Those download numbers you see in Play Store app listings are a terrible way to judge whether an app is worth installing. I’ve seen it with popular VPNs, antivirus apps, caller ID services, and even password managers.
Of course, I’m not saying that all popular apps are bad. Nothing of the sort. But there are many apps that I would recommend most people avoid, either for privacy and security concerns or because they try to solve problems that Android already handles perfectly well on its own.
What popular app would you not recommend in 2026?

VPN Turbo

Turbo VPN has over 500 million downloads on the Play Store, making it seem like a safe bet. It’s also free and does exactly what you’d expect from a VPN. But the thing is, free vpn It almost always has a trap. And no, I’m not just talking about the ads in Turbo VPN’s free tier, although they are pretty annoying on their own.
Turbo VPN doesn’t have the cleanest track record. Over the years, there have been several reports about its questionable data practices and ties to entities based in China. Honestly, Turbo VPN is just one example. I would say the same applies to most free VPNs that offer unlimited data. This is because running a VPN service isn’t cheap, so if you don’t pay for it, the company is making profits elsewhere.
It’s a little ironic when you think about it. The point of using a VPN is to improve your privacy, but when you opt for an app like Turbo VPN, you could end up compromising it. If you really want a VPN that doesn’t cost anything, opt for providers that have been around for a few years and have a solid track record, like Proton VPN.
last pass

A password manager is one of those apps that lives or dies by trust. And for a long time, LastPass was a prominent name among users and security experts. But after everything that’s happened in the last few years, I don’t think the confidence is there anymore.
LastPass’ biggest problem is its security record. Is 2022 default It was particularly serious. In that incident, attackers managed to steal customer data and even gained access to LastPass’ security architecture. Now, to be fair, no password manager is completely immune to these types of attacks. But what makes LastPass so difficult to recommend is that the 2022 breach was not an isolated event.
true caller

Truecaller promises to solve a problem that almost everyone faces. It helps identify unknown people, blocks spam, and can save you from having to answer another telemarketing call in the middle of lunch. And the reason why it works so well is that it has created a massive database using the information contributed by its users. It has over a billion downloads (yes, that’s a “B”) on the Play Store alone and is also available on iOS.
The problem is that when you sign up for Truecaller, you’re not just sharing your own information; you’re also sharing data about everyone in your contact list. That means someone who has never heard of Truecaller could still have your name and phone number in their database.
My biggest problem with Truecaller is the large number of app permissions it requests. In addition to contacts, it requests access to call logs, messages, location, files, photos, videos and audio. Sure, some of these are optional, but it’s not comforting when an app like Truecaller asks for so many permissions to begin with. Most importantly, while Truecaller filled a real gap a few years ago, Android now handles unwanted calls and messages much more effectively.
Cleaner

CCleaner is a popular storage cleaning app that claims to remove junk files and unnecessary data. It can also detect applications that consume too many resources. The only problem is that modern Android phones simply no longer need a separate app to do most of this.
On Android you can now see which apps are draining your battery or use excessive mobile data through the settings menu. There’s also Google’s built-in Files app, which includes a dedicated cleanup tab to remove junk files, duplicate photos, old screenshots, and unused apps. And unlike CCleaner, it’s completely free.
So yes, CCleaner is not necessarily a bad app, but it solves a problem that doesn’t need a solution. I’m also not a fan of how aggressively the app pushes its subscription to get you to try out some of its useful features.
AVG AntiVirus and Security

Pankil Shah / Android Authority
Antivirus apps like AVG AntiVirus & Security are easy to find in the Play Store. In addition to malware protection, these apps often offer additional features such as privacy tools, app blocking, Wi-Fi security controls, and even performance optimization tools. But even then, they are largely unnecessary on Android.
Android already comes with many useful security features. Also, most of the important ones are enabled by default. For example, Google Play Protect continually scans all the apps on your phone, including those you’ve downloaded, for harmful behavior. And if it detects something suspicious, it can alert you and even automatically delete the app. There are also features like Android Safe Browsing that scan for malicious links in real time to protect you from viruses and phishing scams.
In some ways, AVG and most other Android antivirus apps simply duplicate features that already exist and, worse yet, charge you for them. The reality is, as long as you stick to the Play Store for apps and don’t do anything silly, like disable Android’s built-in security features, you generally won’t have to worry about your phone getting infected.
