Around 2-3 months after release Bucket crossed 250 downloads. It's not much, but it's honest work.
This traffic came mostly from posting on different channels (Reddit, IndieHackers etc.) and paid advertisement (AdWords). Although I didn't invest much yet.
I'm still planning in putting some money into Facebook/Instagram ads, but I'm waiting till I finish Share via web feature.
Most of the downloads are coming from Android version. For some reason iOS is not doing so well.
