Mahlkönig Home

The hopper problem nobody mentions

The X54 Allround Home Grinder is an on-demand machine. This means you fill the hopper with beans and grind what you need. Switching beans or brew methods mid-bag requires a purge. You must grind and discard a small amount of coffee to clear the old grounds from the burrs. This adds waste and friction, especially for households that rotate between espresso and filter coffee. The app does not solve this. It cannot. The physical design of the grinder dictates this behavior. The app simply reports what the grinder does. It shows you statistics, but it cannot change the fact that single-dosing is not the X54's strength.

The plastic chassis is another point of contention. For a grinder that costs over $500, the predominantly plastic body feels mismatched against the Mahlkönig badge. Competitors at this price point often offer aluminum or steel casings. The app does not address this either. It is a software layer on top of a hardware device that has certain physical limitations. Users who expect a premium tactile experience may find the plastic housing disappointing. The app's interface is clean and functional, but it cannot compensate for the grinder's material choices.

These limitations are not deal-breakers for everyone. Many users accept the purge requirement as a trade-off for the grinder's consistency and quiet operation. But they are real constraints that any potential buyer should know before downloading the app. The app is free, so the cost of entry is zero. But the grinder itself is a significant investment. Understanding its quirks is essential.

The recipe system that actually works

The app's core strength is its recipe management. You can create, edit, save, and delete grinding settings as recipes. Each recipe stores a specific grind time. The X54 has four programmable time presets on its display. You assign recipes to these slots directly from the app. This means you can have one preset for espresso, one for pour-over, one for French press, and one for cold brew. Switching between them is a single button press on the grinder. The app makes the setup process straightforward. You name the recipe, set the grind time, and assign it to a slot.

The Dial-In assistant is another useful feature. It provides step-by-step instructions for dialing in your grind size. You select your brew method — espresso, pour-over, French press, or others — and the assistant guides you through the process. It suggests starting points and tells you how to adjust based on the results. This is helpful for beginners who are not familiar with the nuances of grind size adjustment. The X54 has a stepless adjustment mechanism with no clicking sounds. You turn the dial continuously. The app helps you find the right setting without guesswork.

Statistics tracking adds another layer of utility. The app records the number of shots you pull, the total grinding time, and the usage of the grinder's burrs. This data helps you monitor wear and plan for maintenance. The motor is rated for over 25,000 shots, but knowing how many you have actually used is useful. The app also supports firmware updates. You can update the grinder's software directly from your phone. This ensures you have the latest features and bug fixes.

From login to grinding: the workflow

Setting up the app requires a few steps. First, you download it from the Google Play Store or Apple App Store. The app is free. You open it and it searches for nearby X54 grinders. The grinder creates its own WiFi access point. You connect your phone to that network. The app then pairs with the grinder. Once paired, you can see the grinder's status on your phone. The display shows the current settings, the recipe slots, and any available firmware updates.

Creating a recipe is simple. You tap the plus button, enter a name, set the grind time, and save it. The app sends the recipe to the grinder. The grinder stores it in one of the four slots. You can also edit or delete recipes at any time. The app syncs changes automatically. Sharing recipes is also possible. You can send a recipe to a friend who also has an X54. This is useful for sharing your preferred settings for a specific coffee bean.

The Dial-In assistant is accessed from the main menu. You select your brew method and the assistant walks you through the process. It tells you to grind a sample, evaluate the results, and adjust the grind size accordingly. The assistant tracks your adjustments and helps you converge on the optimal setting. This is particularly useful when you switch to a new coffee bean. Different beans require different grind sizes. The assistant removes the guesswork.

One specific interaction: recipes and time presets

Consider how the recipe creation and the four grind-by-time slots work together. You create a recipe for espresso with a grind time of 18 seconds. You assign it to slot 1. You create another recipe for pour-over with a grind time of 12 seconds. You assign it to slot 2. On the grinder's display, you can now select slot 1 or slot 2 with a button press. The grinder grinds for the programmed time. This workflow is efficient because you do not need to adjust the timer manually each time you switch brew methods. The app stores your preferences and the grinder executes them.

The limitation emerges when you want to use a recipe that is not assigned to a slot. The grinder only has four slots. The app can store unlimited recipes, but only four can be active on the grinder at any time. If you have five favorite recipes, you must swap one out. This requires opening the app, assigning a different recipe to a slot, and waiting for the sync. It is not a major issue, but it is a constraint. The app's unlimited storage is useful, but the grinder's hardware limits how many recipes you can access directly.

This interaction between the app's unlimited storage and the grinder's four-slot limit is a practical reality. The app gives you flexibility, but the grinder imposes a ceiling. Users who frequently switch between many brew methods may find this limiting. The app does not hide this limitation. It is transparent about the four slots. But it is worth noting that the unlimited storage is not unlimited access. You must curate which recipes are active at any given time.

The changelog situation

The Play Store listing shows a changelog entry of "Minor bugfixes." The iOS version history lists similar entries: "Minor bugfixes" for version 1.3, "Bug fixes" for 1.2, and "Bug fix dial-in assistant" for 1.1. The developer has not published detailed release notes. This means users do not know exactly what changed in each update. The updates could include performance improvements, new features, or security patches. The lack of transparency is a common issue with many apps, but it is still a gap.

The app's version number, according to third-party sources, is 1.7.5 for Android and 1.3 for iOS. The last update for Android was on February 26, 2026. The iOS version was updated more recently. The developer, Hemro International AG, is based in Switzerland. They have a privacy policy available on their website, but they do not provide a detailed changelog. Users who want to know what changed must rely on third-party sites or community forums. This is not ideal, but it is the current state of affairs.

The final technical detail: data sharing and permissions

The app's data safety section on Google Play lists several categories of data that may be collected. These include location, personal information, app activity, app info and performance, and device ID or other ID. The app states that data is encrypted in transit. On the iOS side, the privacy practices indicate that usage data may be used to track you across apps and websites owned by other companies. Location data and usage data are collected but not linked to your identity. The app does not share data with third parties, according to the Google Play listing.

The permissions requested by the app are not fully listed in the snippet, but the data safety label indicates that location and personal information are involved. The app requires WiFi access to connect to the grinder. It also needs storage permissions to save recipes and settings. The app is free, with no in-app purchases or subscription tiers. The developer is Hemro International AG, based in Zurich, Switzerland, with contact information available on their website. The app is designed exclusively for the X54 Allround Home Grinder and does not work with other grinders.
