Most online calculators are buried inside bloated apps that require sign-ups, push notifications, or subscriptions just to do simple math. Dormant Labs takes a different approach: one tool, one purpose, no friction. Every calculator here loads instantly, works on any device, and asks for nothing in return.
Each tool is built around a specific real-world task — estimating paint for a renovation, figuring out how many moving boxes you need, adjusting a recipe when you're missing the right pan. The math is pre-researched so you don't have to look it up: industry-standard coverage rates for paint, density-corrected wax weights for candle making, gauge-adjusted yardage for knitting and crochet.
We add new tools when we find a calculation that's genuinely tedious to do by hand and doesn't have a clean, free solution online. If there's a tool you'd find useful, we'd love to hear about it.
