Does Setnayan have a mobile app?
Setnayan works on your phone. Open setnayan.com in Safari on iPhone or Chrome on Android and add it to your home screen — it then opens full screen, like an app, with nothing to download. On a computer, there is a desktop app for Mac and Windows at setnayan.com/download.
Yes — you are using it. Everything you plan here is saved to your Setnayan account, so it is the same wherever you sign in.
