Appointments, automatically remembered
dont4get.io is the free appointment second brain people keep on their phone. Platform holders pay monthly to prevent no-shows, while recipients get every important appointment remembered automatically.
Confirmed appointment
Tonight, 19:30
Incoming appointment
The simple idea
People should not copy appointments from emails, portals, booking confirmations, SMS messages or WhatsApp threads into a calendar. dont4get receives the confirmed appointment from the source system or message inbox and turns it into a clear reminder on the user's phone.
For app users
dont4get is built for people who do not want to manually copy bookings, confirmations and appointment emails into a calendar. Recipients use the app for free because platform holders fund the reminder layer.
Your phone number becomes the secure link between you and the appointments businesses send to dont4get.
Opt in to Gmail, Outlook, Microsoft 365 or SMS Inbox Mode so appointment messages can be recognized without storing unrelated content.
See who the appointment is with, how to contact them, where it is and when to leave. Reschedule or cancel when the business supports it.
Smart departure reminders
When the platform holder sends a logo, phone number, email address and geo-location with the appointment, dont4get can turn a simple reminder into a useful travel-aware prompt. With permission from the recipient, the app can use current location and traffic conditions to estimate when it is time to leave.
Inbox & SMS sharing
With optional Inbox Mode, dont4get can recognize appointment-related SMS messages and convert them into reminders. Users can also send simple SMS updates to others, for example to share an appointment, arrival time or important reminder.
Information for platform operators
dont4get gives reservation platforms, CRMs, scheduling tools and vertical software a simple way to deliver appointments to users without building reminder apps themselves.
No-show reduction
Because platform operators send appointments directly into dont4get, recipients do not have to copy anything themselves. The appointment arrives centrally on their phone, reminders are triggered automatically, and location-aware prompts can account for travel time and traffic. Supported cancellations or reschedules can flow back before the time slot is lost.
How appointments enter dont4get
Reservation and scheduling platforms send confirmed, changed and cancelled appointments directly to dont4get.
Users can connect email accounts so AI can recognize appointment confirmations. Non-appointment emails are ignored.
Businesses can send appointment SMS links, while users can optionally let dont4get recognize appointment SMS and send important updates back out.
API first
The platform starts with a clean appointment API and a connector model. When no API exists, dont4get supports controlled email intake, SMS intake and outbound SMS sharing so appointments can still become reminders.
