Toggl (try writing it with the spell check on) offers native apps for both Mac and iOS. You can use it as a free app (fine for small freelancers) or choose a subscription-based version (from $9/month) for even more features. More information about what Zoho offers broadly is available online. Some features are limited to subscribers only. Projects is free for up to three users on two projects with a sliding scale of per-user subscriptions available. Zoho Projects is the company's time tracking tool. This lets you track time, assign it to individual projects, create workflows and it integrates with the company’s own suite of apps, along with Slack, Google and a range of third-party enterprise solutions providers.
