Few workplace tools inspire as much grudging dependence as Microsoft Teams. Bundled into Microsoft 365, it folds chat, video meetings, calling, and file collaboration into a single client, and for any organisation already living in Outlook and SharePoint it is effectively the default choice rather than a decision anyone made. There is also a genuinely free tier, which Microsoft has positioned as the home for personal calls and small groups since retiring Skype.
The Android app deserves scrutiny precisely because Teams follows people out of the office. Two things matter more on a phone than on a work laptop: how much of what you type is visible to your employer (more than most users assume, as we explain in the privacy section) and whether the notification volume leaves any evening intact. The app offers real controls for both, but the defaults consistently favour the organisation over the individual.
Working inside a Microsoft 365 shop
If your employer runs Microsoft 365, Teams ties chat to your Outlook calendar and SharePoint files with no extra setup. Joining a scheduled meeting from the phone, camera off, on a train, is where the mobile app earns its keep.
Free calls after Skype
The personal free tier handles video calls and group chats with nothing but a Microsoft account. Group meetings on the free plan carry a time limit, but for family catch-ups it is a serviceable Skype replacement at zero cost.
Frontline and shift work
Retail and healthcare deployments use the shift-scheduling tools and the push-to-talk Walkie Talkie feature, which turns the phone into a radio over Wi-Fi or mobile data. For workers without a desk, the mobile app is the whole product.
Chat and channels
Persistent one-to-one and group chats sit alongside channels, which organise team conversations by topic. Mentions, reactions, and message forwarding all behave as you would expect, though threading in channels still confuses newcomers arriving from Slack.
Meetings and calling
Video meetings support screen sharing, background blur, live captions, and joining by link without an account. Call quality on mobile networks is dependable, and handing a call from phone to desktop mid-meeting works better than it used to.
Files and Office integration
Documents shared in a chat live in OneDrive or SharePoint, so co-editing a Word file or reviewing a spreadsheet happens without leaving the app. This integration is the strongest argument for Teams over its competitors.
Quiet time controls
The mobile app can silence notifications during hours and days you define, on a schedule independent of your desktop. Setting this up on day one is the single best thing a new Teams user can do for their sanity.
