Ok let’s get this party started! I’ll be posting mostly here about my two apps AirAssist.app and Waterbomber.app! And perhaps some developer related thoughts in between!

Always looking to get the conversation started on anything product and design related 🙌
Why are people always doing their best to insult you 😅

I do wonder how all these quick AI tools will long term influence indie makers. Yes you can create tools much quicker, but will customers loose trust when they also get abandoned by the maintainers much more quickly (to prompt a new project)?

Now let’s see that website traffic spike 😂

@ironbrands.bsky.social was leuke podcast! Goed (en bekend) verhaal!
Moet en a) toch eens een keer bij de drinks gaan aansluiten en b) toch nog echt een keer simpel analytics gaan gebruiken 😅

What apps/sites are people using to track and share spotted planes?

Should I build this?

Foggy days over north west Europe are not good for business 🌫️

@revenuecat.com is there an option, or can we get an option, to toggle the graph to not start with 0 but with the lowest value in the chart? This graph looses a lot of nuance imo.

First time I’m seeing Waterbomber outrank AirAssist in daily downloads. Winter is normally the low season for both apps, but with the LA fires that changed a bit.

Waterbomer trial starts. You can see when Twitter accounts tracking the LA fires started noticing the app 📈

What is the poorest bit of software Apple has written? And why is it the macOS emoji picker?

How is a side project from the side project called? And how should we prioritize those against the main side project 😅

User with a good resolution for the new year!

My userbase is mostly UK and NL, and the fact that it’s now really foggy here for days is visibly affecting downloads of @airassist.app! Never thought off!

0 days since I wondered why review was taking so long but turned out I forgot to click this button again 🤓

Testing different weather providers. The ones that let you easily test the data, actually have poor data quality 🥲
The other ones force me to do sales calls, which I try to prevent.

Showing a notification for Android users on the iPhone build of your app is not the cross platform code share we’ve hoped for 😅

What is the moment you decide to design a full component library for your side project?
I do have components, but the design something’s feels not coherent between (similar) components 😅 doing a full detailed overhaul also feels a bit too low prio atm..

Wow, atproto is really really cool 🤯
So who wants a verified 'Microsoft' and 'Microsoft MVP' label on their profile and all the posts?

I just finished setting up @bluesky.ms as a labelling service.

Go subscribe to the label to start seeing labels on verified MVPs and Microsofties.

Still liking the design of my very first published React Native app from ~7 years ago.
