Enter more fully into the prayer of the Armenian Church. Tarkman helps you follow services at participating Armenian churches as they happen, understand the words and actions, and participate with confidence. Whether you are visiting for the first time or deepening a lifelong faith, it offers a guide to the worship unfolding around you. Live service following is available only at participating Armenian churches that use Tarkman to share their services. Language and unfamiliar rituals can make a service difficult to follow. Tarkman brings together the current reading, translations, and explanations to help you discover the meaning of the prayers. FOLLOW THE SERVICE LIVE Join a public service at a participating Armenian church from the app, a service link, or a QR code. Follow along as the service progresses. READ AND UNDERSTAND Choose from the languages available for each reading, including English, Classical Armenian, and transliteration. Compare texts side by side and explore explanations of what is happening and why it matters. STAY CONNECTED TO THE PRAYER Change reading languages and open part details while keeping your place in the service. Participating churches can share the Divine Liturgy and other Armenian Church services, including morning and evening worship. No account is needed to follow a public service. Please silence your device during worship and use Tarkman thoughtfully as a companion to prayer.
