Is it good?

Well, as a top-performing app with an overall rating of 4.80 from 28 votes cast, I can safely confirm that It's good and worth trying. Here is what people say about Free42:

I have used the HP42s for years. Reverse polish is the way to go. Having lost one replacing it with another, I have now discovered this emulator and use it on every platform on which I operate. It is my primary windows calculator and my real HP42S stays at home.... I would recommend this to anyone who does any simple or complex calculations.
This app is just flawless. The HP-42S has been my favorite calculator for a long time, but thanks to this app, I no longer need to carry a priceless physical specimen around. The few issued I had with it in the past (e.g., no haptic feedback) have been fixed long ago.

A killer app by Thomas Okken

How it manages to be such a good tools app? Easy, I love how Free42 app is created to be a solidly built app with awesome features. Thomas Okken has successfully put efforts and engineered a sophisticated software. Try it for yourself, I am pretty sure that you will like it too.

Download Free42 APK for Android and install

I would love to guide you on how to download and install Free42 APK for Android in just five simple steps. But first lets have some basic knowledge of APK files. Android Package Kit is an Android application package file format used for distributing files and installing them on Android OS devices. Installing apps and games from APK file is a simple and straightforward process which you will remember forever when done once. It is a safe and working way to avoid restrictions made by developers for distributing apps in some geographical regions.

Step 1: Download Free42 APK on your Android device

Tap the blue button below and navigate to the download page. There you will choose the available download method.

Step 2: Choose the download method

Have in mind that some apps and games may not be available in Google Play for your country of residence. You can choose to save the APK file from Android Freeware mirrors instead of downloading the software from the Play Store. We are proud to serve your working mirrors 99.9% of the time.

Step 3: Allow installation of third party apps.

If you get an installation warning after starting the saved file, click Menu > Settings > Security > and check Unknown Sources to allow installations from this source! This has to be done only the first time you are installing an unknown APK file.

Step 4: Find and install the downloaded APK file

I suggest using a file manager app (MiXPlorer is my choice as robust and easy to use) to locate Free42 apk file. It is most commonly located in the Downloads folder. Open it now and proceed to installation (check out this How to Download and Install APK and XAPK files guide if you experience difficulties).

Step 5: Launch the app and enjoy

Start the installed Free42 app and enjoy it!

Is It safe?

I strongly recommend Free42 as good tools software. With over 227k+ and counting downloads, it is a safe app to download, install, and share with friends.

Note that the APK file can run on every popular android emulator. You can also send DMCA reports here.
