I usually control my costs of travelling with a spreadsheet. Recently I have started using an app and I am really enjoying it. It's much easier to do: it does currency conversion, adds the location automatically, categorization, it's really great.
However, it's not free. It's not expensive either, but it's based on a subscription fee, and at this point I am not interested in adding yet another subscription-based service to my life. I am not happy with the fact that I am locked to a vendor either. They allow exporting information, but under specific conditions.
I am looking for an app, preferably free, that allows me to export data. I am ok with buying the app, if needed. But I am not interestedd in subscriptions.
I have looked for reviews, but these are not very systematic or lack detail. Are there any good resources comparing budget apps for travelling?
