Useful web alternative to Soulver, especially on Linux
From 2 comments
This looks pretty cool. I've long been looking for something similar to Soulver (https://soulver.app/) that I can use on Linux. This seems promising. One small criticism: In my…
bww on HNThis is great! Love Soulver too, but having it in the browser is fantastic. Well done!

Nice work on getting this out. I think it looks pretty neat and simple to use. I’ve had some issues when using it though: - on mobile, moving the cursor in a calculation doesn’t…

There are a few bugs as people have mentioned but the currency support is a huge win for me. Thanks for making this!

Calculation bugs with operator precedence and units
From 4 comments
There is something wrong with the order of operations. When I type 2+2*2-6 i get -6 which should be 0.
brospars on HN2+2 -> 4 ok 2+22 -> 6 ok 2+22-3 -> 0 What?
botinko on HNWhen I type `4W*3hours` the result is `12 mWh`. Same with `12Wh/3hours = 4kW`

Date and time arithmetic inaccurate
From 1 comment
This is really neat, but you need to rethink the date/time/duration arithmetics. You’re equating 12 months with 365.25 days, which gives rise to results like “1 month - 31 days”…

Desktop version or open source
From 2 comments
Looks nice! Making the result blocks non-text is handy. Any plans to open source this or sell a desktop version? I've long been a fan of http://calca.io but it doesn't run on…
elcritch on HNGlad you like it! I've got a desktop version in the works, and if the web version gets enough interest I'll finish it off.

Time-of-day and per-minute formatting (min/km)
From 1 comment
It would be cool if "6 minutes / 1 mile in min/km" showed `3:44` instead of (in addition to?) `3.7268` I wrote my own little calculator, much less general than this, to answer…

Byte and bit units
From 1 comment
Can you add bit and byte values, as well as units per unit of time please? Base 10 (GB for example) and base 2 (GiB) would be very handy. Full words as an alias as well, so GB ->…

Is it open source?

Super cool. I wish this was open source so I could see how you did some things, but I understand you've decided to keep it closed. Just to satisfy my curiosity, would you mind…
