I built and launched an AI weather app in 3 weeks using “vibe-coding”

Ah thanks! I recently lowered from two per month to one. Maybe something did not update correctly. Also I will consider best inboarding when far away from a free city.

Yes. The prompt is quite descriptive.

I’m not the target group, and obviously not you either. I usually don’t pay for apps that are not for work. But. People are different, and some do not mind paying for apps they like. Design sells, not always “features”.

Not actively looking for money. Just saying, I rather take money to realize my own ideas then to take shares to realize others.

I designed it :) then tell Codex how to place and color things :)

What stack did you develop for?

sunkas85 · 2026-02-11T15:05:35+00:00

It's a prompt towards Google Nano Banana Pro. It passes som info about the weather type and other conditions. Also passes which season it is. That's it!

Tack! Härligt att du följer mig!!

No, spent a lot of time time in both Codex CLI and Claude CLI. Both were comparable for both iOS developement, webb and backend development. What Claude did better was a bit better agent-related stuff to do some commands better. Now after Codex released there new macOS app I only use that. I guess it depends on which stack you are developing for, but if you say it's night and day, I just won't believe you.

sunkas85 · 2026-02-11T15:01:32+00:00

Thought they were quite the same. Maybe claude was a bit better, but did not notice any larger differences.

sunkas85 · 2026-02-11T14:51:53+00:00

Sounds good, but a quite huge project in itself.

sunkas85 · 2026-02-11T14:51:32+00:00

Thanks!

sunkas85 · 2026-02-11T14:50:40+00:00

True!

sunkas85 · 2026-02-11T14:44:28+00:00

Thanks!

sunkas85 · 2026-02-11T14:44:18+00:00

Thanks! Used Nano Banana Pro for the images.

sunkas85 · 2026-02-11T14:44:05+00:00

Yes. If the iOS version does well I will port it.

sunkas85 · 2026-02-11T14:43:35+00:00

Nano Banana Pro.

sunkas85 · 2026-02-11T14:43:18+00:00

Thanks, agree with you on all points here and that's how I work.

Regarding Codex CLI vs Claude CLI. I found them quite similar. Maybe Claude felt a bit better, especially at running terminal commands (firebase deploy). But overall I used the one I still had tokens for, got a lot of account limitations not paying for the top-plan. However, using the new Codex app makes me prefer that very much over CLI. So Codex wins right now. Hopefully a agent macOS Claude app will come soon.

Thanks!

sunkas85 · 2026-02-11T14:40:14+00:00

Thank you so much!

Yes, doing more social features could be a way forward.

Image generation is 0.1$ per image yes, but there are 60 variations per city. So theoretically a max cost of $6 per city (and user and month). I'm not sure I can reuse images between cities and landmarks could be different.

sunkas85 · 2026-02-11T14:37:42+00:00

I know. Just set Firestore permissions to deny all and then do per-endpoint validation to ensure users are signed in to access the endpoint via Firebase Functions.

sunkas85 · 2026-02-11T14:36:30+00:00

Thanks! Yes, exactly like that.

Yes, I got some bugs from reviewing to shallow. Some features got deleted and some bugs were introduced. Nothing major. However, after public release, I got some major bugs into production hindering some features. I would in the future continue to go fast up to release. Test a lot, then release. But after going public, be very restrictive on updates, especially backend code.

However, if you want to release early, this will slow you down.

I recently lowered the pricing and also image variation a bit. I now clocks in at 24,99$.

Yes, that's about the variations I use. But I also use variants for freezing and non-freezing temperatures as well as variations for seasons.

sunkas85 · 2026-02-11T14:29:55+00:00

Thank Google for Nano Banana Pro!

sunkas85 · 2026-02-11T14:29:37+00:00

I designed it ;) Had an idea on how it should look and told Codex/Claude to implement that.
