Just want to share a simple app with you - it can help you learn and understand cognitive bias. It has a simple play functionality where a random cognitive bias is shown everytime you click “a card” Url: [https://cognitive-bias.glideapp.io/](https://cognitive-bias.glideapp.io/) The app is copyable - so take a look under the hood. Inspired by a micro-site ( [https://joachimblicher.dk/pick-a-bias/](https://joachimblicher.dk/pick-a-bias/)) done by Joachim Blicher Another app focusing on cognitive biases is: [https://pocket-biases.glideapp.io/](https://pocket-biases.glideapp.io/) ---

Hi Kristian, your app is really nice. Two pieces of feedback: (1) Loading speed. - When I first launched the app, it took a very long time (15-20s) for all the cards to load in the “All cards” tab. - In the “Play” tab, cards take 1-2s to load. (2) Starting tab Have you considered setting the “Play” or “All cards” tabs as the starting tab, instead of the “Intro” tab? When I sign in to your app, I am having to navigate to another tab every time. An extra avoidable tap? ---

@nathanaelb thank you for your feedback. I haven’t had focus on the loading time. But sure could be better - and generally loading images are too slow in glide I think. Some sort of caching would be great. Good idea to move play to the first tab ---

Are you storing the image link in a GS or did you upload the images to the GDE directly? If you want to test, you could create a new tab for testing purposes and see in which tab the images load faster? ---

@nathanaelb I have uploaded all pdf files via Glide so they are stored at Glide so they should be sitting next to the app.
