Some history: A couple of days ago my app finally got approved and released on app store.
Overall really happy with the release. Now I finally have something that I use every single day. Whereas previously I was using various different apps to journal, track habits, track my weight and manage tasks etc. Now I have all of that in one place.
Initially it was a website that I built for myself but I realised that something like this is better built in an app after speaking with lots of people.
I used Convex dev for my backend and that honestly made the backend part of creating this part very easy because I could just use the same structure I had for the web app. Convex was my choice because even for a website I wanted the data to always be in sync whether I access it on my phone or laptop.
The most annoying part about building an app is having to go through the review process of app store. For a website, I can just make a change and it can be live in less than a minute. But the app store review process alone took me 2 weeks to release this.
Using AI made migrating the website into an app really easy. I had some components like heat-maps and graphs which would have been really difficult to migrate over if I was doing this a couple of years back.
The idea itself actually came from reading lots of productivity books and then stumbling upon an interview from Jim Collins who talks about how he tracks his own life and makes sure it's going in a direction that he wants
