Why?

Most online calorie and macronutrient calculators lock you into a single formula and a generic recommendation. MacroCalc was built to compare the well-known scientific equations side by side and to let the user adjust every input — weight, height, age, gender, activity, and goal — while seeing the macro split update instantly.

What exactly?

MacroCalc estimates BMR (Basal Metabolic Rate), LBM (Lean Body Mass) and the daily macro distribution (protein / fat / carbs) according to the selected goal: maintenance, surplus or definition.

• Multiple LBM formulas: Boer, James, Hume — or manual input.
• Multiple BMR formulas: Mifflin–St Jeor, Revised Harris–Benedict and Katch–McArdle.
• Goal adjustments: ±300 kcal offsets and tailored protein / fat / carb ratios.
• Reactive UI: every slider or dropdown change cascades through the calculations in real time.

Local AI on the desktop version

The standout feature of the desktop build is a fully local AI: a small language model is downloaded once and then runs entirely on the user’s machine via Transformers.js with WebGPU acceleration (and a WASM fallback). It generates personalized nutrition tips and translations based on the user’s profile and goal — without sending any data to a server, with no API keys and no cloud dependency. Everything happens on-device.

Why?

Podcaster was created to make it easier for people to access the best podcasts recommended by Apple. With the vast number of podcasts available, it can be overwhelming, so this tool helps users discover quality content quickly and easily.

• Listen: It provides links or players to listen to episodes directly from the site, making the experience seamless without having to leave the page.

Why?

Let supose that we have to join two excel sheets to get data from both and get a file with the records that match with the condition that we wish. How would you do that? Nowadays Excel himself has an option to do that but it’s not easy to use and let alone intuitive

What exactly?

Jjoin is a desktop app developed with web technologies.

Consists in three intuitive screens that will guide you through the joining process of the excel sheets:

• In the first screen you will select the files.
• In the second screen you will create the condition to join the files.
• And last you will choose wich fields of both sheets you want to record in the new file. Also you will choose if you want to save only one file with every match and/or to save as many files as matches with the data/fields that you want
