UK ETA App vs Online: Which Application Method Is Better?

UK ETA App vs Online: Which Application Method Should You Choose?

When you apply for a UK Electronic Travel Authorisation, you have two options: the UK ETA smartphone app (available for both iOS and Android) or the GOV.UK website. Both methods lead to the same result, an approved ETA linked to your passport, but the experience of applying through each can be quite different.

In this detailed comparison, we walk you through both methods step by step, highlight the advantages and disadvantages of each, and help you decide which option is best for your situation.

Overview: Two Ways to Apply

The UK government launched the ETA app alongside the web application to give travellers flexibility. Here is a quick summary:

• UK ETA App: A dedicated mobile application that guides you through the process, uses your phone’s NFC chip to scan your passport, and takes your photo with the phone camera.
• GOV.UK Website: A browser-based application form that works on any device. You manually enter passport details and upload a photo from your files.

Both methods cost £16 and have the same processing time (most applications are approved within minutes, with a maximum of 3 working days). The ETA itself is identical regardless of how you apply.

The UK ETA App: Step-by-Step

Here is what the application process looks like using the mobile app:

Step 1: Download the App

Search for “UK ETA” in the Apple App Store or Google Play Store. The official app is published by the UK Home Office. Be careful to download the correct app, as there are third-party apps that charge higher fees and are not official. The official app is free to download.

Step 2: Create an Account or Sign In

You will need to create an account with your email address or sign in if you have used the app before. This account allows you to track your application and apply for ETAs for multiple people.

Step 3: Scan Your Passport Using NFC

This is the key feature of the app. You hold your biometric passport against your phone, and the NFC reader extracts your personal details, passport number, expiry date, and nationality automatically. This eliminates manual data entry and reduces the chance of errors.

To use this feature, your phone must have an NFC chip (most modern smartphones do) and your passport must be biometric (look for the chip symbol on the cover).

Step 4: Take Your Photo

The app guides you through taking a passport-style photo using your phone camera. It provides real-time feedback on positioning, lighting, and background, which can be helpful if you are unsure whether your photo meets the requirements.

Step 5: Answer Security Questions

You will answer questions about criminal convictions, previous immigration issues, and your travel plans. These are the same questions asked on the website.

Step 6: Pay and Submit

Pay the £16 fee using a debit or credit card and submit your application.

The GOV.UK Website: Step-by-Step

Here is what the process looks like using the online form:

Step 1: Navigate to the Application Page

Go to the official UK ETA application page on GOV.UK. You can access this from any device with a web browser, including desktop computers, laptops, tablets, and phones.

Step 2: Enter Your Passport Details Manually

You will type in your passport number, full name, date of birth, nationality, and passport expiry date. Double-check every field, as errors are the most common cause of application problems.

Step 3: Upload a Photo

You upload a digital photo from your device. The photo must meet the standard UK passport photo requirements. Unlike the app, there is no guided photo feature, so you need to ensure the photo is correct before uploading.

For photo guidance, read our UK ETA Photo Requirements Guide.

Step 4: Answer Security Questions

The same set of questions as the app regarding criminal history, immigration issues, and travel purpose.

Step 5: Pay and Submit

Pay the £16 fee and submit. You will receive a confirmation email with your reference number.

App Advantages

• NFC passport scanning: Eliminates manual data entry and reduces errors. This is especially useful for passports with long names or complex characters.
• Guided photo feature: The real-time camera guidance helps you take a compliant photo on the first attempt.
• Convenience: You can apply from anywhere using just your phone and passport. No need for a computer or pre-prepared photo file.
• Multiple applications: The app stores your account, making it easy to apply for family members one after another.
• Application tracking: You can check the status of your application directly in the app.

App Disadvantages

• NFC scanning failures: Some travellers report that the NFC scan fails repeatedly, particularly with certain phone models or passport types. If the scan does not work, you cannot proceed with the app and must switch to the website.
• Photo rejection: Despite the guided photo feature, the app is reportedly strict about photo quality. Multiple travellers report having their photo rejected several times before it is accepted.
• App crashes: Some users, particularly on older devices, report the app crashing during the application process. This can be frustrating if you lose progress.
• Storage and updates: The app requires storage space on your phone and may need to be updated before use, which can be inconvenient if you are in a location with limited internet.
• Device compatibility: Not all phones support NFC passport scanning. Older phones or budget models may lack this feature.

Website Advantages

• Stability: The website is generally more stable than the app, with fewer reports of crashes or technical issues.
• Larger screen: If using a desktop computer or laptop, you have a bigger screen to review your details, which reduces the chance of overlooking errors.
• No installation required: You do not need to download anything. Just open a browser and go.
• Works on any device: Any device with a web browser can access the website, including older computers and tablets.
• Pre-prepared photos: You can take your time preparing the perfect photo in advance and upload the file, rather than trying to take one on the spot.

Website Disadvantages

• Manual data entry: You must type all passport details by hand, which increases the risk of typos or errors.
• No guided photo: You are on your own when it comes to ensuring your photo meets requirements. If the photo is rejected, you must prepare and upload a new one.
• No NFC scanning: You cannot scan your passport, so you need to have your passport in front of you and carefully copy the details.

Side-by-Side Comparison

Common App Issues Reported by Travellers

Travel forums are full of reports from people who struggled with the app. The most common complaints include:

• NFC not detecting passport: This is the most frequent issue. Solutions include removing your phone case, placing the passport flat on a hard surface, and slowly moving the phone across the back cover of the passport until the chip is detected.
• Photo rejected repeatedly: The app’s photo validation is reportedly stricter than the website’s. Travellers suggest using natural light, a plain white background, and ensuring no shadows fall across your face.
• App freezing during payment: Some users report the app freezing at the payment stage. If this happens, close the app and reopen it. Your progress should be saved, but check that the payment was not processed before retrying.
• Error messages without explanation: The app sometimes displays generic error messages that do not explain what went wrong. In these cases, switching to the website is often the quickest solution.

Our Recommendation: Which Should You Use?

Based on the available evidence and traveller feedback, here is our recommendation:

Try the app first. If your phone supports NFC and the app works smoothly, the passport scanning feature alone makes it worth using. The guided photo is also a genuine advantage, especially for families applying for children who may struggle with photo requirements.

Switch to the website if the app gives you trouble. Do not waste hours fighting with NFC scanning errors or photo rejections. The website is reliable and straightforward. You lose the convenience of NFC scanning, but you gain stability.

Use the website from the start if you prefer working on a larger screen, your phone does not have NFC, or you want to prepare everything (including the photo) in advance before starting the application.

Supported Devices and Requirements

UK ETA App Requirements

Frequently Asked Questions

Does it matter which method I use? Will one be approved faster?

No. Both methods feed into the same processing system. Your application will be reviewed in exactly the same way and at the same speed regardless of how you submit it.

Can I start on the app and finish on the website?

No. Each application method is separate. If you start on the app and encounter problems, you will need to begin a new application on the website. However, since you will not have paid yet (payment is the final step), there is no financial loss.

Is the app free to download?

Yes. The official UK ETA app is free. Be wary of third-party apps that charge a download fee or a higher application fee. The only cost should be the £16 government fee.

Can I apply for my family using one phone?

Yes. Using the app, you can complete applications for multiple family members using the same phone. You will need each person’s passport for the NFC scan and each person’s photo.

What if neither method works for me?

If you cannot complete the application through either the app or the website, contact UKVI (UK Visas and Immigration) for assistance. They can help troubleshoot technical issues. You can reach them via webchat on the GOV.UK website.

Key Takeaways
