AllTools.dev is a modern, fast, free online toolkit built for people who need quick, accurate calculators and converters without signing up, creating an account, or wading through cluttered interfaces. The platform offers 500+ tools across finance (mortgage calculators, loan amortization, compound interest, currency conversion, debt payoff, retirement planning), health (BMI, calorie needs, pregnancy tracking, ideal weight, body composition), math (scientific, statistical, geometric, percentage, fraction), science and engineering, date and time utilities, unit conversions (volume, length, temperature, power, area), developer utilities (JSON, regex, JWT, hashing), and interactive math and algorithm visualizations. Every tool is free and works instantly in the browser. No accounts, no paywalls, no sign-in walls, no data collection beyond standard analytics. Calculations happen client-side for speed and privacy. Unlike older established calculator sites that grew through 20 years of ad-heavy layouts and outdated UX, AllTools.dev is built fresh on Astro with a clean, mobile-first, accessibility-conscious interface. New calculators ship weekly based on user demand. Ideal for: students doing homework, developers needing quick conversions, finance-minded folks planning loans and investments, professionals doing scientific or engineering calculations, and anyone who just needs a fast answer without installing an app.

I use Notion but I have heard that the andriod experience is not the best. You may want to try Coda, Obsidian, Mem or Anytype. I know of a few others but I think for the purpose of a second brain these can do the trick itโs just about preference and which experience you like the most. Source: about 4 years ago

For supervising the trauma team I've also been playing with "Mem". https://get.mem.ai/. Source: over 4 years ago
I really love obsidian. Sure I t has a couple of wrinkles, the mobile app is new still and has a couple more wrinkles, but it scratches so many itches I have around note taking. Currently using it alongside https://get.mem.ai/ and love the pairing for knowledge base and real time notes. Iโm working from n combining the two to come up with my ideal set up. - Source: Hacker News / almost 5 years ago
