Comments on Simurelay for Android

★★★★★ Derpy Hooves (L.F.) · Nov 21, 2025

To the developer, I hope you add new parts to the system such as running capacitor and starting capacitor for three-phase training connection

★★★★☆ Rahul Maurya · Oct 5, 2025

Really a good platform for simulation of an electrical circuit, but Export and import features are available in the paid version, and the price is so high, if anyone purchased it they can only use it in the same device if he wants to move on any other device (it may be there device has any type of faltu or anything else) there paid version will not be with them, so please add an account option in it, and if possible please reduce subscription price around 299 or less, and ACB feature and there kit

★★★★☆ Prashanth R · Feb 13, 2026

Please add components like a voltage monitor current monitor voltage CT and for both single phase and three-phase

★★★★★ Francois Scholtz · May 29, 2026

Wish it can make use of PLC and rotation on signal phase motor. But the rest is really helpful

★★★★★ Willie ll J Emmanuel · Mar 17, 2026

This app is great. The only problem with it in my country is that, it's not allowing me to pay for the full version. I need to use the timer functions. Good morning from Liberia

★☆☆☆☆ Mark christian · Jan 19, 2026

I have already purchased all new features, but the timer didn't work. Very disappointing

★☆☆☆☆ Innocent Soka · Mar 23, 2026

In this new version contactor coil is nowhere to be found the available coil is just impulse coil, solenoid coil, which you can't control contact in motor

★☆☆☆☆ jerwyn ragandap · Jul 14, 2025

It updated, and I lost all my projects, it was 4 separate projects that was just lost. Sliver lining UI is way better than before. I still lost projects and my time became meaningless

★☆☆☆☆ Dr Norman Osborn · Dec 30, 2025

Its good app, but I can't use Off Delay Relay. It's not off and still on. On Delay Relay is work alone but not with many components. My phone is Android 10. Realme 5i. Plz fix it. I've purchased all features.
