What would you include into your app development project if you had an opportunity to build a salon app from scratch?

In my opinion, the following features should be among the highest priority items:

• Appointment booking with real-time availability
• Online payment methods
• Automated reminders about appointments
• Customer reviews and ratings
• Membership programs or loyalty programs
• Service/stylist recommendation based on artificial intelligence
• Push notifications with discounts and appointments updates
• An intuitive dashboard for salon owners

I am interested in finding out whether you can mention some underrated yet extremely important feature which would significantly increase the user experience level.

Be a salon owner, a developer, a designer or a customer who often makes appointments for beauty services – your opinion matters!

• What features are essential?
• What does a common mistake of salon apps look like, according to you?
• Do you see any trends which can influence the salon app development in the future?

While researching this topic, I also found a detailed guide on salon app development that covers the development process, key features, and important considerations. I thought it might be a helpful resource for anyone exploring this space.
Looking forward to hearing everyone's thoughts and experiences!
