INDIVIDUALIZE YOUR CARD Create a stunning card easily: select a picture and choose your favorite background color, gradient color, and text color.

MORE FEATURES Match your Home Screen by choosing from three different app icons Fine-tune display settings based on your needs Got a lot of cards? Find the card you’re looking for easily with search Support for English, German, Spanish, French, Italian and Portuguese ABOUT DEJAVIEW We think, paper business cards have reached the end of their lives. In most cases you always print way too much and when your job title or phone number changes, you still have left plenty of them. So, what about NFC cards made of plastic or metal? While this solution may be more versatile and easier to update, you still have a physical card, adding bulk to your wallet. And: you are depending on a service, hosted by the provider of your NFC card. Which means no offline functionality and once the company stops offering their service, your plastic/metal card is simply useless. For this reason, DejaView works without any external dependencies or servers involved. When you choose to create a vCard QR code, your contact information is included in the QR code itself – eliminating the need for an internet connection when scanning the code.

Verdict
The clearest difference is rating: DejaView at 4.7 against iDisplay's 1.9. iDisplay's advantage is in-app purchases (none vs 4) and review sentiment (20% vs 0%). On price and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. DejaView sells 4 one-off in-app purchases. iDisplay asks for nothing beyond the download.
DejaView holds the better App Store score, 4.7 against 1.9. That said, the two scores are not equally well evidenced: iDisplay has 105 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 20% of iDisplay's written reviews are positive against 0% of DejaView's, so the app with the better star average is not the one people write more warmly about.
iDisplay ships an update every 6 weeks, DejaView every 4 months. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
