Developers can now offer up free trials for non-subscription apps on the iOS App store following an update to the Store Review Guidelines.

While developers initially had the ability to offer free trials for apps prior, it was limited to apps that came with a subscription.

The new guidelines set out that Non-subscription apps may offer a free time-based trial period before presenting a full unlock option. This can be done by setting up a Non-Consumable IAP item at Price Tier 0 that follows the naming convention: '14-day Trial'.

The guidelines also state that apps must identify its duration time before the start of the trial along with what content or services will no longer be accessible when the trial ends.

Developers must also make any downstream charges the user would need to pay for full functionality clear.

Running out of steam

Apple also moved to clarify its position over multi-platform following last month’s decision to put the brakes on its plans to launch Steam Link on the iOS.

Steam Link was designed to let users play Steam games on their mobile devices, with content streamed from a nearby host system such as a PC or Mac.

"Apps that operate across multiple platforms may allow users to access content, subscriptions, or features they have acquired elsewhere, provided those items are also available as in-app purchases within the app," the guidelines state.

"You must not directly or indirectly target iOS users to use a purchasing method other than in-app purchase, and your general communications about other purchasing methods must not discourage use of in-app purchase."
