Ever have an idea for an interesting app or an excited app and wanted a centralized place to keep track of it for future reference? This is the right app for you!
With Concept Pad, you can quickly create a concept and store it. You can then view it, edit it and share it.
Your concepts are synced between devices signed in with your Microsoft account.
