IAmOK is a quick way to let the people who matter to you know that you are OK, that you have arrived, or that you are on your way, without writing the same message again and again. Prepare your usual messages, choose the contact, decide whether to add your location, and send it using Messages or WhatsApp. IAmOK helps you have the right update ready in seconds, while still letting you review it before the final send. It is especially useful for small messages that matter: • “I’ve arrived” • “I’m OK” • “On my way” • “I’m on the bus” • “I’ll let you know when I leave” • “Sharing my location” It also works well for families: teenagers who find it hard to text their parents, people living alone who want to check in quickly, couples who repeat the same routines, or anyone who needs to communicate something brief without losing time. Main features: • Reusable quick messages Save frequent updates and select them when you need them. • Prepared contacts Link each message to the right person so you don’t have to search every time. • Optional location Add a map link only when it makes sense to share where you are. • Messages or WhatsApp Prepare the update in the messaging app you prefer. • Quick access widget Start sending the selected message from the widget, without having to navigate through the app. • No hidden automatic sending IAmOK prepares the message; you review and confirm it before sending. • No ads Your messages are yours.

With IAmOK Plus, you can save unlimited quick messages, send unlimited messages, and use Family Sharing when available for your subscription.
