Ability to use a calculator when entering bill
When entering a bill, it would be handy if there's a quick plus button there so that I can add multiple items fast and easy.
Currently there's an empty button on the number pad that shows up which I think could very well be used for simple plus/minus calculations.
We just added a very basic calculator function to our web app, so you can now use basic mathematical operations when entering a cost (addition, subtraction, multiplication, and division). We hope to add similar features to our mobile apps at some point in the future!

In Japan prices are without taxes; we needed to do divide by adjustment, but having just the price without taxes we had to calculate them manually. Would it be possible to allow formulas in the adjustment forms, so to be able to do like 550*1.08 (to add taxes) or 550/2 (if the adjustment is half an item)?

It's been 2 years, since the original idea is approved. Where is the Calc. It is a basic utility that this kind of apps must have. If you guys are not able to do so or busy so much, give it to me, I will implement it.

We don't add add single item every time. For eg if my friend buy 5 things, which will be going to be shared equally in group. Then we have to calculate the amount manually and add it.
It will be great if we have a calculator at the time of adding new bill, that too just next to amount field.
Kindly look into this request.
Thanks & Regards

Halo

if you have a grocery bill for example and A is supposed to pay a few things, it would be cool to add up the costs in the app directly.
thanks for this great app!

As an additional feature can you add evaluation of expressions as well while entering a amount for an individual, for example a bill contains multiple items purchased by a person and ability to add individuals expense in way like (45+658+98) which automatically evaluates to a number would be great feature.

That would be awesome!

See this link for a great example implementation in another app (WieBetaaltWat/WhoPaidWhat):

Having options of addition, substraction, multiplication etc when adding item so it will be easier to total the amount in the bill.

Please add this also to split unequally.

Geoff Summers commented
This would be an excellent idea

sometimes I want to combine few values together and create just one evtry. I want the amount field to support simple expressions like "20+4.34+56".

You should add this feature to any number field for example when splitting unequally.
Would be nice to have this in the splitwise mobile app as itemised bill is not implemented there.I suggest it works like this: the feature resolves an expression i.e. 1.11+0.51+0.70/2 when leaving the field and it replaces the field with the resulting amount 1.97. There is no need to see the expression afterwards or how I got there as its purely a calculator.

add easy to access calculator within app. Take receipt from online Walmart herb amazon etc accounts

It would be better if amount added can support mathematical calculations

Joures Lim commented
Please add in calculator to count in separate debt. Especially in those situation that two persons carry different amount to add up.
