Which one is for you
Pick Signal if

- Works for people who want no ads and no tracking
Look elsewhere if
- Skip it if you need a workplace tool, as it has no channels, roles or admin console
- Not for you if you want a desktop app on its own, since it needs linking from a phone
- Too light for support, because no paid or business tier is listed
- Watch out: no integrations or bots are listed, so it will not plug into your other tools
Pick Threema Work if

Look elsewhere if
- Tight if you have more than 200 users, as Core stops at 200

- Watch out: syncing users with Azure AD costs extra
- Watch out: the page converts CHF and EUR figures one-to-one into USD
- Watch out: self-hosting (OnPrem) is sold through sales with no published price

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
