    Totalizer, my second watch app, is decidedly less ambitious than the first one - but regardless, it is something I felt I had to make. After trying five different calculator apps, and finding annoying flaws in all of them, I decided to make a 'perfect' calculator app for the watch. Not the most feature loaded one, but one that can actually be used frustration-free, when needed. Here's what the app has:

    • Big, easy to hit buttons, while keeping everything you need on a single screen:
    [​IMG]
    Note that I've made the operator buttons narrower, so that the numeric buttons could be as large as possible - because the right screen side edge is really easy to hit correctly.

    • Perfect button responsiveness, as the app is native.
    • Quick launch - probably the quickest possible, actually.
    • Running total will update as you type, no need for the "=" button.
    • Full equation preview as you type. Equation preview is in the title bar, freeing space for bigger buttons.
    • Easily accessible "%" button, which I think is the most used feature for an app of this kind (to calculate a tip, a sale, or a price after tax).
    • Percent works as you'd expect it to:
    200+10% = 220
    100-10% = 90​
    I have no idea why so many calculator apps get this feature wrong.

    • One tap to add parentheses around the equation - just tap the running total number. Smart delete for parentheses - if you delete the right one, the left one gets deleted too.
    • The app has the secondary layout where the buttons are even bigger, and the operators can be reached with a button press, a screen swipe, or a crown rotation:

    • Complications for all the watch faces are available, for the quick app launch, and to display the last result.

    If all of the above sounds like "well, how else it should be working?" to you, then I've achieved what I've set to do. However, it took a lot of thinking, designing, adding, and subtracting (sorry, I just couldn't resist) to get there, which I think comes through when you start using it.

    The app is $0.99. It may seem simple, but it's really not something just thrown together, and I really believe it's better than what's out there, where it really matters.

    You can get it from here: https://itunes.apple.com/us/app/totalizer-no-nonsense-watch/id1114433409?ls=1&mt=8

    If you have any issues or suggestions, post them here, or through the support form on the website. I'll read and consider everything.

    I think app is a great idea, I have purchased today & will give further trial before reporting back further.
    I have it as a complication on my watch face.

    Thanks - I've been looking for an app like this for my watch - downloading now.

    Cheers,

    Looking at your signature, you seem to have a 38mm watch - I'm really curious how usable you'll find the app on a smaller screen. I don't have a physical 38mm for testing, and while it looks right in 38mm on a simulator, I know it's not the same thing as actually using it on a real device. Don't forget there's a second layout with bigger buttons, if the first layout buttons seem too small.

    Yes I do have the 38 mm watch. It's excellent - I'm using the default screen with no issues using it to calculate. This is the calculator app I had been waiting for - :). Great job!!

    Cheers,

    Curious about complications - is that mainly useful for quick launching it from your favourite watch face?

    Also - when doing percentages does it is okay the interim % before you hit =?
    Eg
    200+10% (displays 20 when you hit the % button), and then displays 220 when you hit =

    Can you also do 200*10%= to get 20? IR calculate the percentage rather than add/subtract it

    Complications also display the last calculated result (on those complications that provide enough text to support this). Smaller ones, like the circular one, are only used to launch the app.

    There's no = button on this calculator. It shows the result as you type. In your example, when you type:
    200+10 the result shown would be 210, and then when you press the % button, it would show 220.

    You can do 200*10%, the result shown will be 20.

    I just downloaded this... I like it! I'm forever having to pull out my phone when I'm shopping to figure out sale prices. This will be a useful app, I think!

    I've released a 2.0 update for the app, and it has a few watchOS3 specific enhancements:
    - You can use the Scribble input to enter whatever you want to calculate.
    - You can use the digital crown to increase / decrease the last entered number. I think thi has a nice real life application in a situation where you want to see how much your total amount will be impacted after adding a different tip.
    So for example, if you type (145 / 3)+15%, for 3 people with a 15% tip, if you spin the crown, number 15 will increase or decrease and you will instantly see an update of how much your share changes with higher or lower tip.

    This looks really good, is there any chance of different colour schemes? I'd love a colour scheme closer to the stock iPhone calculator, flat buttons, orange operators.

    Yes, I will do that. I was originally very hesitant to implement anything that would increase the app load time, but that's no longer an issue with watchOS3, if you keep the app in the dock.

    awesome job! Love the app and it's anchored in my dock. very useful.

    Thumbs up and keep it up! :)

    This takes me back to being a kid in 1982, I had the only calculator watch in school. Happy to support great design and look forward to future updates, any chance of scientific functions on a second screen or something like that? I don't personally use many but it would certainly be a selling point for a lot of other people. Great app, purchased!

    I could add scientific functions, but I can't possibly imagine anyone having much real life use for them on a watch :) Maybe I should add 3rd view with functions like that, but I noticed the launch time increases the more UI elements I add - which again won't be as much of a concern with OS3.

    I vote leave it as is, it's perfect! And just what I was looking for. When I got my watch I hit the App Store and the first calc that popped up was $10, no way lol. Thanks for a great product at a great price and thanks for posting on MR or I would of never seen this.

    Read this 3D by chance and immediately purchased it. Very good job, thank you.

    What's the point of being able to enter multiple operators in a row? E.g. 20+++10 = 30 or 20++-+10 = 10 or 20+*+10 = (breaks calculation).

    Apart from that, nice app :)

    There's nothing that you can permanently break by doing that - I figured you can always just delete back when you noticed you made an error like that. But it's a good point, it doesn't make sense to be able to enter something like that, so I will look into preventing it. What I don't want to end up with however is the loss of the immediacy of the response. If the check for the correctness of the input adds too much overhead, and the equation printout starts lagging behind your key press, I'd rather leave things as they are now.
