Cliche-Beer money from my phone

I’m after making some ‘beer money’ to supplement my decent salary as I’m in the process of buying my first home. I live in a somewhat quiet area so the mystery shopper things aren’t really any good for me as they’re a distance away but I have tried. I’m looking into bank switching for free cash but I want something more sustainable that’ll make me a few quid or whatever a day from my phone. Feels like a long shot but I appreciate any guidance
