Comments on Simurelay for Android

★★★★☆ christian gader · Nov 18, 2025

The application is very functional and meets most of my design requirements, but I would like to recommend an improvement regarding the overload protection device behavior. Currently, the software automatically increments overload device tags (e.g., F1, F2) and does not allow the user to manually rename or reuse the same identifier. In real electrical design, overload relays often follow project-specific naming conventions, and in some cases multiple devices may share the same tag based on the

★★★★☆ 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

★★★★★ Francois Scholtz · May 29, 2026

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

★★★★★ Biswajit Das · Jul 20, 2025

Some component like olr contact, phase sequence relay contact, earthing are missing in new update. Timer contact and coil are not matching each other.

★☆☆☆☆ Quinton Jones · Apr 4, 2025

There are no English tutorials on YouTube. No support. The paid version is not really different from the free version. The latest version is not the same as what's on some of the tutorials (tried deciphering from Hindi Tamil or whatever Indian language the tutorials are in.

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

★☆☆☆☆ 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

★☆☆☆☆ Mark christian · Jan 19, 2026

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

★☆☆☆☆ 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.
