About
Tools are grouped into categories such as Pay & Work, Finance & Shopping, Health & Fitness, Math & Conversion, Date & Time, Text Tools, and Developer tools, with a ⌘K search palette plus recent and favorite lists for quick access. Calculators like the Time Card and Overtime Pay tools turn hours and hourly rates into weekly totals and pay estimates. The site describes its utilities as browser-based and private by design, so the same pages cover both everyday calculations and developer tasks like JWT decoding and regex testing.
Key Features
- Calculate tips, tax, totals, and split restaurant bills
- Estimate loan payments, compound growth, and debt payoff timelines
- Track daily work times and compute weekly hours and overtime pay
- Decode JWT tokens and format or diff JSON in the browser
- Generate passwords, GUIDs, QR codes, and hashes on demand
- Use ⌘K search with recent and favorite tools for quick access
Use Cases
- Calculate an hourly employee's overtime pay or weekly hours from a time card
- Work out a restaurant tip, tax, and bill split in seconds without signing up
- Estimate loan payments, compound interest, or a debt payoff timeline with a fixed monthly payment
Who it is for
- Hourly workers and shoppers checking pay, discounts, and everyday math.
- Developers who need quick browser tools for JSON, Base64, hashing, JWT decoding, and regex testing.
