Experiment 001 ★ Flagship

Personal Best

personalbest.madsciencelabs.tech

The only person you're racing is the one you were last time.

Your fastest 5K. Your heaviest deadlift. Your longest paddle. Your most pull-ups in a row. Personal Best keeps every record you care about in one place, and makes beating them feel like a big deal.

Log an effort in seconds. Your best is always on top, the chart shows how far you've come, and the moment you set a new PB, you'll know. Tracking stops being homework and starts feeling like a game you're winning.

Experiment 002

Inventory

inventory.madsciencelabs.tech

Count the shelf in minutes, not hours.

Stock counts usually mean a clipboard, a spreadsheet, and someone squinting at bad handwriting. Inventory turns it into a quick walk-through on your phone: type a number, hit Enter, move to the next item. Done.

Behind the bar, in a restaurant kitchen, in the stockroom, the pantry or the garage: if you keep stuff and need to know how much is left, this is your new favorite chore.
