7 years ago I learned to code and built an app to scratch my own itch.
It grew to 3500+ users.
😢 But, I failed to monetise it (< $1100 all-time revenue)
I abandoned the project 2 years ago and now I want to revive it.
Let me share my journey, here on 🦋

Tough days as an indie hacker recently…
- My 9-5 costs a lot of 🔋 recently 💀
- my agency cofounder got seriously sick and I had to take over some responsibilities 😕
- it’s a flu season and my kids are getting sick more often 😬
Anyone else feeling overwhelmed?

Day 12:
Massive UI overhaul.
After not touching the UI for 3 years I’m now rebuilding it.
Thanks to TailwindCSS the whole process is a breeze.
Also getting a lot of interesting feedback around pricing recommending to introduce annual plan.
What are your thoughts on that?

Time to call it a day.
Sending an email update after many, many, many months to your user base is scary as f*.
Let's look at the numbers tomorrow morning.
Let's try to relax now.
