yqiang··on Ask HN: What are you working on? (September 2026)
I’m building FitBee, a fast, ad-free, no-nonsense calorie and macro tracker for iPhone, iPad, and Apple Watch. The app is built with Swift and SwiftUI, with a Python backend. https://fitbee.app
yqiang··on Ask HN: Calorie Trackers
Shameless plug, but if you're on iOS, I've been working on https://fitbee.app. It's similar to MFP in many ways, but has significantly fewer paper cuts and no ads. Would love your feedback if you end up giving it a try!

I’m building FitBee, a fast, ad-free, and no-nonsense calorie and macro tracker for iPhone, iPad, and Apple Watch: https://apps.apple.com/us/app/fitbee-calorie-macro-counter/i...

Built in Swift, SwiftUI for the iOS app and Python for the backend.

yqiang··on Ask HN: What Are You Working On? (April 2026)
I'm working on a calorie & macro tracker called FitBee [1]. Tracking my food has been tremendously helpful in terms of improving my health, but it's always been a PITA. The focus of FitBee is food quality & speed. Tracking your food is something you have to do multiple times a day, so I tried to make it as frictionless as possible. The app is built 100% with Swift & SwiftUI.

yqiang··on I used AI-powered calorie counting apps, and they were even worse than expected
I'm working on an app in this area [1], and I've spent a lot of time exploring how to responsibly use AI for food tracking.

My conclusion is that while AI is excellent for augmenting your tracking experience, it's not yet reliable enough to be the primary tracking method. Consistency is key to successful food tracking, and AI can certainly help users avoid the common issue of missing a meal and losing momentum. However, inaccuracies, like consistently being off by 100-200 calories per day, can significantly impact results, especially for those on lower-calorie diets (like 1,200-1,500 calories/day, which is common for many women due to their physical size).

With FitBee I landed on communicating to the user that these are estimates and you probably shouldn't use it as your primary method of tracking calories.

yqiang··on Ask HN: What are you working on? (March 2025)
I'm working on a calorie & macro tracker called FitBee. Tracking my food has been tremendously helpful in terms of improving my health, but it's always been kind of a PITA. These past couple of months have been really exciting as I'm leaning into using AI to make it less of a hassle to track & provide more insights.

yqiang··on Ask HN: Spending Tracking Tools
I've tried a bunch, and while I'm reluctant to recommend a Quicken product, Quicken Simplifi is actually working out really well for my family and I. The UI is similar to Mint & it supports Apple Pay. I used to export all my data from Mint to a CSV for further cleanup/analysis, but the built-in tools in Simplifi are good enough now that I just do everything inside the app.
yqiang··on Show HN: I built an alternative to MyFitnessPal for calorie and macro tracking
I was overweight in college and started my weight loss journey using an app called MyFitnessPal. Tracking calories not only helped me lose weight but also taught me a lot about nutrition and helped establish healthy eating habits that continue to benefit me. However, I’ve always been frustrated by the existing nutrition tracking apps. They are slow and bloated, lack accurate nutrition data, or don’t respect user privacy. I wanted to build something that I’d love using myself.

A few things that make FitBee stand out:

* Fast, lightweight and to the point - The app is just about tracking your nutrition and makes that front and center. I've tried to make things that you do often as simple as possible (e.g., log yesterday's breakfast).

* Robust Apple Health support - You can read/write data to Apple Health. I wear an Apple Watch so it's great for getting the energy burned through exercises.

* Accurate nutrition data - The nutrition data is sourced from the USDA dataset and nutrition labels off the packages. I also spent effort adding east asian foods (e.g. things you get at 99 Ranch or Weee) to the database, since those were hard to find/track in other apps I've tried.

* Photo Logging - You can take a photo of a food and get an estimate of the calories and macros. It's not 100% accurate but it's been super helpful for me when eating at a restaurant that doesn't have published nutrition info.

* Recipe importing - You can pretty much point any recipe at the app and it'll import the ingredients and generate nutrition information for you. As I got more into fitness, I started to cook more so this has been super helpful.

* No Ads - The app is monetized via a subscription.

* Monetization - Most of the features are free, but there are a few which require a monthly or annual subscription. I also recently added a one time purchase option since a few folks had asked about it.

yqiang··on Ask HN: Those making $500/month on side projects in 2024 – Show and tell
I'm building a better calorie/macro tracker called FitBee: https://apps.apple.com/us/app/fitbee-calorie-counter/id64439...

Tracking my food has helped me get into much better shape but the leading apps in this space IMO are all quite clunky. I wanted to built something that was fast and lets you get on with your life.

A few stand out features:

- Nutrition label scanning if I don't have the food you're looking for - Photo Logging for restaurant meals or complex meals you don't want to manually track - It's light weight & fast - Interactive widgets for things like water tracking.

yqiang··on What Is Your RAM Usage on macOS? Share Your Workflow and Use Case
I work on an iOS app (FitBee) built primarily in SwiftUI. Xcode routinely takes about 5-6 gigs of ram. If I enable predictive code completion that’s another 2gb. Very glad I upgraded to a Mac mini m4 pro with 48gb of ram.

If you end up trying it, I'd love any feedback!

yqiang··on Reinventing Core Data Development with SwiftData Principles
+1 for GRDB. One of the best open source iOS SDKs I've used. The one downside I've run into vs. Core Data is that sharing a database between multiple processes (e.g., your main app and a widget) is not as well supported (to be fair, the quirks around this are documented extensively and quite well).
yqiang··on Ask HN: What are you working on (September 2024)?
https://fitbee.app I'm continuing to build the nutrition tracker I've always wanted myself [1]

This month the focus is improving food data quality & search relevancy. I'm also starting to experiment with some more advanced generative AI use cases in the realm of providing suggestions on what to eat & analysis of your diet.

yqiang··on Ask HN: What are you working on (August 2024)?
I'm building FitBee (https://apple.co/4aGUw5X) - a simple and user friendly alternative to MyFitnessPal. It's been really fun trying to figure out how to build the most frictionless food tracking app possible. I just launched a feature where you can get a calorie & macro estimate by taking a photo of your meal and am working on several improvements to it.

I have a small amount of experience building iOS apps but have never done anything with a backend before. This project is fairly backend heavy, so it's been quite a journey learning how to do everything from setting up a database to deciphering elasticsearch.

yqiang··on A fast, simple and privacy friendly MyFitnessPal alternative
Hey HN,

yqiang··on Ask HN: What macOS apps/programs do you use daily and recommend?
Craft - it's a nice note taking app with great sync. I use it on my Mac and iPhone daily.

Fork - one of the better git GUIs.

Rectangle - open source app to manage window layouts

yqiang··on SteerMouse
Unfortunately you can't seem to seem to turn it completely off on my MX Keys Mini. In the Logitech software there's a toggle to turn the backlight off completely.
yqiang··on SteerMouse
Does anyone know of a tool similar to SteerMouse that let's you control Logitech keyboard settings (e.g., turn off the backlight)? It's the only reason I still have the Logitech software installed.
yqiang··on Ask HN: What non-AI products are you working on?
I’m working on a nutrition tracking app for iOS called FitBee (https://fitbee.app). There’s been a huge number of “AI” based products in this space but they’ve all been relatively bad in terms of accuracy and reliability (eg the Humane AI pin demo). At some point I’m sure I’ll introduce some AI based features into the product, but for now I’m focused on making it the fastest and most convenient way of tracking your nutrition.
