About

Skept

Read full description

The β€œofficial” Skept app for connecting to the Skept engine. Skept is an old-school social hive engine, inspired by how online communities and social media used to feel. The engine originally started out as DiodeMatrix Workspace in 2018, a platform used to develop software and experiments. In 2021, it was turned into a hobby-project β€œfork”, as they call it, so the system wouldn’t get lost and could continue as a community project.

Half game, half chat. Seven questions a day, the same for everyone: answer, guess what share of people answered like you, and from 21:00 see how well you read them. Then talk with other players in rooms for your game and language, or one to one. Each time you open SYNC, you choose a half. THE GAME Most of the time your guess is wrong. That is the whole point. - Seven questions land at midnight: how you hang the toilet roll, whether you rinse pasta, what you would do with a wallet you found - Tap your answer, predict the split, and change your choice until you tap β€œLock it in” - From 21:00, once the reveal is published, your summary is free: majority, minority or split, how close your guess was, your streak and day grid - Wednesday is Civil War day: one question that splits people close to fifty-fifty - Duo: after your first viewed reveal, invite one person and guess each other - The deeper answers are never shown next to your name, to anyone THE PLAYER CHAT (ADULTS ONLY) The chat is the same in every Erek Studio game that has it: one account, made with Sign in with Apple, for adults only (18+, 19+ in Korea). The questions need no sign-in. - Rooms for each game and language, and one-to-one messages; a first message from someone new arrives as a request - You choose who to talk to: there is no matching - Report or block anyone from their message or profile; what you report is hidden for you at once - Messages are checked for safety by Anthropic's AI; you agree to this before you join - Text only, no photos or links; a profile photo comes with Chat+ and is checked by AI before anyone sees it - With notifications on, you know when a message or a chat request arrives; they never show what it says - In Korea, the chat is SYNC's Korean room, and one-to-one messages go only between people who both wrote there - Delete your chat account in the app at any time SYNC PREMIUM AND CHAT+ SYNC Premium adds exact percentages with 20+ answers, your region vs the world when comparable data exists, calibration and rarity detail, Editors vs you where an editorial guess is available, week and month numbers when there is enough history, and every day you have played in the archive. SYNC Premium is an auto-renewing subscription, monthly or yearly. Eligible new subscribers can try its yearly plan free for 7 days where offered. Chat+ is an auto-renewing subscription, monthly or yearly. Bought in SYNC, it also gives everything SYNC Premium gives. In the chat: - Unlimited direct messages - Looks and a profile photo - Contact sharing: only in an accepted one-to-one chat, once the other person has written 3 times; they can turn it off. Never in rooms or profiles - Outside Korea: create your own rooms, public or invite-only, and find players by country and language Chat+ works in every Erek Studio game where you sign into the chat. Bought in SYNC without a chat account, it unlocks SYNC's perks on this device; signing into the chat later moves it to your account. Restore purchases brings back both. Payment is charged to your Apple ID when you confirm the purchase, or after an applicable free trial ends. Subscriptions renew automatically at the same price unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel them anytime in your Apple ID settings.
