Your customers can easily download the App to their phones by adding your app to their home screen and you can see on the link here how they do it:
This solution is better than upload the App to the stores due to several reasons:
1 - The App won't take space on your customer's phone, only a few (KB's) kilobytes.
2 - You can create your App within a minute, instead of waiting almost one month to get approval from Apple and Google to upload your App to the stores, and they can easily reject your App and you avoid this issue.
3 - Changing the Image logo of your App or name not required to resubmit it to an apple or google for approval which requires from you more money, another time to wait for their approval, instead, you can easily change it from the AppsVillage App admin.
4 - Several weeks from the moment your App will launch, it will appear on AppsVillage Store: https://store.appsvillage.com/
