MD339 Digital watch face

Review by eFreeware

MD339 Digital watch face is a paid customization app from Matteo Dini MD Watch Faces. This one is a digital dashboard with a flight-inspired look, and it is built on the Watch Face Format that Google Play now asks watch faces to use. The main reason to consider it is that it packs weather, health readings and shortcut buttons into one screen without asking you to install anything extra.

It costs $2.99 as a one-time purchase. There are no ads and no in-app purchases, which keeps the experience simple: you buy it, apply it to your watch and customize it to taste. At the time of writing it has a 4.4 average from 484 ratings and more than 10,000 installs, with a release date of August 20, 2025 and an update in June 2026 that fixed a date-area image issue in the Wearable app and added a date display that rotates between the year and the month.

Who MD339 is built for

The app targets Wear OS smartwatch owners who want a dense, information-rich face rather than a minimal analog look. You need Wear OS 5 or newer, since it requires API Level 34. The developer lists Samsung Galaxy Watch 4 through 9, the Ultra and Ultra 2, the Pixel Watch and other Wear OS devices as compatible, so most current watches are covered.

If you like the idea of seeing the weather, your heart rate, step count and battery level at a glance, and you want to be able to change colors and shortcuts, this is the kind of face that rewards that interest. It is less suited to someone who wants a single-purpose face with one or two data fields. The dashboard is the point, and the design leans into that.

There is a caveat for older hardware. The developer notes that Galaxy Watch 4 and 5 devices may occasionally customize more slowly because of hardware limits and issues with the Wear OS companion app. If you are on one of those older watches, the face should still work, but the customization process may not feel as smooth as on newer models.

Weather on the wrist, no extra app needed

The weather integration is one of the strongest parts of the package. MD339 uses your watch's built-in weather provider, so you do not need to install a separate weather app for the face to show conditions. The face displays current conditions along with forecasts, and you can choose between daily forecasts for the next two days or hourly forecasts at +6h and +12h. Temperature units follow your phone settings, so Celsius or Fahrenheit appears automatically.

There is one known gap worth knowing about. A weather provider bug reported to Samsung and Google can block daily forecasts before 7 a.m. During that window hourly forecasts still work normally, so the face is not left without weather information entirely.

The weather shortcut behaves differently depending on the watch. On Samsung Galaxy Watches it opens Samsung Weather, while on some non-Samsung devices such as the Pixel Watch the shortcut may not be available at all. Even then, the weather data on the face itself continues to work. That is a sensible fallback, though it does mean the shortcut is not equally useful on every device.

Shortcuts, complications and health data

MD339 includes six preset app shortcuts plus one that you can assign yourself. The preset shortcuts cover Calendar, Battery, Heart Rate, Alarm, Steps and Weather. That covers the tasks most people reach for during a day, and the custom slot lets you add the one app you use most. The arrangement is straightforward: tap a shortcut, and the corresponding app opens.

Beyond shortcuts, the face supports up to three customizable complications. Other options include distance walked, calories burned, barometer readings, world clock, UV index and chance of rain. Some complication providers may require a third-party app on your watch, so the exact list you can use depends on what you have installed. That is normal for complications, but it is worth remembering if you expect every option to be available out of the box.

The health and status readings are built in. The face shows heart rate monitoring with intervals, steps with daily goals, a battery meter, and the date. The year and month alternate every six seconds, a dynamic display added in the June 2026 update. Time follows either a 12-hour or 24-hour format and syncs with your phone settings, so you do not have to set it manually.

Customization: colors, LCD styles and Always On modes

Customization is handled on the watch itself. You touch and hold the display, then tap Customize. From there you can change the colors of the time and date, the LCD colors, the complication fonts, the battery indicator color and the heart rate LCD color, and switch between light and dark themes. Multiple LCD styles change the character of the face depending on which you pick.

Always On Display is supported in two modes: Minimal and Full. That lets you decide how much information stays visible when the screen dims. A fuller Always On mode shows more data but draws more attention, while a minimal one keeps the display quieter. Since the choice is yours, you can match it to how you use the watch.

The customization options are broad for a single watch face, and they are the main reason the app can feel personal rather than generic. The trade-off is that there are many settings to work through, so the first setup may take a few minutes of tapping through menus. After that, changes are quick.

What it costs and what you get

MD339 is a one-time purchase of $2.99. Nothing in the app is gated behind a subscription or a further payment, and there is no advertising to interrupt the watch face.

That makes the value question simple: you are paying once for a customizable digital face with weather, health data, shortcuts and complications. Whether that is worth it depends on how much you care about having all of that on your wrist at a glance. For someone who checks weather and step counts throughout the day, the density is the appeal.

The price is in line with what paid watch faces typically cost, and the absence of ads or additional purchases keeps the experience uncluttered. The decision rests on whether the screenshots and feature list match what you want.

How it compares with other watch faces

The closest alternatives are other paid digital watch faces on the Play Store, many of which also use the Watch Face Format and offer weather, complications and color options. MD339 distinguishes itself with the flight-inspired dashboard look and the specific mix of six preset shortcuts plus one custom slot. If that aesthetic appeals to you, it is a reasonable choice among similar paid faces.

Another alternative is a free watch face with fewer features. Free faces may not offer the same level of customization. MD339 is a paid app, which is part of what the $2.99 buys. If you are comfortable with a simpler face, a free option may be enough.

A third comparison is a dedicated weather app or a health app that shows data on its own screen. MD339 brings that information onto the watch face itself, so you do not have to open another app to see it. That convenience is the main argument for choosing a face like this over separate apps.

A dashboard for Wear OS owners who want it all on one screen

MD339 is a well-rounded digital watch face for Wear OS 5 and later. It combines weather forecasts, heart rate, steps, battery and date into a single dashboard, and it lets you customize colors, LCD styles, shortcuts and complications. The $2.99 price is a one-time cost with no ads or in-app purchases, and the 4.4 rating from 484 users suggests that most people who bought it are satisfied.

It suits Wear OS owners who want a lot of information visible at once and who enjoy tweaking colors and layouts. If you are on an older Galaxy Watch 4 or 5, expect customization to be a little slower, and be aware of the early-morning gap in daily weather forecasts. Those are minor caveats rather than reasons to avoid it.

If you prefer a minimal face or you do not need weather and health data on your wrist, a simpler option will serve you just as well. For everyone else, MD339 is a solid, customizable choice that does what it says.
