Hi HN! I built a native iPhone and iPad whiteboard app on top of the open source Excalidraw libraries, combining them with several other open source components to create a polished offline experience. I also added features like AirPlay presentation mode with an integrated laser pointer, along with over 100 fonts and 400 backgrounds for customization. It was a fun project that brings together a...

I built a similar tool to what OP shared, mainly for debts instead of investments, and I completely agree with you. My app only uses iCloud to sync and it keeps all sensitive data on the user's phone. Another benefit I want to share about this approach is it means that apps built local-only will never have the risk of one day going offline and being inaccessible due to the company closing down or turning off the server.

This looks really nice, and I love that it's open source and all the data is saved locally. I will give it a try this weekend!

Hi Hacker News!My first iphone app is a simple personal finance utility. The interface lets you plug in the debts and savings goals you have, and the UI displays a dashboard to monitor those debts and savings.Screenshots & UI: https://www.reddit.com/r/iOSProgramming/s/JfJjruelgRApp Store Link: https://apps.apple.com/us/app/downpay-track-debt-savings/id6...My goal was to make the app easy to...

Re:Show HN: Skip – Build native iOS and Android apps from a single Swi... on Wednesday August 28, 2024 @06:54PM (#41385320)

Loving this so far, I've been working with it for a week now. I have a personal app, DownPay for iOS, that is built with SwiftUI that I want to bring to Android. I tried going the React Native route to build an android-only version but the context switching between SwiftUI, React Native, and then my day job made it challenging. I also tried Ionic and Ignite and wasn't successful with those either.

After testing the feasibility of other cross-platform frameworks, I landed on Skip. I LOVE that I don't have to break out of the "Swift" mental context, I just have to focus on writing an app in 1 language.

So before I commit fully I've been testing it out (building a demo app this week) and so far I am very impressed. The syntax to write platform-specific code (#if !SKIP #endif) is very easy to use once you get the hang of it.

It's amazing I don't have to learn Android to get something up and running at this speed with Skip. Hitting run in xcode and watching both emulators open feels like magic. I want to put this to the test so I plan to build a complete App with it from start to finish, ship it to both App Stores, and if all that goes smoothly I will proceed to migrate my main app using Skip.
