## What is FKey Browser?

Looking for a way to send F-Keys through a web browser on IOS?

This Web Browser is built with function key keyboard support for some 5250 IBM Main Frame web emulators and other websites that require function key input.

Our standard keyboard configuration is free for all users to use on any website.

PREMIUM WEBSITE CUSTOM KEYBOARD CONFIGURATIONS
Some websites are built a little different from standard.  To work with these sites, we have worked with users to develop custom configurations to properly send F-Keys to these non-standard websites.  To use these Custom Keyboard Configurations, you will need to watch a rewarded ad for temporary access or subscribe for unlimited access without ads.

A custom keyboard configuration has been built and tested with CN Rail CATS website (we are not affiliated with CN).

For more information on Custom Keyboard Configurations, please see https://fkeybrowser.freshdesk.com/a/solutions/articles/72000521227

SUBSCRIPTION INFO
FKey Keyboards now allows you to purchase a subscription to have unlimited access to Custom keyboard Configurations and remove all App ads.

Subscriptions with a free trial period will automatically renew to a paid subscription.  You can cancel your subscription in the iTunes settings at least 24-hours before the end of the free trial period. Subscription payments will be charged to your iTunes Account at confirmation of your purchase and upon commencement of each renewal term.

You can cancel a free trial or subscription anytime by cancelling your subscription through your iTunes account settings.

### 2/5 — Works with CATS

*2025-05-29, version 1.1.0*

It does work well with the CATS program. The subscription payment is much too pricey for an app that is likely quite stable now. The ad revenue for free access isn’t a bad, but it’s not like it’s candy crush. A 30 second advertisement EVERY 24 hour period so I can check work is AGGRESSIVE. I’d rather pay $30 or $40 up front and be done with it. Update - the now 60 second ad freezes the app up and I’ve switch to the competing app that has a ONE-TIME payment instead of this greedy subscription based service.

### 5/5 — Great app for fkeys

*2024-10-24, version 1.1.0*

Great app, helps a lot having fkeys on the phone. 
Will be cool if i can actually link fkeys in to my iPhones actual keyboard somehow and use it in safari or other browsers, 🤪
Even for a monthly fee..

### 5/5 — Great app!

*2024-01-15*

App works flawlessly for my application.   I view a short commercial or play a random game for a few seconds. Not an issue what’s so ever.  Great app! Highly recommend.

### 3/5 — Works with CATS

*2023-11-24, version 1.1.0*

### 5/5 — Longer use Review

*2023-11-03, version 1.1.0*

This app does everything you need to do with Pressing F5, F3, F11… my trial ran out, I haven’t paid but the 5 second ads once a day are a small price to pay to keep this free. If you have a new iPhone and can’t get your old Fkeys app, this is the one to get!

### 1/5 — Con job

*2023-08-17*

To further use the app, you are either forced to pay a monthly subscription or watch advertisements for limited access. Don’t download. Junk!!

**Developer response:** Thank you for sharing your feedback. I genuinely apologize for any inconvenience you might have experienced. The app is designed to be accessible with a free version that includes ads. This helps support ongoing development and maintenance. Alternatively, the subscription model offers an ad-free experience for users who prefer it. As an independent developer, this balance helps ensure that I can continue to offer a free version while also maintaining the app's quality and functionality. Your feedback is valued, and I'm always working to improve the app experience for all users. I appreciate your understanding and consideration.

### 4/5 — Works with CATS

*2023-04-26, version 1.0.6*

you have to watch a 30sec ad to use the keys on cats but they actually do work and it’s free.

### 1/5 — Junk

*2022-12-01, version 1.0.4*

App doesn’t even work…

### 1/5 — Needing a bug fix

*2022-11-15, version 1.0.4*

Railroader here, F Keys are essential to our lives. I have been using the developer beta of this app for a couple of years, it worked flawlessly with CATS. Now that I have installed the full version of the app, the F Keys appear, but do not function if clicked. 

Otherwise, when this app is functioning properly as the beta did, it’s 5 stars.

### 1/5 — No cats

*2022-10-18, version 1.0.4*

Does not work with cats
