STF Fit

What STF Fit is for and who it suits

STF Fit is a companion app for STF smartwatches. It sends phone activity to the watch and shows health readings the watch has recorded, so the person wearing it can check calls, texts and fitness data without reaching for the phone. It is written for people who already own one of the supported watches.

The developer lists nine compatible models: the ZW01, T18, ZW27T, T100, T100A, L21, S050, T95 and G12Pro. The app's features depend on the watch being one of these, so the model number is the first thing to check against the listing.

Beyond the call and message alerts, the app also covers health tracking, daily reminders, a weather check and some display choices. Each is described in the sections below.

Calls and text messages on the wrist

When a call comes in, the app pushes a notification to the watch and shows who is calling. This is the main use for someone who keeps the phone in a bag or on a desk and still wants to know who is ringing.

Text messages are handled in a similar way. Incoming SMS messages are sent to the watch, where the text and its details can be read on the wearable screen. The listing does not describe replying from the watch, so the app should be taken as a way to read messages, not to answer them.

Heart rate, sleep and workout history

The app displays heart rate, sleep and workout history that the smartwatch tracks. The data is collected by the watch and shown in the app, which makes the history easier to scan than the small screen on most wrist devices.

Sedentary reminders sit alongside this tracking. They prompt the wearer to move after long periods of sitting, and the developer presents them as a way to help reach fitness goals. Together, the readings and reminders give a daily picture of activity and rest.

Reminders, alarm and weather for planning the day

The app includes a weather check, so the wearer can see conditions before deciding how to plan the day or when to work out. It is one of the few features the developer ties directly to scheduling outdoor exercise.

Two smaller tools round out the daily routine: an alarm and drink water reminders. The listing gives no further detail on how either is set or repeated, so the entries are best read as the features as named.

Watch faces and the supported watch list

The developer lists multiple watch face options, which lets the wearer change how the time and data appear on the watch. The listing does not name the faces or describe how they are chosen, only that the choice exists.

Because the app is tied to specific hardware, the nine supported STF models are the practical limit on who can use it. Owners of the ZW01, T18, ZW27T, T100, T100A, L21, S050, T95 or G12Pro are the people the listing is written for.
