Threema 是一个流行的安全通讯软件，它由瑞士团队研发，专注于个人隐私。 它也是一个付费软件，你需要在 Play Store 或者 App Store 上，一次性支付费用（大约 4 美元），才能够在你喜爱的移动设备上使用它。 起初，它是一个专有的安全通讯软件，是 Signal 等其他软件的竞争者。 在 2020 年的时候，Threema 决定在 GitHub 上开源它的所有软件。 你可以下载到移动应用，也可以得到 Linux 桌面（包括 Windows 和 macOS）上的支持。 遗憾的是，它在桌面上目前没有独立的客户端。 因此，你需要让移动设备保持开启状态，才能使用桌面上的 Threema（就和 WhatsApp Web 的工作方式一样）。 下面是你尝试 Threema 的可能理由.
