Peron vs the SŽ app: which one tells you your train is late?

The SŽ app, Grem z vlakom, is where you buy your ticket. Peron is where you watch your train. You'll probably want both on your phone, and this page explains why.
What each app is for
Grem z vlakom is Slovenske železnice's official app. You search the timetable, buy a ticket with a card or Moneta, show it to the conductor, and check notices about delays and replacement buses in a separate tab (App Store, SŽ help page). If you need a ticket, that's the app to use.

Peron does the other half. It follows the train you take, checks it every 30 seconds and tells you only when something changes for you: the train is 10 minutes late, it's time to leave home, your platform, a replacement bus. The rest of the time it stays quiet.
The railway has to run hundreds of trains, crews and buses. Peron only has to care about yours.
What you get with Peron
- Your train, watched. Set the train you take most weekdays once. Peron alerts you when it runs late by more than your threshold (10 minutes by default).
- When to leave. A leave-now alert that counts back from your train and your walk to the station, and moves when the train runs late.
- Every train on one map. Every passenger train in Slovenia, live. Positions between stations are estimates, and Peron says so.
- Your platform before the board. Predicted from where the same train stopped before, and labelled Predicted until it's certain.
- Changes that hold. For a journey with a change: the minutes you'll have, the minutes you need, how often that change has worked, and a plan B.
- On the Lock Screen. Your trip in the Live Activity and the Dynamic Island: next stop, arrival, delay.
- Rail passport. Every confirmed ride stamps your passport with stations, lines and kilometres.

Questions
Do I still need the SŽ app? Yes, for tickets. Peron doesn't sell tickets, handle refunds or lost property. Keep Grem z vlakom for that and use Peron for the trip.
Is Peron made by SŽ? No. Peron is independent and not connected to Slovenske železnice. It uses Slovenia's public timetable and real-time data.
Are Peron's delays the same as SŽ's? They come from the same public real-time data. Peron's job is to tell you sooner, and only about the trains you care about.
Which one should you use?
Keep Grem z vlakom for your ticket. Use Peron to know whether you need to run.
Know before the board does.
