I currently use Zoho for invoices and an iPhone app for tracking time as Zoho doesn't really work how I would prefer.

My workflow is that I have numerous clients, all pay a different hourly rate - but I dont really have projects - i just need to clock in and clock out and generate an invoice. The zoho time logging only works if you have a project - I could make a project for every single client but then It just gets too messy. Is there a possibility of soho changing how timers work in the future and being able to just start a timer and assign it to a project or just simply to a client?

I really want to be able to use Apple Watch to track time but it just won't work for me at the moment.

Any advice would be greatly received.
