I did some searching in this space as I wanted a proper unit aware calculator for my phone. I ended up finding Frink and rink; but Frink's android app is atrocious, and Rink doesn't have one. I hope something like hissab can leverage Frink's unit list with a better interface.
I'd like to see an effort to add common constants. My standard test for an app like this is getting the diameter of earth in light seconds; which wasn't possible because Hissab doesn't have Earth's diameter.
Thanks a lot for sharing this. I will look at Frink and Rink and try to implement missing features in Hissab.
I will also add lot more constants in the future. Currently it only supports pi and e.
Calculating with natural language may seem promising, but is not as productive as traditional calculators, especially when the "natural language" is actually a fixed grammar resembling natural language instead of employing fully extensible natural language (with AI, for example).
According to its documentation, this calculator has really limited capabilities. and it even charges for functions like calculating averages and converting currency.
I suspect that the audience for this type of software is quite limited, primarily inexperienced users. Users seeking higher productivity may either consider advanced software like Mathematica, or ChatGPT/WolframAlpha for general natural language questions.
There is, for sure, a small learning curve, but for professionals that do lots of calculations day to day, it can save
time for them, specially with variables and reusing a previous result. This can then act like a simple spreadsheet, where you can play with numbers and see the results updating on the entire page.
Another advantage of Hissab over traditional calculators or even google search is the ability to see all your expressions at the same time as compared to alternatives where you can only do one line of calculations at a time and results disappear when performing another calculations.
Hissab is launched recently. Soon, I will be introducing the ability to calculate complex number, solve equations, calculus, probabilities, compound units etc on the Math side. also lot more calculations for computer science like IP address calculations, various hash algorithms calculators and many other features.
This will eventually become the all in one calculator to calculate anything.
Again, small learning curve, but beyond that it can save a lot of time for professionals and students.
Generative AI is quite bad a doing math and I would not believe the results it "guesses".
Mathematica and wolfram are in a different pricing tier, so hissab is like a poor man's mathematica.

Generally speaking, it's true. AI is quite bad at arithmetic. But as AI started learning to use tools things can be different. Haven't really looked into this but I think ChatGPT with WolframAlpha plugin (https://www.wolfram.com/wolfram-plugin-chatgpt/) can be helpful.
People won't use generative models when they already have a clear plan about what they're about to calculate - they'll use a calculator. When employing generative models, we're more like asking the AI for some insights on "how to compute" or "what to compute". Automatically performing these calculations and obtaining the result is more like a bonus.

I do believe the next stage of evolution for Hissab would be to integrate fully natural language via some form of AI, provided it gives accurate results.
I have known about ChatGPT plugins and wolfram's integration. In fact they provide APIs that I can integrate in hissab. But I need to do the cost analysis for that.
Sometimes you don’t want to solve problems in the abstract, you just want to know what a ten year million dollar loan is worth at eight percent interest or something natural language like that. I type it into Google and it usually unrolls it and calculates it pretty well or finds a site for the problem. I hope this calculator has a good natural language vocabulary.
ya google is great with understanding natural language and providing either direct result or pointing to appropriate website.
My goal is to improve Hissab's natural language capabilities as much as I can.
Also, regarding the example you mentioned about calculating interest, I will be adding those features in the form of a function like simple interest(principle=1M, rate=8%, duration=10 years) etc. Its not natural language, but once you learn, and you do this a lot, hissab will come handy.
Interesting idea, and it seems to work well for converting simple common units.
I'm looking forward to seeing how it progresses. I'd like it to be able to recognize and perform more involved calculations like converting L/100km to MPG fuel economy; which I tried and it was unable to do.
one thing i like is you are using "to" as a keyword for converting units instead of "in". i already bought opalcalc and soulver though, so i'm not keen to try this.
It was great to work with Ionic. I did consider the alternatives like React Native and Flutter. But Ionic is truly one framework for Single codebase that works on web, PWA and native OSs.
Also the UI elements are of high quality and easy to work with.
