The useful question is what changes for users, developers or buyers, and whether the announcement stays industry context or becomes something people can actually use.

A 2026 review of texting apps by Zapier identifies WhatsApp and Viber as leading options, focusing on criteria such as cross-platform availability, default end-to-end encryption, and support for multimedia and group chats. The evaluation excludes SMS and workplace tools like Slack or Teams, prioritizing apps that function across iPhone, Android, and desktop without carrier restrictions. The review underscores that the best app depends on which service contacts use most frequently, as adoption remains the critical factor in messaging reliability.

WhatsApp, acquired by Meta in 2014, remains a dominant global messaging platform with over three billion users. It offers core features like voice and video calls, file sharing, and group chats, all protected by default end-to-end encryption. Recent additions include Channels for broadcasts, AI integration, and plans for paid subscriptions, though these features have introduced clutter. Despite Meta’s monetization efforts, WhatsApp’s core messaging remains highly functional, supported by Zapier’s integration for business automation workflows.

Viber, another cross-platform option, provides similar messaging capabilities with standard end-to-end encryption for one-on-one and group chats. Its standout features include Communities for large public group chats and Viber Out for international calls at $5.99 per month. However, Viber’s interface is crowded with ads, stickers, and AI bots, detracting from usability. The app offers a free tier with optional Viber Plus for $1.99 per month to remove ads and add minor features, appealing to users seeking an alternative to Meta’s ecosystem.

The review tested over 30 apps, narrowing the list to six based on strict criteria: cross-platform support, privacy, no cost for core features, multimedia support, and group chat functionality. While no single app suits every need, WhatsApp and Viber emerge as top choices for most users. The evaluation stresses that security and ease of use are secondary to widespread adoption, as the most advanced app is ineffective if contacts do not use it.
