Use this app to connect to a Z21 Digital Center. A demo mode is available. With this app you can manage locomotive libraries, locomotives and locomotive functions, program digital components – and of course control all locomotives with DCC- or Motorola-decoder, as easy and convenient as is only possible with touch-technology. The digital switchboard Z21 connects your model train unit and your digital locomotives with your iOS device via WLAN. This way you can control the operation on your train layout easily and conveniently from your mobile device. Model train control was never this easy and convenient: With one swipe of your hand you can scroll to your model of choice in the locomotive library. A slight touch on the headlight symbol and the front and backlights go on. A second touch, this time on the speaker symbol, and the locomotive makes a sound. Drag your finger over the speed indicator and the train accelerates. The further highlights of the Z21-Mobile-App • Control your entire layout with an intuitive, graphic interface and have easy access to the entire scope of functions of your digital locomotives. • Manage your entire locomotive-library in just one application, including individual locomotive images for an ideal overview. • Control the digital functions of your locomotives with intuitive function symbols instead of complicated key combinations.

Verdict
The clearest difference is rating: Win at 5.0 against Z21 mobile's 4.4. Win also leads on review sentiment (86% vs 50%). Z21 mobile's advantage is update cadence (every 2 months vs every 18 months) and ratings volume (5 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Win holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Z21 mobile has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 86% of Win's written reviews are positive against 50% of Z21 mobile's.
Win ships an update every 18 months, Z21 mobile every 2 months. Both last shipped on October 11, 2026.
