The Problem

Coaches, tutors, therapists, and other appointment-based operators cannot consistently manage recurring sessions, cancellation windows, and availability across scheduling and calendar systems. Synchronization errors can expose blocked times, shift appointments across time zones, omit meeting links, or send clients conflicting reminders. These failures create lost billable hours and require manual checking.

Potential Solution

Build a scheduling reliability layer that connects an operator's booking system and calendars, then continuously checks recurring appointments, blocked time, time zones, cancellation deadlines, and reminder content. It would flag or repair conflicts before clients are affected and provide a verified daily appointment list. The first version should focus narrowly on recurring sessions and 24-hour cancellation enforcement for solo service providers.

Why Now?

Appointment businesses increasingly combine booking platforms, multiple calendars, video meetings, email, and SMS, creating more opportunities for synchronization failures. The reviews span several calendar products and repeatedly describe operational consequences rather than a single transient defect.

Google Calendar: Get Organized

Can’t resize widgets I live by my calendar and need a good widget so I can see it at a glance without opening the app - the widget is so small it can only display 3 events. Needs to be resizable.

Google Calendar: Get Organized

Reminders don’t work I rely on a digital calendar to give me reminders. I don’t have many appointments, but they are important to me as I cannot afford to pay no show fees. Three time now over several months I have missed an appointment because I forgot about it and did not receive a notification when I explicitly set 3 different reminder times. Google Calendar has cost me $160 I don’t have.

Parchment: Agenda & Daily Note

Widget issues I have a lot of overdue reminders and the widget seems to take timed ones that were overdue a while back and place them in Today’s times list when I just need what is important from that day. Also it does not seem to work with smart lists.

Google Calendar: Get Organized

The app icon needs to update to current date! Why we are in 2026 and the app icon doesn’t automatically update to the current date, for one of the largest most technologically advanced companies in the world, is truly a mystery. I have to use Google Calendar for work, but hate it compared to Apple Calendar, solely because the app icon doesn’t update to the current date. Very frustrating and, to me, it seems like something that should be simple to implement that everyone would enjoy, unless you prefer pretending that the date is perpetually the 31st.
