All Android mobiles come with a preinstalled phone application. If you are not too convinced, your alternatives go through Google Phone and a multitude of alternatives of questionable quality. Koler is much simpler, lightweight and also completely free, ad-free.
Koler is an open source phone app that you won’t find on Google Play and is kind of a breath of fresh air for the have a somewhat different interface
A ph one application with the basics and nothing more
Koler is a simple and minimalist Android phone app that takes up around 10MB of memory. Unlike other similar apps, this is not a clone of the AOSP phone app or includes a bunch of extra things like an invasive caller ID system. Do the basics, nothing more.
Its interface literally has two sectionswithout even having a screen for settings. On the one hand the contacts view and on the other hand the recent view, which displays the call history. The grace of the matter is that the list has a nice design which is complemented by animations (which you can turn off, if they don’t convince you).
As expected, you can use Koler to make and receive calls – with the prior authorization of the required permissions – and with an interface that doesn’t distract you
Although few in number, the application does include a few options in the menu, including managing blocked numbers, choose accent color, activate compact mode or ask which SIM you want to use, on a Dual SIM mobile.
In short, it’s a simple phone application for those who are not looking for anything eccentric. The app is not available on Google Play, but you can install it from its APK directly from GitHub. Requires Android 7.1 minimum.
