App Store Optimization (ASO)

Building a great app is half the battle. Getting it seen is the other half. App Store Optimization (ASO) is the difference between 2 downloads a day and 2,000. I optimize your App Store and Google Play listings to improve keyword rankings, conversion rates, and downloads — without spending a cent on ads.

Working together remotely

Most of my projects run remotely, and in practice that changes very little. We talk over video whenever you need to, not only at major milestones, and you can reach me with questions at any point during the project — I always answer.

Once we are working together, travelling to meet you on site can absolutely be arranged if your project calls for it. Travel costs are quoted separately, upfront and with no surprises.
