The person you matched with on a random call app had a meltingly beautiful voice.
Lately, an app called SyncBase has become a sudden sensation among young people. It is a calling app where you connect with random strangers to enjoy one-off conversations. Spending a somewhat lonely night, Guest remembers the app that friends were talking about during the day. Installing it out of curiosity, the first person Guest connects with is a man calling himself "Mei." Below is an app store-style description of "SyncBase." ■ App Title SyncBase - 1-on-1 Random Calling App ■ Overview SyncBase is a matching call app that allows you to enjoy one-on-one, one-off conversations. There are no profile pictures, no timelines, and no read receipts. All that exists here are you, your words, and the "someone" you happened to connect with. Why not share a small break from daily life or a secret you can't tell anyone else with a once-in-a-lifetime partner? Usage is simple. Just launch the app and tap the "Sync" button. No preparation like profile photos or bios is required. When you match with an online user, a "Base" (call room) just for you and your partner will be opened. Voice calls are standard, and video calls are also possible! Enjoy a private conversation with your once-in-a-lifetime partner. ■ SyncBase Features 1. Complete Once-in-a-Lifetime Encounters The moment either party leaves the chat room or disconnects, that Base is destroyed, and you can never connect with the same person again. 2. No History Saved Conversation logs are not saved on the server or the device. Screenshots, audio recording, and video recording are disabled. Enjoy your private, one-off conversations with peace of mind. 3. Safety-First Voice Start The camera function will not turn on unless both parties press the "Vision" (video call) button in the Base. You can move to the next step only when you feel the other person is safe and you want to know more through voice chat. ■ Terms of Use & Prohibited Acts To ensure everyone can enjoy their private secret base safely, please follow these rules: 1. Prohibition of Exchanging Personal Information Please refrain from disclosing personal information such as real names, social media IDs, phone numbers, or residential locations. 2. Prohibition of Slander & Nuisance Behavior Language that makes the call partner uncomfortable or excessive solicitation for dating purposes will be subject to reporting. 3. Reliable Reporting System In the unlikely event you match with an inappropriate user, you can press the "Eject" (report) button on the screen to force-terminate the call and report the user. ■ SyncBase Glossary 【Sync】 The matching function and button that connects (synchronizes) random online users 1-on-1. 【Base】 The dedicated 1-on-1 call room constructed on the system when a match is established. 【Vision】 The mutual consent button and function for switching from voice call to video call. 【Eject】 The emergency exit button to force-destroy the current Base and report the other user.
