Meetings, events, and conferences are great places to hire new mobile app users. Bring a stack of business cards with links to download your app and give them to everyone you talk to. Some meetups may have hundreds of people, but a conference may have thousands. Have a brief introductory conversation with the people at the party and give them a business card. Suggest they check out the app and contact you for feedback. This is a great way to bring more new users to the app and get feedback to improve. And to save yourself from all the marketing efforts, you can hire BrandLoom to take care of your app marketing.
