What's the app idea you keep thinking about...

but haven't built yet?

[Ruberg Dev @RubergDev]

@iamvishal16_ios Sleeping on it is a good filter! Mant ideas are not so good the morning after

[Ruberg Dev @RubergDev]

One unexpected side effect of learning to build apps:

My Notes app is becoming dangerous.

Every annoying little problem is now:

“Could this be an app?”

Most ideas are probably terrible.

The problem is they all sound brilliant for the first 24 hours.

@Priyanka_093 @JonBuildsHQ For now it´s money, this isen´t my fulltime job yet so will need to mange by myself for a while

Sunday schedule:
- Family time
- Watch City game, then Newcastle - Pool
- Work on business while watching games
- Relax

Balance is everything. Family will always come first, then everything else. Remember to touch some grass 😊

@kedytcom Looks like we had the same idea:
https://t.co/Bi0cYCi0da

- iOS apps
- $1 bump to take the lead

[Ruberg Dev @RubergDev]

Something changed after my first person paid for Botkassa.

Not financially.

One customer obviously doesn't change anything there.

But mentally?

It changed a lot.

A stranger decided something I built solved a problem well enough to pay for it.

Now I don't really care about customer #100 yet.

I want to understand how to get customer #2-3-4-5.

A couple of weeks ago a friend of mine asked me how I built apps with ai. He had no experience, so I needed to explain it in simple terms. That´s why I made this article. https://t.co/MQ0JwNBbVw

[Ruberg Dev @RubergDev]

I know these bid sites is all over X at the moment. But really thought one app would pay $3 to outbid my two apps 😁

Guess not

Appwar is live ⚔️

The public app leaderboard is now open.

Want the top spot? Buy it for $1 more than the current leader.
Every takeover costs exactly $1 more. No estimates. No bidding wars. Just one dollar at a time.

[Ruberg Dev @RubergDev]

Will this be as popular? No
But it was fun to see what I could make in a day, I had never used Stripe before.

But it was fun to se what I could make in a day and I learned a lot. Had never used Stripe or Resend, now I know both

Yes I got the idea and copyed most of @jonathan_wilke https://t.co/CTfmlnS7ZZ that got a massive movement.

But I went a different route, this is Apple App Store apps only. Add your app store link, metadata is fetched and everything is ready in seconds. Add your X name for futher reach.

Set amount to pay, $1 more then the top spot.

[Ruberg Dev @RubergDev]

This is becoming a dangerous habit.
I encounter a small problem.

I think:
“Surely there’s an app for this.”

Five minutes later:
“…I could probably build this.”

That’s basically how Botkassa started.

I was sitting in Excel trying to keep track of small fines and payments, and it quickly turned into a mess. I just wanted a simple way to register them and share the overview with the group without overcomplicating things.

So now I'm building it, got paying customers and really enjoy developing the app.

[Ruberg Dev @RubergDev]

What system do you use to analyze the use of your app? And how do you track errors? Posthog, sentry etc?

[Ruberg Dev @RubergDev]

@pfernan95dev Yeah thats right.
I’m working on an article thats describing what everything does in an easy way. Hopefully someone starting up can have use of it 😁

[Ruberg Dev @RubergDev]

What confused me most when I started app development wasn't the code.

It was figuring out what everything actually did.

Expo?
Supabase?
Vercel?
Xcode?
Once I understood how the pieces fit together, everything became much easier.

[Ruberg Dev @RubergDev]

A few months ago, my goal was simple:

Learn how to build an app.
Now I have three apps live and another one in development.
And somehow I feel like I know less than when I started.
Because every problem I solve reveals another one.

Coding → distribution.
Downloads → retention.
Users → paying customers.

Turns out shipping the app just unlocks the next level.

[Ruberg Dev @RubergDev]

@kr0der Congratulations!

Keep em coming👌🏼
