In their own words
imo
imo is a communication app for internet calls and messaging, available on Android, iOS, macOS, web, and Windows. It offers HD audio and video calls, including international calls, and group video calls for up to 20 participants with no fixed time limit. Chats support real-time messages, photos, videos, voice recordings, and group conversations; its Big Group feature supports up to 5,000 members. Stories hold photos, videos, and text updates for 24 hours. Listed privacy features include end-to-end encryption, Time Machine, and disappearing messages, while account controls include two-step verification and spam blocking. Encryption coverage is mixed. Instant message translation is available, and the privacy policy says Google Translate may provide it. That policy also says imo collects usage data, including communication partners, times, and message content. On iOS, imo integrates with Siri and can access iCloud Drive for file sharing. The app is free, though mobile carrier data charges may apply to internet calls.
Olvid
Olvid is an instant messaging app for text messages and attachments, available on Android, iOS, Linux, macOS, web, and Windows. Olvid says it does not require identifying details such as a phone number, email, name, address, or birth date. It also says messages and metadata are end-to-end encrypted, so it cannot know who is communicating with whom. Each message and file uses a single-use ephemeral key, intended to protect message history if a key is compromised. The app supports synchronization across devices without a master device. Secure audio and video calls are end-to-end encrypted; video calls support up to two contacts, while group audio calls have no participant limit. Receiving calls is free, and initiating them is free during a one-month trial that ends without billing or automatic subscription. The free plan includes unlimited messages and attachments, group discussions, ephemeral messages, multiple profiles, and inbound calls. Business costs €990 a year; Enterprise costs €990.50 a year.
