Here are the five of those essential iPhone apps that I feel help transform iPhone users into iPhone power users. While I’m happy to pay for the premium service (and this gives me access to two-factor authentication using YubiKey), Bitwarden is one of those rare services. – especially for password managers – that offers a decent free service. I’ve tried countless password managers, and the free version of Bitwarden is better than the paid version of some of the competition. Not only is the iOS app great, but it offers a smooth, cross-platform service. And yet I keep using – and paying for – Freedome. This started out as my go-to VPN service on my iPhone, but quickly moved to being my go-to VPN on all my devices. It’s everything that I want from a VPN. It’s offered by a trusted name in security. The service is excellent. And the apps are reliable and easy to use. And it’s not just documents I scan with it. It’s great for scanning posters, protected slides, and pretty much anything else you might want to change into a PDF. There are lots of apps that promise to turn documents into PDFs, but this one is by far the best, easiest to use, and most reliable. And for those who use other Microsoft apps, this integrates well into the ecosystem. iVerify is a security app that combines in-depth information and step-by-step guides on how iPhone users can take to secure their device, along with threat detection scanners to make sure that no nasties have made their way onto the device. I consider myself quite proficient when it comes to iOS security, but I was amazed at how much I learned and how many tips I got from this app. And the great thing is that it’s updated quickly for new releases. Authy is great because it has advanced features such as the ability to sync information across multiple devices, back up to iCloud, and it even supports 8-digit tokens. A great app, and a great service.
