18yo first iOS app: blocks distracting apps and unlocks with QR/barcode
I built Recode because I realized I was spending 8-10 hours a day on my phone pretty consistently. I tried other screen time apps but I found them too easy to bypass and end my blocks whenever I wanted to use an app. My solution was to build an app blocker app that makes users have to scan a physical QR/barcode to take a break from their app blocks. This helped me be able to get my screen time down to just a few hours everyday since I didn't want to physically get up and go across the house to get my barcode. Anyways, since it worked for me I felt like sharing it. App store link:…
In plain words
Recode is an iOS app blocker that prevents users from easily bypassing restrictions by requiring them to scan a physical QR or barcode code to unlock blocked apps. Designed for people struggling with excessive phone use, it adds friction to the process of taking breaks from app blocks, encouraging users to reconsider whether they really need to interrupt their focus. The app helped its creator reduce daily screen time from 8-10 hours to just a few hours by making it inconvenient to disable blocks without leaving their phone behind.

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
