Compare

Most people land here because they already tried something else. A tool that synced one direction when they needed both. A scheduling app that does everything except the one thing they came for, which is keeping two calendars in step. A Zapier zap that worked until an event got edited and a duplicate showed up. The pages below put Hetk next to the tool you’re weighing, feature by feature, so you can see where the line actually falls.

A few distinctions matter more than the marketing on either side, so it helps to know what to look for.

Sync versus scheduling. Reclaim, Clockwise, and Motion are scheduling tools. They book meetings, defend focus time, or hand out a booking link. Calendly does scheduling links. Some of them copy events between calendars as a side effect, but that isn’t their job, and it shows the moment you need two-way sync or privacy controls. Hetk does one thing: it keeps the calendars themselves in step. If you want both, you’ll likely run a scheduling tool and Hetk, and the comparison pages say so plainly rather than pretend one replaces the other.

One-way versus bi-directional. A surprising number of tools only push events one direction, or charge extra for the second. Hetk treats direction as a per-pair setting: one-way where you want a read-only mirror, bi-directional where events made in either calendar should appear in the other. That is set per sync relationship, not per account, so a single setup can mix both.

Privacy on shared calendars. This is where most alternatives fall short. If you sync a work calendar into a shared family calendar, or a client calendar into a firm calendar, the details usually come along for the ride. Hetk can replace a synced event’s details with “Busy”, so the title, description, and location never leave the source. Attendees are never copied at all. For anyone bound by confidentiality, that is the feature that decides it.

Price. Hetk’s Personal plan is $15/year, and the early-adopter rate is $10/year. Several tools on these pages charge more than that per month. A lower price doesn’t win on its own, so each comparison is honest about where a pricier tool genuinely does more.
