The Messaging Apps Worth Keeping in 2026
Signal protects private chats, WhatsApp wins on reach, and Messenger Kids gives parents control without ads or in-app purchases.
Quick Picks
Best overall: WhatsApp Messenger for broad reach and a 4.7 rating from 1.1 million Australian App Store ratings.
Best for privacy: Signal Private Messenger for free encrypted messaging and calls.
Best for kids: Messenger Kids for parent-managed contacts, usage limits, and no ads or in-app purchases.
Best for businesses: WhatsApp Business for automated replies and customer conversations.
Messaging apps now split into three camps: huge networks that make contact easy, privacy-first services that reduce data exposure, and specialist tools built around family or business use. The right pick depends less on stickers and more on who is already reachable, how much metadata you are comfortable sharing, and whether the app needs to handle work rather than weekend plans.
Everyday messaging with the widest reach
Network size still decides the practical winner. An app with excellent privacy controls is less useful if your family, clients, or community group refuses to install it. WhatsApp dominates the Australian App Store chart data supplied here, while Snapchat takes a more camera-led approach and LINE adds a large sticker and services ecosystem.
WhatsApp Messenger is the easiest recommendation for a mixed-contact list because the official Australian App Store listing shows a 4.7 rating from 1.1 million ratings and a No. 1 position in the Social Networking chart. It handles the basics cleanly: messaging, calls, and international communication over a data connection. The downside is not price—the app is free to download—but platform dependence and the broader data ecosystem around its parent company. Best for households and community groups that need one app almost everyone already has.
WhatsApp Messenger
Ideal for those looking for a secure and straightforward messaging solution to keep in touch with friends and family globally.
Snapchat is a different proposition from WhatsApp: it opens straight to the camera, then builds messaging around photos, video, Lenses, Filters, Bitmoji, and Stories. Video chat supports up to 16 friends, and new community-created Lenses arrive daily. That makes it more engaging for visual, informal conversations, but less efficient for searchable family logistics or long-running group plans. Best for adults and older teens who communicate through short visual updates rather than text-heavy chats.
Snapchat
Young adults and teenagers who enjoy interactive social sharing and engaging with multimedia content.
LINE earns its place through expressive communication rather than a minimalist chat window. The listing covers voice and video calls, mobile and desktop access, Wear OS support, and a large sticker catalogue. Compared with Snapchat, LINE is better suited to ongoing text conversations; compared with WhatsApp, its extra services and sticker culture can feel busier. Best for users whose friends or relatives already use LINE, especially across markets where it has stronger adoption.
LINE Calls & Messages
Casual users looking for a free messaging app with fun customisation options.
WhatsApp is the practical default, but it is not the most private option in this guide. Snapchat and LINE make conversation more expressive, yet both ask you to accept a more social, feature-heavy experience. The next group is for readers who would rather trade some convenience for stronger privacy controls or less centralised account data.
Privacy-first chats and calls
Signal and Session make different privacy promises. Signal focuses on free end-to-end encrypted communication in a familiar app format. Session removes the phone-number and email requirement from account creation and uses a decentralised server network. That distinction matters: Signal is easier to persuade a whole group to adopt, while Session reduces the amount of identity information tied to an account.
Signal gives privacy-conscious users the least disruptive switch from mainstream messaging. Its listing promises encrypted text, voice messages, photos, videos, GIFs, files, voice calls, and video calls, with group calls for up to 50 people. It is free and uses a phone data connection instead of SMS or MMS charges. Compared with Session, Signal has the more familiar feature set; compared with WhatsApp, the privacy positioning is much clearer. Best for people who want private everyday conversations without giving up group chats and media sharing.
Signal Private Messenger
Ideal for users prioritising privacy and security in their communications. It is well-suited for those who frequently share sensitive information.
Session goes further than Signal at account creation: the listing says no phone number or email is needed, and messages use a network of user-operated servers with private routing protocols. That is a meaningful advantage for people who do not want a chat account tied directly to their mobile identity. The compromise is adoption and familiarity; a privacy design is only useful if your contacts join, and the supplied listing gives fewer mainstream call and group details than Signal. Best for privacy-focused users who can accept a smaller network and a less conventional account model.
Session
Best suited for users prioritising privacy and security in their messaging apps. Ideal for those looking to avoid traditional tracking and data collection.
imo focuses on international communication, claiming more than 200 million users across over 170 countries and support for more than 30 languages. The Google Play description emphasises free high-quality voice and video calls, which gives it a practical role for families spread across borders. Its privacy language is less detailed in the supplied material than Signal or Session, so I would not choose it solely for confidential conversations. Best for multilingual families and international contacts who already use imo and care most about accessible calls.
imo
Individuals and families who need a cost-effective way to communicate internationally without worrying about call charges.
The Australian App Store listing for imo shows a 4.5 rating from 4.2K ratings, a 16+ age rating, and free download with in-app purchases. That gives it stronger visible local feedback than the Android listing, but the smaller review base makes the score less persuasive than WhatsApp's 1.1 million ratings. Its international calling focus is the reason to install it; the in-app purchase model is the reason to check the payment screen before committing to regular use. Best for adults making frequent cross-border calls who already have contacts on the service.
imo
Casual users who want to make free international calls and send messages without the hassle of subscriptions or fees.
Privacy is not one switch. Signal offers a familiar encrypted messenger, Session minimises account identifiers, and imo prioritises international reach. One surprising practical point is that the strongest privacy app here may not be the most useful one: a secure empty contact list still leaves you opening another app for everyday conversations.
Messaging for work and younger family members
Specialist apps solve problems that general-purpose messengers handle poorly. WhatsApp Business adds automation for customer conversations, while Messenger Kids gives parents control over contacts and usage. They should not be judged by the same standard: one is a lightweight customer-service tool, the other is a supervised communication space.
WhatsApp Business keeps the familiar WhatsApp foundation but adds business tools such as automated quick replies, free calls, and free international messaging according to the supplied listing. That can save a small operator from answering the same opening questions manually, although the app is still not a replacement for a full help-desk system or a team inbox. Compared with standard WhatsApp, it is more useful for customer-facing conversations; compared with enterprise software, it remains lightweight. Best for sole traders and small shops handling customer messages from one or a few phones.
WhatsApp Business
Small business owners and freelancers who need efficient customer communication without additional costs.
Messenger Kids puts control in the parent dashboard: adults can manage the contact list, receive notifications when a child blocks someone, and set bedtime usage limits. The listing also states there are no ads and no in-app purchases, which removes two common sources of friction in family apps. The limitation is obvious but important: it is not a general messenger for adult groups, and the parent setup is part of the experience. Best for families who want supervised calls and messages without advertising or purchase prompts.
Messenger Kids
This app is ideal for parents wanting to introduce their children to messaging in a controlled environment, ensuring safety and engagement.
These specialist picks are more focused than Signal or WhatsApp, and that is their advantage. A small business gets automation instead of another social feed; a parent gets contact approval and bedtime controls instead of hoping a general chat app behaves responsibly. For everyone else, the mainstream apps remain simpler because the people you need are already there.
Comparison table
| App | Best for | Key evidence from listing | Main limitation |
|---|---|---|---|
| WhatsApp Messenger | Everyday reach | 4.7 from 1.1M Australian App Store ratings; No. 1 Social Networking chart position | Privacy trade-offs and reliance on a large platform ecosystem |
| Signal | Private everyday chats | Encrypted messages and calls; group calls up to 50 | Everyone in the group must adopt it |
| Messenger Kids | Parent-supervised messaging | Parent contact controls, usage limits, no ads or in-app purchases | Not intended for general adult messaging |
| WhatsApp Business | Small-business conversations | Automated quick replies, free calls, international messaging | Too lightweight for a full support operation |
| Snapchat | Visual, informal chats | Camera-first design, Lenses, Filters, Stories, video chat up to 16 | Less practical for searchable, long-running conversations |
| Session | Minimal account identity | No phone number or email required; decentralised server network | Smaller network and less familiar setup |
| imo | International calls | Claims 200M+ users in 170+ countries; 4.5 from 4.2K Australian ratings | In-app purchases and less detailed privacy information here |
| LINE | Sticker-heavy messaging | Voice and video calls, desktop, mobile, Wear OS, extensive stickers | Useful mainly where contacts already use it |
Final recommendations
Pick WhatsApp Messenger if your priority is reaching the largest number of people with the least setup. Choose Signal if private chats matter and your contacts will install it. Session is the more privacy-radical pick for users who do not want a phone number or email attached to an account.
Parents should start with Messenger Kids because contact approval, bedtime limits, and the absence of ads or in-app purchases are more useful than a long sticker catalogue. Small operators should use WhatsApp Business for automated customer replies. For international families, imo makes sense only when its calling network matches the people you actually need to reach.
