Tend is a text message based service designed to help users maintain regular contact with friends and loved ones. It operates entirely through SMS, requiring no app download or account creation. Users send a text message with the word "HELLO" to begin, then add contacts by providing a first name and last initial for each person. Tend then sends a gentle reminder approximately every two weeks to reach out to each added contact. The service tracks replies automatically and offers an optional web dashboard at app.tendsms.com for an overview of all contacts, though users can manage everything within their text messages. The service is free to use, with standard message and data rates from the user's carrier applying. Tend collects only the user's first name, phone number, and the first name and last initial of each added contact. The company states that it does not sell user data and provides a privacy policy for further details. Users can pause all reminders at any time by replying "STOP" to any message. The service is compatible with any phone capable of sending text messages, including non smartphone devices. Typical use cases involve individuals who want to stay in better touch with their social circle but find it easy to lose track of time between conversations. The workflow is simple: add a person, receive a periodic nudge, reply to confirm contact, and receive a follow up reminder after a few days if no reply is sent. Tend is designed to be low key and unobtrusive, focusing on real social connection rather than capturing user attention. The service was created by Sam Slesinger and is accessible via the website tendsms.com, with support available by email at hello@tendsms.com.
