Tether Me — one tap a day to stay close to the ones you love. Life gets busy. We don't always have time to call — but we always wonder how the people we love are doing. Tether Me turns that wondering into peace of mind with a single daily tap. Just press "I'm okay today." That's it. Your circle instantly knows you're doing fine. And if you ever go quiet past your check-in window, Tether Me automatically reaches out to the people who care about you — so no one is ever left wondering, and no one is ever truly alone. Who it's for Adult children keeping in touch with aging parents from a distance. Elderly parents living independently, solo travelers and digital nomads, people managing daily medications, remote workers, and anyone who lives on their own but wants to give their family one less thing to worry about. It's made for people who value their freedom while staying connected to the ones who love them. How it works Check in — one tap on the big green button, once a day. Add how you're feeling if you like. Your circle is notified — loved ones get a gentle "all good" message in the chat app they already use. If you go quiet — miss your window and Tether Me steps in, reaching your group automatically through gentle, escalating reminders, so someone who cares can check on you. Key features One-tap daily check-in — effortless, even for those who aren't tech-savvy Share how you feel — add a mood to your check-in, so family sees more than just "still here" Works with Telegram & LINE — updates arrive right in the chat app your family already opens every day. LINE is perfect for families in Japan, Thailand and across Asia; Telegram for everyone else Automatic quiet-day reminders — if you don't check in, your circle is told — it works even when your phone is off, because the reminder logic runs in the cloud Smart escalation — a gentle nudge first, then your group, then a friendly automated wellness call if you still haven't replied "I've got it" — the first person to respond stops the reminders for everyone else, so your circle stays coordinated, not panicked Medication reminders — gentle nudges at the right times, and your family can be let know if a dose is missed Share location & a photo — add your map pin and a moment from your day when you check in One-tap group alert — reach your whole circle instantly with your location, all at once Sealed Vault — keep private notes end-to-end encrypted, shared with your circle only if you're ever out of reach for a long time Live group view — see your loved ones' check-ins in real time Multi-language — messages arrive in each person's own language Privacy-first — no constant GPS tracking; you choose what to share, one tap at a time Why Tether Me is different Messaging apps reach you when you reach out. Tether Me reaches out when you don't. A missed message on WhatsApp means nothing — but a missed check-in on Tether Me means someone is gently let know to look in on you. It's the difference between staying in touch and never being forgotten. Because love is staying close — even when you're far apart.
