If you are browsing our subscription options on your iOS device (iPhone, iPad) then you may see 1-year and 3-month purchase options, but not a monthly subscription option.
You can, however, find the monthly subscription (with auto-renew) on our website at my.lupa.app.
Incidentally, we recommend making all purchases through our website. We can offer a higher level of customer service that way, and more of your dollars will end up supporting content production at Radio Ambulante, and product development at Jiveworld.
