Twitter Blue plan is on halt right now but when it resumes you will have to pay $11 per month if you subscribe from iOS, according to a report from The Information.

The report noted that the subscription plan will cost $7 per month if you purchase from the web. But it will be costlier on iOS to offset Apple’s App Store fees. Notably, Apple charges 30% fees to the developers for the first year of subscription, but it drops to 15% from the second year.
