As indie developers, we spend weeks or months building products without knowing whether anyone will actually pay for them.
A few days ago, I launched Pocket Interpreter, an offline AI translator for Android.
The idea was simple: create a translator that works without internet access.
Most translation apps depend on cloud services. I wanted something that could handle voice, text, and camera translation directly on the device while keeping user data private.
After finishing the app, I launched it on Google Play with a small experiment:
A $0.99 lifetime launch offer.
Honestly, I wasn't expecting much.
I shared the app on Reddit and waited.
A few hours later, I received my first sale.
Then another.
And another.
Soon, customers started appearing from different countries, including the United States, Japan, South Korea, Singapore, Malaysia, India, Australia, Mexico, Ukraine, and several European countries.
The revenue wasn't life-changing.
But the feeling was.
There's something special about seeing a complete stranger decide that something you built is worth paying for.
For me, those first sales were validation that the problem is real and that people are actively looking for offline translation solutions.
A few lessons from this launch:
1. Launch before it's perfect
There were still features I wanted to add.
I'm glad I launched anyway.
Real user feedback is far more valuable than guessing what users want.
2. Distribution matters
Building the app was only half the work.
Sharing it on Reddit and talking about it publicly brought the first users.
3. Small sales are still wins
Many developers focus only on big numbers.
The first customer is often the hardest one to get.
4. People care about privacy
One thing users repeatedly mentioned was the fact that Pocket Interpreter works offline and doesn't upload their conversations to the cloud.
That reinforced the importance of privacy-first software.
What's Next?
I'm continuing to improve Pocket Interpreter based on user feedback and usage patterns.
The goal is simple:
Build the best offline AI translator possible.
If you're an indie developer working on your own product, keep shipping.
