i made sundial because i wanted a quiet, and secure place to connect with my friends. technology and other apps today are so loud with ads, ai reels, and other bs and i just wanted a place where i could slow things down and chat with the people i actually want to talk with. it's private from the start. you add your friends yourself, by sending your link or holding your phones together, and nobody sees your chats because everything is encrypted. · golden hour: once a day at a random moment, sundial tells your whole continent at once. you get an hour to beam your picture, and your friends' open once yours is out. · chats: everyone you talk to one to one is a moon around your earth. · group chats: your groups are solar systems, three to eight of you, floating in your universe. tap one and fly right in. · music: beam a song or trade them through your favorite music platform. every chat keeps a mixtape of everything you've shared, and with sundial gold you can queue songs in the dj booth and listen along together. · facetime: pick a time to call from any chat. in a solar system, one tap opens the room and pings everyone to hop in. · draw: sketch them something by hand. · and more: photos and stacks from your camera roll, 15 second videos, hums, flares, a sunday film of your group's week, and moonflowers that bloom on a night you pick. · your messages, photos, videos, voice notes and golden hours are end to end encrypted on your phone before they leave it. only the people in your chat, and your friends, can view them, unless one of them reports it. · your page isn't: anyone with your link sees your name and your profile photo. the privacy policy at sundialus.com/privacy has the rest. · we never ask for your email, phone number or contacts, and you can block or report anyone. · no ai slop, no feed, no followers, no unwanted ads, nothing built to keep you scrolling. · no bs subscriptions, you own it. i hate that junk trust me. ty for taking the time to read this and look into my app. it really means a lot to me that you're here. if you want to read more about the mission of sundial you can here sundialus.com built by one person in various coffee shops, now yours too.
