Ask HN: What's your quarantine side project?

I created an app called 'Calcula' (iOS - Free) to help individuals strengthen their math skills. Built with SwiftUI. I'm surprised by how much documentation and tutorials are available online!

But it's been really interesting learning the process of publishing an app. Each feature brings a 100 challenges but it's been fun overcoming every mountain.

I'm building a treasure hunt web app (for mobile). An app for exploring the city. Had to learn a lot about geo APIs. But may have a potential business model now for larger city-wide events. Have a redesign mocked up now. Started writing the week before Easter and finished the week after.

- Web geo APIs to guide you to the next "treasure".

- Webcam API to capture matching photo.

- "AI" for matching photos and answers to questions in the backend.

- the "AI" doesn't work well, planning to add a python Lambda with a better SSIM algo.

The hardest part so far has been permissions in iOS. If the user blocked geo permissions for Safari it is kind of a pain to enable again for a normal user. I haven't had a chance to test in Android yet but I presume that will present other challenges regarding permissions.

I built Logicboard: https://logicboard.com a tool for conducting remote programming interviews. It's like Google Hangouts + you can write/run code in over 28 languages.

It's kinda amazing how much you can learn building something new, I improved my Elixir, ReactJS and Devops skills.

I open-sourced a Python library that makes it easy to offload functions to AWS Lambda. Compared to other frameworks, it's a bit more like Celery instead of focusing on HTTP API.

https://github.com/CloudSnorkel/lovage/

app = lovage.Lovage(lovage.backends.AwsLambdaBackend("lovage-test"))

@app.task def hello(x): return x + 1

if __name__ == "__main__": app.deploy(root=".", requirements=["requests"]) print("hello.invoke(1) returned", hello.invoke(1))

Instead of stating something new, I updated and added all the features i wanted in an app. I built the app to help me make solutions for reagents in chemistry lab , I was getting irritated by the calculations every time i had to perform a reaction in lab. It balances any valid chemical equation and gives you stoichiometric calculations with support for limiting reagents. With their molar masses. Also supports equations with fractional atom molecule (Doped Materials)( which was the real reason i made this). It has 65k+ total downloads with 10k active users.
