Highest-rated review5.0 / 5

Great time punch application

We really liked that the free version allows for accurate time tracking for those on a budget. Looking at the paid versions you get some serious value for your money. The user interface is smooth and allows for lots of different reporting.

Good, for 14 days

The process of adding an employee, it would be better to be able to send invitations.

Game Changer for us.

What I like the most about Sling is... I used to text message all of my employees to ler ask if they can work and then again to let them know when they are working! I no longer need to do that. They all know if they cant work they do the "Time Off request" if they can never work on such day they do "Unavailible" The natrue of our business are only events so we are somewhere different every event. Sling connects the address to the date as well. Its just been a total Game Changer a fee that we can afford!!

Great for Small Businesses

I felt the app has features that could be updated for better usage like employee adjust shift with management approval, forms, etc.

A closer look

ClockIt

ClockIt is an employee time clock and attendance platform that pairs a web and mobile app with physical biometric terminals. It is one of the few products in this category that talks to fingerprint and face terminals directly over the ZKTeco ADMS push protocol, so punches from a wall-mounted device land in the same timesheet as mobile and kiosk punches. Scheduling, leave, overtime rules and payroll-ready exports are included rather than tiered, and there is a free plan you can start on without talking to sales.

Strengths

  • Works with ZKTeco and eSSL biometric terminals over ADMS — most competitors are software-only
  • Scheduling, PTO and overtime rules included rather than gated behind a higher tier
  • Free plan, self-serve signup, no demo call required

Limitations

  • Smaller review base than the category leaders
  • Not built for client billing or invoicing workflows

Sling

Sling leads with scheduling — shift building, availability, swaps and labour-cost guardrails that warn a manager before a schedule blows the budget. Time tracking is present and competent but secondary to the scheduling engine. Its low entry price makes it a common first paid tool for small shift teams, and the reason it turns up against Homebase and When I Work more often than against project trackers.

Strengths

  • Strong scheduling with labour-cost warnings
  • Low per-user entry price
  • Shift swaps and availability handled well

Limitations

  • Time tracking is secondary to scheduling
  • No biometric hardware support
