Spike is a dialog-based email app, designed primarily as a collaboration tool but also works well as a high-quality WhatsApp alternative, thanks to its group-oriented chat feature. Developed by an Israeli software company, the classic email inbox is transformed into a modern dialog platform that doesn’t require complicated mail elements like subject lines or signatures. Your own email account remains the primary fixed point, which is why registering with Spike doesn’t require you to provide a personal phone number, unlike many other apps like WhatsApp.
Groups chats on Spike are much like WhatsApp group chats. They can be created instantly, and any other Spike users can be added to a group. Again, the only requirement for use is providing an email address. After joining a group, all members can exchange real-time messages that can be read by everyone. You can create as many groups as you want, however there is a limit of ten groups in the free basic version.
Of course, you can also exchange one-on-one private messages with Spike in either text form or as voice messages. Additionally, Spike can be used to make video calls. The Spike team really prioritizes data protection, which is why all data is automatically encrypted before transmission using AES-256 and is stored encrypted on the servers. Each message receives its own unique key.
One of the biggest advantages Spike has is that the communication tool can be used, not just through the cross-platform web app but also through native apps for iOS, Android, Windows, and macOS. Once the account is set up, private and group conversations can easily be tracked and held from any device. All versions of Spike are free for private use – anyone wishing to use Spike commercially must subscribe to a paid monthly subscription.
