Choosing a WhatsApp Alternative: A Checklist for Privacy and Practicality
Switching messenger is easy. Getting your friends to switch is hard. This checklist helps you choose an alternative that is private enough and practical enough to stick.
A good messenger is one your friends actually use. A perfect one that nobody joins is worthless. That is why choosing an alternative is less about finding the most secure app on paper, and more about finding one that is private enough, easy enough and different enough to make people move. Use this checklist to compare any messenger, including the one you use today.
1. How is it encrypted?
The most important question. Ask: are messages end-to-end encrypted by default, in one-to-one chats and in groups? If only some chats are encrypted, or you have to switch it on, most of your conversations are not protected. In PeerFlow, chats and groups are end-to-end encrypted by default. See end-to-end encrypted chat explained.
2. What does it need to sign up?
Phone number, email, nothing at all? A phone number ties the app to your identity and invites contact scraping. Email is lighter, and a username lighter still. Read private messaging without a phone number.
3. Does it read your address book?
Apps that upload your contacts to find friends also upload other people's numbers without their consent. Prefer an app where you add people yourself.
4. Where do messages go?
Do they travel through the company's servers and stay there, or go directly between devices? How long are undelivered messages kept? See how messages travel.
5. Where is your history?
Is it on the company's servers, or on your device? Can you back it up yourself? PeerFlow keeps history encrypted on your device and lets you keep an encrypted copy in your own folder. See chat history backup.
6. Does it do calls and files well?
A messenger that cannot call, send a large file at full quality or share a screen sends you back to other apps. Check that voice calls, video calls and files work, and that photos and videos are not squashed. PeerFlow also offers online meetings and screen sharing.
7. Does it work on your devices?
Phone and computer, and the platforms your friends use. PeerFlow has Android and Windows apps, and meetings and file sharing work in any browser, including on an iPhone.
8. Is it reliable?
Messages should arrive, calls should ring, notifications should show. Read about notifications on Android to check that you can set up the basics.
9. What does it cost, and who pays?
Free apps are paid for in some way: ads, data or a paid tier. Look at how the company makes money and whether that is compatible with your privacy.
10. Will your friends follow?
This is the real test. Does joining take two minutes? Can a friend try it without installing anything? Is there a reason to switch, beyond your personal preference?

How to move people over
- Start small. Pick one group, such as a trip or an event, and use the new app there.
- Give a reason. "It lets us send full-quality videos" works better than "it is more private".
- Make joining easy. Send them the download link and your username.
- Do not force it. Keep the old app for people who will not move, and be patient.
- Show, do not preach. A smooth video call sells the app better than an argument.
What you will miss
Every switch has costs: fewer people, different habits, features you liked. Decide which matter. If you need a feature that the new app lacks, keep both.
For businesses
If you talk to clients, consider whether you want to give them your personal number. A username-based app lets you keep work and private life apart. See communication for small businesses and WhatsApp alternative for client communication.
Try it
Install the Android or Windows app, add one friend, and run the checklist yourself.
Frequently asked questions
Can I use PeerFlow and WhatsApp side by side?
Yes. Many people keep their old messenger for family and use PeerFlow for private or work conversations while they move people over gradually.
How do I get my friends to switch?
Start with one or two people and one topic, such as a group for an event. Make joining a two-minute job and show them the benefit.
Does PeerFlow need my contacts?
No. You add people by email or username, and PeerFlow does not read your address book.
Are calls and files included?
Yes. Voice calls, video calls, file sharing and group chats are part of the app.
