Useful too but could be better. It would great if the currency converter gave you a wider country currency choice not just a few chosen ones. Have sent an email to the developer on this but no response or acknowledgement was given. Been able to ensure you are using the latest conversion rate will be great plus. as per the other app capabilities they cover all of ones needs

Thank you for your suggestion! As a free and open-source application, we must manage operational costs carefully. We currently rely on the exchange rates freely provided by the European Central Bank (ECB), which unfortunately limits the available currencies. We hope to find another reliable, cost-free source to expand coverage in the future.

Thanks for the update, love the property selection and the nice Pure black theme. I would only mention that Pure black theme has some flickering when entering the app and when entering/exiting settings (probably an effect). I can sort of see it switching from the standard to Pure black theme. (S24 Ultra) Also, I would like to be able to enter settings directly from the start screen and a backup/import to/from file option for all customization inside the app.
