Thanks for the feedback. For whatever you want to do with supabase, I don't know. The application I made doesn't use instances, everything is local, even the parsing.
Thanks for the feedback. I'm glad to see that ux is appreciated. I agree that adding sources could be simplified, it's my least favorite part to implement and I notice it shows. For the Darkmode there is one, you need to press the 3 dots at the top right, select settings and then press the first parameter "Night Mode".
However, I don't think it's a good idea to make it the default, as some people find it harder to read text written in white, and there's a lot of debate on the subject on which is better.
For the button, I was inspired by other popular applications that also put a button there, if the button is too distracting, it can be hidden from the settings, it's the setting below "Night Mode" which is "Display Read-All Button" but indeed the Hamburger menu could be better exploited.
If there's synchronization, you'll need an account, but you'll still be able to access the application even if you don't have an account. Synchronization also requires servers, so it would have a cost. The application should be profitable enough, so it's hard to envisage this feature at the moment.
Indeed, just maintaining it isn't very complicated, but finding features for which users would be willing to pay $10/month seems complicated to me, as the play store is very competitive.
I should expand. Let's take two worlds, one where you charge nothing, and one where you do.
In the first, I get an app, but you get nothing but a pat on the back. I enjoy something, you don't, eventually you get resentful seeing thousands of people using what you built so you decide to make money off it. At this point, it doesn't really matter how you do it, either with ads, subscription, or secret dark-web stuff, you'll change the game and your users will not trust you as an author and just uninstall the app.
In the other, you charge a one-off £4.99. This is really quite small, but I now know the author gets some value from me and we've entered into a understandable contract. You are in the same place as before, but now ~$4.99 richer, which is nice. In the future, you make a bit of money and want to make more money. So you can now raise the price which will affect only future users. You can now also produce other apps, which I'll also look at those and think, well, the first app was good, I'll try those because I trust the author.
I agree with you that finding a business model is difficult, but what motivates me at the moment to improve and maintain it is that I myself am a regular user of this application. I'm still thinking about it and that's why I'm still waiting to make the code open-source. Subscription is an idea, but I wonder what kind of features people would be willing to pay extra for? I don't want advertising, I think it degrades the application too much, or else voluntary advertising that users activate and in return receive money (like Brave does).
Not at the moment, but I'm hesitating. I've already started to Open sourced the suggested sources in the app : https://github.com/Martinviv/rss-sources . You can also ask me for design details if you want ...
Yes, because later on, when I have topics in languages other than English, I plan to allow users to have a language filter that will display the topics and countries that correspond to the selected language. But at the moment, as I only have topics in English and news sources by country, I've kept this structure
This is normal, at the moment only images (jpg, gifs...) are displayed in the feed. I've yet to add the ability to read other formats, like mp3 here in future update
Thanks for the feedback. In fact I hadn't worried about that because I thought that adding sources isn't something frequent even if it's a bit long at first and I thought that adding an "add source" button in the hamburger menu would be annoying since it wouldn't be used often.
