Falcon Pro is by far my favourite Twitter app. The developer is actively adding new features, fixing bugs and take requests for new features. Whenever I have had a problem, a quick tweet to them and they have either told me what the fix is or told me they will fix in the next update.
Suddenly, Falcon Pro has reached its Twitter imposed 100, 000 user token limit and all within 3 months of leaving BETA. This is the limit of users Twitter will allow the app to connect to their account. One hundred thousand users sounds like a lot, but not when it's clearly explained.
A token is taken up by the app out of its stock of 100, 000, when a user uses the app to connect to their Twitter account (this is when you input your email and password). If that user then decides to no longer use the app (for what ever reason), then that token is still taken. It doesn't automatically get revoked when/if the user deletes the app from their device. This means their could be hundreds (if not thousands) of tokens taken up by users who no longer use the app and have deleted the app from their device. The only way to free up a token for the app is to log on to your account on the Twitter website, go to the 'Apps' section of your settings and revoke access for that app.
Sadly, not many people know about this, so if won't release these tokens for new users to come along and use the app.
What does this mean for Falcon Pro's current users? Nothing. Unless you want to use it on a new device. It also means that the developer will no longer get any new customers, as new users cannot use the app. This could also potentially cause problems for the stores that sell the apps. If a new user were to download the app having paid the £0.64/€0.73/$0.99, then finds the app is no longer accepting new tokens. If they don't return to the Play store within 15 minutes of the purchase, they would be out-of-pocket. In the Apple App Store, users would have to go through Apple for a refund explaining why.
In this case, the developer, Joaquim Vergès, was quick to add a disclaimer on the front of the Play Store description to state that the app would no longer accept new users for the time being.
In an effort to resolve this, Vergès has taken to Twitter to ask his users to sign a petition he will send to Twitter to get the block removed or extended. At the time of writing, over 2000 people had signed it. Personally, I signed it straight away and retweeted the petition to keep this fantastic app on the market and continuously improved.
