Hello.
I am interested your project. I'd like to share a compilation of the best ways to promote your app. This list is in no specific order, so you should pick the ideas that most appeal to you, and that you think will best fit into your existing marketing plan.
1. Define your landing page
2. Start a blog
3. Create a video intro to your app
4. Ask for app reviews
5. Run an ad campaign on Facebook
I'm flexible with my working hours and am happy to work closely with any existing freelancers you work with.
Thank you in advance for your time and consideration.
I look forward to hearing from you!
