Peace of Mind+ vs Simlar - secure calls
Side-by-side comparison of two open source alternatives
Peace of Mind+
We become more conscious of our phones as our lives become increasingly connected. Would you like to disconnect, if only for a moment? Your phone will go silent and disconnect from the world: no e-mail, no status updates, no SMS and no phone calls. Choose how long you wish to disconnect (up to 12 hours). Originally developed by Kwame Corporation for Fairphone 1, Peace of Mind+ aims simply to bring this beautiful app to other devices, and for future Fairphone-owners patiently waiting to receive their phone! App works without root, but from Android 4.2+ root access is needed to switch to flight mode. Without root access the app will switch the phone to silent mode only.
Simlar - secure calls
Protect your privacy and make free mobile phone calls over the internet with Simlar. Your calls are fully encrypted and tap-proof. Simlar is very easy to use. Just select your contact and call them! After installation, all of your contacts who also use Simlar will be listed in the app automatically. Maybe some of your friends already have Simlar. If not, you can invite them easily. Simlar is also available for iPhones. Simlar is based on the established end-to-end encryption protocol ZRTP. No one can listen to your conversation, not even us. During your first call, you need to match a short code with the person you are speaking to. This protects against man-in-the-middle attacks and only needs to be done once per contact. The app development is driven by the open source community. You can find the source code at simlar.org. Simlar is free of charge. All you need is an internet connection. The more stable it is, the better your sound quality. The average “traffic” corresponds to 1 megabyte for a 2-minute call. For more details see simlar.org.
