Doptyn is the social app built for gym people โ not a generic feed with a fitness filter on top. Everything revolves around your training, your gym, and the people grinding alongside you. SHARE YOUR TRAINING Post photos, upload 60-second dops, and drop 24-hour stories straight from your session. Tag your gym, tag your friends, and add music, text, and filters in the in-app editor. TRACK YOUR CONSISTENCY Build a daily streak across every post, story, and reel. Set a consistency challenge โ 30, 45, 75, 180, or 365 days โ and watch the ring fill. Showing up is the whole game. SHOW YOUR PROGRESS Post before-and-after transformations with a highlight reel and let your hard work speak. Save the posts that inspire you into folders. FIND YOUR PEOPLE See who's training at your gym right now, discover lifters near you, and connect with the community that actually gets it. Follow friends, gyms, and trainers. MATCH WITH GYM-GOERS Open to dating? Swipe and match with people who share your fitness lifestyle. Find a training partner or something more โ with people who'd rather hit the gym than sit at a bar. CHAT IN REAL TIME Message your matches and friends, react, reply, share reels, and send voice notes. Group chats for your crew. Vanish mode and view-once for the stuff that's just for now. FOR GYMS & TRAINERS Gyms get their own profiles, post their own content, collaborate with creators, and show off their community. Trainers can list affiliations and specialties. DISCOVER An explore feed organized the way you train โ Push, Pull, Legs, Abs, Cardio, Crossfit, Bodybuilding, and Meals โ so you find content that matches today's session. Doptyn is free to download. You must be 18+ to join.
Knock

Knock is a messenger built on one idea: nothing happens without your yes. No phone number. No SIM. Your identity is a handle you choose โ share it with the people you want, and only them. CONSENT FIRST Nobody can message you, add you to a group, or even see you without knocking first. Every connection starts with a request you can accept or decline. Group adds work the same way โ no more waking up in a group you never asked to join. REALLY PRIVATE โข End-to-end encryption on every message, photo, file and voice note โ the server only ever stores ciphertext. โข Optional App Lock: require your fingerprint, face or PIN to open the app, with screenshots and the recents preview blocked while it's on. โข No ads, no tracking, no analytics SDK, no contact-list upload. Crash reports are off unless you switch them on, and never include your messages. โข Notifications tell you who wrote, not what they said โ the push that wakes your phone carries no message content at all. ON YOUR TERMS โข Attention controls per conversation: Normal, Mentions only, or Quiet. โข Schedule messages to send later โ anything up to 24 hours out. โข Personas: keep work-you and personal-you as fully separate identities in one app. โข Single-tick receipts by design โ read status is yours to give, not taken. SAFETY โข Block anyone, from their name in a chat or while reporting them. Blocked people can't reach you, and you can unblock from Settings. โข Report a message to our moderators in two taps. EVERYTHING YOU EXPECT Groups, replies, forwards, reactions, edits and deletes, photos, videos, documents with inline PDF preview, voice notes, QR connect, dark mode, and encrypted account recovery with email fallback. YOURS TO LEAVE Delete your account from inside the app, any time. It erases your profile, your email and the messages you sent โ permanently, with no support ticket to raise. BUILT FOR BUSINESS TOO Verify a work email domain to show a verified-business badge on your profile, so customers know they're talking to the real you. Knock is built on the open Matrix protocol. All you need to sign up is a handle, a password, and an email address to verify it.
