Hello mickieLADQN,
Thank you for contacting Autodesk.
You have posted to the "BIM 360 Plans" forum. Just to confirm, when you are referring to "plans", you are referring to functionality within the BIM 360 Plan service and not the Plans functionality that is available within BIM 360 Docs, is that correct? If so, there is an iPad application for BIM 360 Plan. Search the App Store for BIM 360 Plan. Once the app has been downloaded and successfully installed on the iPad, any project user should have access to both the web and iPad applications using their Autodesk account login credentials.
If this answers your question, please click the "accept as solution" button. Otherwise, please let me know how I may help further.
Thanks,
Don
