Free42 VS Soulver 3 for Mac

My go-to recommendation for an RPN calculator is Free42 (https://thomasokken.com/free42/). It's available for Android, IOS, Mac, Windows, Linux. So you can use the same calculator everywhere. It emulates the real HP-42S calculator very closely, so if you happen to own a real HP-42S, you can switch back and forth without friction. If you don't want to pay the extortion prices for a used HP-42S on eBay, you can pick... Source: 5 months ago

HP15C is amazing but so is the HP42 and HP35S, with the 42 in particular considered by some people to be the best scientific calculator ever made. I have an HP35S which is great. I also have a swiss micros DM42[1] which is an absolutely fantastic calculator based on the Free42[2] opensource emulator. It's much more powerful than the HP42 while remaining 100% compatible. The only downside is the keys are quite a... - Source: Hacker News / 6 months ago

$275, swissmicros, SwissMicros DM42 w/ case. This is the best, most accurate dedicated handheld calculator on the market hands down.

Market is $150-200. Source: about 1 year ago

Have you seen Free42, "...a re-implementation of the HP-42S Scientific Programmable Calculator and HP-82240 Printer?" [0] It is available for Android, iOS, Windows, macOS, and Linux. (At one point there was even a version available on Windows Phone 8.) Perhaps it checks your boxes of good RPN calculator, available on all platforms. I don't know how much an HP-42S feels like a 41C. In any event, thank you for ralc.... - Source: Hacker News / about 2 years ago

This looks fantastic. I will definitely give it a spin. I've been tracking what I call "computational scratchpad" apps for a while now but haven't found one that fits my environment/workflow yet. Maybe Heynote will. Here are some others that I've looked at: * https://soulver.app Granddad of them all, Mac-only, proprietary, expensive * https://numi.app Mac-only, proprietary, semi-expensive.

I love the idea of a 'sheet' where you can add financial data and have it figure out what it needs to calculate. I would love to see this have the ability to draw simple graphs to show how your situation will look, or allow for things like interest rates on deposits, or the ability to see how your income might look like in X years with an Y% average increase, etc. PS: Also check: https://soulver.app/ for inspiration. - Source: Hacker News / 9 months ago
