In short
Choose IsolaDesk if…
You handle three WhatsApp numbers or more on a computer, which is where a phone with two accounts stops being enough, and you want an app made only for that: every number in its own isolated workspace, notifications that name the workspace, up to four side by side and an app lock with a passcode, or Touch ID on Mac.
Choose Ferdium if…
You want a free, open-source app, you also use other messaging services in the same window, or you work on Linux or FreeBSD.

What the table doesn’t show
Two different jobs
Being free and open source is a real advantage of Ferdium, and we don’t compete on price. IsolaDesk does less on purpose: WhatsApp only, an Overview of every number’s unread messages, notifications per workspace, an app lock with Touch ID, and email support from a company, with a refund on your first payment.
Memory with several accounts
Each WhatsApp account open on a computer uses memory, whatever the app. We will publish a measurement of IsolaDesk with six accounts open, made on a real Mac; until then, we quote no number. IsolaDesk can also put inactive workspaces to sleep.
Privacy
The app has no analytics and no advertising. Your messages go directly between your computer and WhatsApp; our license server only receives your license key, a pseudonymous device ID, your computer’s name and the app version. Security details
