No!
You or your guests are not required to download or install an app.
Once you purchase your BlushDrop for $39, we'll give you a link to upload everyone's video. They can do the uploading themselves.
We have free tent cards that you can print yourself to encourage guests to upload special greetings between courses at dinner or during the evening. No app required, and no cost to your guests to upload.
Your unique BlushDrop URL serves two purposes: your guests see a simple version with a box to handle uploads. When you're logged in, you see more details like billing information.
