Hi HN. I poured months into making a mobile app called Codala, but sadly, it's getting practically zero downloads. I have no marketing budget at all.I'm starting to question if the app is just bad, but the core idea feels solid to me: you scan any QR code or barcode, and it opens up a space to chat, leave reviews, and discuss that specific product or place.I know the app needs users leaving comments to feel alive, but it's been 3 weeks and things are dead quiet. If you want to take a look, I’m totally open to any feedback or honesty.It's only available on Google Play for now
