Yes, of course yes. You can access Tally on Cloud from any device, Any Operating System. In fact Enjay's Tally on Cloud works on RDP Technology and most of the devices available in the Market have RDP Client. Thats it, a RDP Client is all that is needed to run Tally on Cloud.
Even on desktops and laptops, all Operating Systems (like Windows, Linux, Mac) have RDP Client. That is enough to run Tally on Cloud.
