ATOT Effect Required!!

[JJChicken]

Hey guys,

Seeking the legendary and mythical ATOT effect

Are any of you fans of Reverse Polish Notation (RPN) calculators, such as the HP 12C, 15C, etc?

For those that don't know, RPN is a better way of doing calculations

Instead of doing 3 + 5 = 8, you do the following

3
ENTER
5
+

Sounds like a trivial, meaningless change, but it is much more intuitive with how our brains think, and after a few tries, you will never go back

I fell in love with my HP12C when I became an accountant for a few years. I've recreated this application for iPhone, completely free, hoping you guys will give it a shot

https://apps.apple.com/au/app/rpn-30/id1451413517

Leave feedback if you like it. My only goal is to crack 10,000 downloads so I can put it on my resume. No world domination plans here

The AT effect is indeed mythical now. Place is dead to such things.

I also loved my old HP calculator, and used one of these apps on an older android phone in previous years.

I'd try it out if I had an IPhone but I have a feeling I wouldn't like it. I'm perfectly happy with a "normal" calculator, but like I said I'd still give yours a shot. Gotta help out the ATOT brethren.

I'll have to post here when I finally finish my mobile game. I'm expecting about 10 downloads. Maybe if I post here I'll break 15! Woot

I used HP calculators exclusively in high school and college. I was disappointed when I won a TI in a contest once.

I'd download your app except for the minor problem that I don't have an iPhone. I do have Droid48 on this Android phone, though I don't use it much.

What's the game? Best of luck!

If I only I was good enough to learn how to do both iOS and Android - didn't realise how much work programming actually takes The hours fixing the minor most details...wish I could grow up in the command line era and not have to program UI

 

[JJChicken]

Also @clamum you would be surprised at how many downloads you get. I'm at over 100 downloads over 6 months of having this app (its free), and even got a thank you from somebody in Brazil, made my day that somebody actually uses my app

 

[FeuerFrei]

I don't use apple store.

Reminds me of my HP 48G in college.

HP calculators are the best. I don't mind the TI - 30 II B, used that in high school (best history function), but the joys of doing calculations on a HP

There are TONS of tools out there to help you develop iOS and Android simultaneously. If I were to start another app any time soon, no chance I would do native iOS or Android and would be using one of the other platforms.

Do you get the same functionality though? Does android use storyboards etc.

Because I find there's quite a few specific things to the iOS programming platform - I was frequently hitting the walls of what is possible as I worked to get the best user experience possible.

What I HATE right now (and I'm going off topic on my own thread ) is that you can't have iOS apps running in the background...I sooooo want to create a true p2p messaging app that doesn't require going through a server

What apps have you built?

I've built many strategy guides for fighting games as well as a game. My most recent one is a live video dating app that we are relaunching shortly, Spottle, https://spottle.app . That one is by far the most in depth one using many 3rd party apps and has a backend and database.

Storyboards are nothing special and I'd argue that using them is a bad idea. If you know how to make views programmatically it's way more powerful than using storyboards. And that is coming from someone who wrote that whole Spottle app using storyboards. Storyboards are also a shit show when you have to merge changes from another branch or have multiple people working on the same storyboard in a branch.

I'm talking about stuff like React Native which is 100% what I would write an app in if I did it all over again. Right now that app is only iOS because it's all in Swift. If it was in React Native, we could deploy to both platforms, with some specific platform code for certain functionality.

I don't do Apple, but you have my full endorsement for your endeavors. RPN is the only way to calculate. For Android, Droid48 was mentioned above, and I also use Free42. A complete libre software rewrite of the hp42s calculator...

That app looks great and the idea sounds great. Hope the best for it.

Yeah you are right, doing views programmatically is really great - its been a while since I coded (6 months), but now I remember I actually did all the views programmatically.

I think I’ve really bought into Swift, hence feeling scared to go down a third party approach. It makes sense though, I’m really limiting myself to Apple only. My view is if I ever get a good idea, I’m just gonna hire a gun Android programmer to create something for me there / manage both apps, while I work on the fundraising / business model.

Yep. I'm using Unity for this game, and it can build to Android/iOS/PC/a-million-other-devices. I know of Xamarin but I don't think that's used for games as much, that's mainly for just regular mobile apps as I understand it.

But man, I cannot say enough good things about Unity. For free you have access to this incredible game development environment. Combine that with Visual Studio being free (Community version) and wow... it's a golden era for developers.

‎Reverse Polish Notation ("RPN") is an alternative way to complete calculations. Many find it to be more intuitive and user-friendly than the "normal" way of using a calculator. RPN works entering numbers first and then the operator (i.e. 53 47 + will give you 53 + 47 = 100). This is my...

That's the one I've been using on iPhone. I like it.

In hindsight I wish the app was never started in Swift. When new versions of Swift come out it's a huge pain in the ass to convert to those versions. And then if you had Cocoa Pods that use old versions, you can have issues with those as well. Sticking to Objective-C would have been the best bet but it's way too late for that.

I started an online turnbased multiplayer game in Unity but never got around to finishing it. I started it in JS but quickly realized using 3rd party libraries with C# and JS mixed wasn't going to work, so I converted everything to C#. That was my first and only experience with C#. Then my son was born and I just never got back to it.

The game I wrote was using Cocos 2D for iOS. I then used Apportable to port it to Android with nearly one click. I did have to write some native code and bridge it on Android though because I did things like Facebook and Twitter sharing, as well as Admob.

I'll just sit over here in the corner.

I like Sharp.

I purchased an HP11C around 1983 to use in my college classes. Still have it and it still works great! Sure, I will give your app a look.

when I was in school we used our brain! calculators were not invented yet!!

 

[BarkingGhostar]

I had a 12C. Loved the fact it was RPN. Years later I got an HP48 and found it way too much. But this was when I got into Physics and learned to derive my equations and numbers were deemed not so much important. Man, this is taking me back way too many years.

So you're, what, about 4,000 years old?
