Illustration of WhatsApp’s tested floating bottom bar and birthday reminders in the Contacts tab.
WhatsApp is testing a redesigned bottom navigation bar on Android, with a floating look and rounded corners, as part of a wider cluster of changes that are still in beta or rolling out selectively across platforms. The same run of updates includes birthday reminders in the Contacts tab, where saved birthdays from a phone’s address book appear next to contacts, giving users a new prompt inside everyday messaging workflows. For business users who manage customer or team communication in WhatsApp, the practical shift is straightforward: more of the app’s routine follow-up, sharing, and response tools are moving closer to the main chat flow.
Android’s floating bottom bar and the new Contacts-tab reminders
The Android redesign is the most visible interface change in the current batch. WhatsApp’s beta version is testing a bottom navigation bar that no longer sits as a flat strip, instead using a floating treatment with rounded corners. It is still under development rather than in broad release, so the layout could change before wider availability. Even in that early state, the goal is clear: make the main navigation feel more distinct and easier to reach during frequent switching between chats, calls, communities, and updates.
The more practical utility change sits in the Contacts tab. WhatsApp is testing birthday reminders that pull dates from birthdays already saved in the phone’s address book, rather than asking users to enter them again inside WhatsApp. Those reminders appear beside saved contacts, which could help operators and small teams catch personal follow-ups without leaving the app to check another contact manager. For users who already keep contact records updated on their phones, that makes WhatsApp a little more useful as a daily relationship-management tool.
Custom reactions and the five-agent cap on iOS
On the account side, premium users on iOS and Android are gaining a more flexible reaction tray. Instead of being locked to WhatsApp’s six default reaction emojis, they can swap those defaults for custom emoji reactions. The packaging around that premium access is not fully clear, but the functional change is: reactions become more tailored, which matters for teams that use emoji responses as quick workflow signals rather than casual replies.
WhatsApp is also rolling out chat access to third-party agents on iOS, with support for up to five agents per account. That cap is the clearest operational detail available right now, and it sets a hard limit for anyone considering the feature for support or routing use cases. What remains unclear is how those agents are hosted or configured, so the immediate takeaway is narrower: iPhone users are getting a multi-agent option, but only within a five-agent ceiling.
Instagram and Facebook sharing move closer to WhatsApp workflows
Another change connects WhatsApp more directly with Meta’s other consumer apps. Through Accounts Center, WhatsApp is adding sharing from Instagram and Facebook into both chats and status updates. That gives users a more direct path to move stories, posts, and reels into WhatsApp conversations without rebuilding the share step by hand.
For business operators, that could trim friction when moving campaign content, product posts, or social updates into customer threads and broadcast-style status posts. The exact presentation of that shared content is still unclear, so it is too early to say whether recipients see links, previews, or embedded media. But the core workflow shift is already visible: WhatsApp is being tied more tightly into cross-app sharing, not treated as a separate endpoint after the fact.
ZapFast shows the demand for a lighter desktop companion
Alongside WhatsApp’s own mobile changes, a separate desktop-side project highlights a different user demand. ZapFast is an independent WhatsApp companion client written in Rust with egui, and it avoids using a browser engine entirely. It is not an official WhatsApp or Meta product, but its pitch is easy to understand for anyone frustrated with heavy desktop browser setups.
In its Linux benchmark, ZapFast says it opens in under one second and uses about 150 MB of idle RAM, compared with 1.13 GB for WhatsApp Web plus Chromium processes. It also supports a fuller set of chat-management tools than a bare companion app, including pinned, unread, muted, and archived chats, filters, favorites syncing, channels, search panes, and up to three pinned chats. The app links to a phone as a companion device and stores local history after linking, which makes it feel closer to a native desktop workspace. Even though it sits outside WhatsApp’s official product line, it underlines a live need that Meta’s own desktop experience has not fully solved: a faster, lighter companion for people who spend all day in WhatsApp.
