on1

on1 is a photography mobile app that provides software for photographers and learners. The job it does: designing and building iOS and Android apps.

The natural audience is businesses launching or rebuilding an app. Alongside the main category they mention Mobile Apps, Photo Editing and Photography. As a very small company team themselves (1 to 10 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

on1 is based in Portland, Oregon. More on on1.com.

Our checklist for this category: portfolio quality, app store experience, and maintenance terms. Get the renewal terms in writing before the first invoice.

If you have worked with on1, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
