Instagram Postings

[pauline23]

I have a question so hope someone can help me. I have many clients whom I manage their Instagram accounts, post etc I have only been using my laptop to do this via a program called Gramblr which works fine but I need to schedule ahead so I have bought a tablet, does anyone know how I can use my tablet to schedule and post to Instagram as I can’t seem to get it to do this, what app do I need (I do not have a smart phone)
Thanks
