Your Church Center events now fill your church app's calendar on their own

The short version. Planning Center is an extension of GoodBarber, the no-code app builder, that fills a Calendar section with the events a church publishes on Church Center over the next six months. Recurring events appear once per date, at their public times, in the church's time zone, with their image, location and description. When an event has a sign-up, a button opens the form in the app. You connect it by signing in with a Planning Center Calendar administrator account: there is no key to copy. It is free for Content apps: each section counts as one of the extensions included in your plan.Many churches already run their calendar in Planning Center: it counts 78,000 active churches and 4 million active users, according to its About page, consulted in October 2026.

Find answers in podcasts with GoodBarber Chatbot

Take a local radio station with live programmes, a schedule and interviews available on demand in its app. Every recording has a title and a description. Those help listeners browse, but an interview often contains useful details that never make it into the summary.In our example, the episode is called “The city we share”. Its description introduces a conversation about everyday life in the city. During the recording, an urban planner explains the city's approach to summer heat: planting trees along school routes, adding shade to playgrounds and replacing some paved surfaces with planted areas.None of those measures appears in the title or description. A listener remembers the subject and asks:Which episode explained how the city plans to reduce summer heat?We have added audio podcasts as knowledge sources for GoodBarber Chatbot so questions like this can lead back to your programmes. There are two levels: the written information you publish about each episode, and the spoken content you choose to have transcribed.

Turn documents into answers with GoodBarber Chatbot

In any app, publishing a useful document is only part of the job. People also need to find the right information when they are about to act. A clearly named file helps someone browsing a library, but a reader may arrive with a more immediate question.Employee communication is only one possible application. The same approach can support learning resources, member guides, technical references or any other useful documents shared through an app. For our example, consider a colleague trying to book a client trip who needs to know:Which travel expenses need prior approval?We have added document sources to GoodBarber Chatbot so that the files you already maintain can support these conversations. You select the documents. Users ask in their own words. The assistant looks for relevant passages and uses them to build a response.The question becomes a way into the policy. Employees can start with the decision in front of them, even when they do not know the title of the document that explains it.

Siri Actions: ask your GoodBarber iOS app for its latest article or video

Siri Actions now answers two new questions: the latest article and the latest video in a section of a GoodBarber iOS app. Siri names the item and offers to open it by voice. They reach every app with its next store update. Siri Actions is the set of questions a GoodBarber iOS app answers out loud, for newspapers, radio stations, schools, organizations and any app that publishes content. Its first question, "What's new", gives an overview of your home screen. When we launched it in September 2026, we said the next one would be the latest article in a section. Here it is, and the latest video comes with it. Each goes straight to one item and offers to open it. Your audience goes from a question to the article in a single conversation, without searching for it.

The AI Extension Builder now runs on GPT-6 Luna

OpenAI released GPT-6 Sol and GPT-6 Luna on September 22, 2026, after GPT-6 Astra, the flagship of the family, earlier the same month. Luna is the smallest of the three.

Can a mobile app work without an internet connection? What works offline and what doesn’t

A mobile app can work partially or completely without a connection if the data and functions required for a task are available on the device. A guide can display a page that was opened earlier. A podcast app can play an episode downloaded in advance. An offline-first field tool may even store a completed action locally and synchronize it later.Those are three different technical promises:Cached content: an item previously loaded from the network remains temporarily available on the device.Deliberately saved content: the user chooses an article, audio file or another supported item to keep for later.Offline-first operation: the app performs all or a critical subset of its core functions from local data. If it also accepts changes offline, those changes must be synchronized and any conflicts handled when connectivity returns.Our Offline extension supports the first two approaches for compatible content: keeping previously loaded material available and letting readers save supported items through Favorites.Android’s definition of an offline-first app requires all or a critical subset of its core functions to work without the internet. That architecture requires local data sources. If the app also accepts changes offline, it needs synchronization rules and a way to handle conflicts when connectivity returns. It is much broader than caching a page.This distinction matters when selecting an app builder or describing your own app. “Available offline” should identify a specific task. It should not imply that every screen and action behaves as it does online.

AI assistants get your business wrong? Fix the content they cite

Imagine a listener asking an assistant about a programme in September 2026 and receiving its 2025 schedule. The cited page was accurate when it was published. Nothing on it says the information has expired, so the assistant treats it as current. The listener misses the programme, or writes to your team to ask which version is right. An old membership offer or a former studio address produces the same confusion.Carolyn Shelby raised this issue in Search Engine Journal on September 7, 2026: contradictory information about a brand can mislead AI search. Three mechanisms explain why your own pages end up in the answer:Assistants retrieve pages by wording. A question that uses a programme's former name leads straight to an archive that still contains it.They merge several sources into one answer. The dates that separated those sources become hard to see.A new page does not retire the old one. The current schedule and the old statement both remain available, and nothing tells the assistant which one applies.So start with the source the assistant cited. Which sentence on that page no longer describes your service? That sentence needs a date and a route to the current answer.
