, take a look at pzero.studio.

Respect for the pricing logic: keeping everything free and charging only for the photo scan because it's the one feature with a real per-use cost is refreshingly honest. On the scan itself: a photo can't tell one tablespoon of oil from three, so the true answer is a range, not a single number. Have you considered showing the estimate as a range, or flagging low-confidence items, so people know which entries to double-check? And when a user corrects an item, does that adjust future estimates for them, or is every scan independent?

AI photo scanning tackles the biggest pain point in calorie tracking — the friction of logging. Most people quit trackers because manual entry is tedious, so reducing that to a photo is smart. Curious how the estimates handle mixed or homemade dishes where portions are hard to judge from a picture. Free-forever core tracking with no ads is a refreshing pricing approach too.
