Choosing well
Check the platforms you need
Tools in this category run across web, Android, iOS, API, macOS and Windows. Confirm the platforms offered by the tool before you commit.
For phone use, look for a stated Android app rather than assuming a web service has a native mobile app.
Compare free access and paid terms
A free plan is available from items in this category, and a free trial is available from items in this category. Check what the free option includes before moving bookings to it.
Compare the listed paid-from price, billing period and whether pricing is shown or available on request.
Review booking and calendar features
Check how the booking page works for your customers and compare calendar sync with the calendars you already use.
Availability rules can control when appointments or resources can be booked, so match them to your working hours and scheduling needs.
Match resources and locations
Compare the resource types supported by a tool, such as people, rooms or services, against what you need to schedule.
If you operate in more than one place, review the locations field and confirm that its availability rules can represent those places.
Check integrations and access
Native integrations can reduce manual steps between your booking system and other services. Compare the integrations listed for the tools you are considering.
An API may suit a custom booking flow or an internal system; check the platform details and documentation before choosing that route.
