你可以依據偏好儲存及分類內容。
Ultimate Guitar (UG) 匯集了超過 110 萬首歌曲的和弦和分頁，是全球成長速度最快的吉他社群之一。其中有超過 1 千萬名註冊使用者定期參與論壇，並貢獻分頁、課程和文章。此外，UG 也提供所有音樂產業的最新消息、評論和網誌，介紹音樂製作過程中的幕後推手。
具體措施
Ultimate Guitar 擁有眾多活躍的 Android 使用者，因此他們不斷尋求觸及新客群。UG 非常期待 Google Play 免安裝體驗和「立即試用」功能，因為他們相信，增加試用次數能夠推動更多使用者成長。
針對 UG 建構「Google Play 免安裝」技術可讓開發人員享有簡單流暢的體驗。藉助 React Native 的額外程式庫，UG 的應用程式大小超過 4 MB 的限制。不過，使用者已發現並註冊 Google Play 免安裝 10 MB 計畫，因此可以發布免安裝應用程式。歡迎立即試用，你也可以為大小不到 10 MB 的免安裝應用程式立即啟用。他們在短短兩週內就自行規劃及設計免安裝應用程式，包括花費一週的時間開發及測試自家免安裝應用程式，再透過測試群組推出。
成果
UG 導入「立即體驗」後，發現試用應用程式的使用者迅速增加。其中約 20% 的使用者點選「立即試用」按鈕後，便會安裝自家應用程式。如此一來，在開發一週才經過一週，安裝次數就大幅提升了 8%。在取得出色成果後，UG 也持續投注心力發展免安裝應用程式、改善使用者資料追蹤效率、打造更良好的使用者新手上路體驗，以及專注於營利。
Ultimate Guitar 執行長 Michail Trutnev 表示：
「在 Google 的協助下，我們能夠利用免安裝應用程式功能拓展應用程式的目標對象。這個做法可讓使用者輕鬆提供優質內容，而不需要付出大量心力。」

It has over 10 million registered users who regularly participate in forums and contribute tabs, lessons, and articles. UG also provides all of the latest music industry news, reviews, and blogs about the inside scoop in music making.\n\nWhat they did\n-------------\n\nUltimate Guitar has a big fan base of engaged Android users, and they are always looking to reach new people. UG is excited about Google Play Instant and the Try Now feature, as they are confident that increased trials will result in more user growth.\n\nBuilding for Google Play Instant was a straightforward and smooth experience for UG. With React Native's additional library, UG's app was above the 4MB limit requirement. However, having discovered and signed up to [Google Play Instant's 10MB program](https://docs.google.com/forms/d/e/1FAIpQLScVKwTCzjeh6brMyCKpJqdcxZXW7WX9ho__TCj5YVEz-Kaovw/viewform), they were able to publish an instant app. TRY NOW and web banners can also be instantly enabled for any instant app under 10MB. In less than two weeks in total, they planned and designed their instant app, including a week spent developing and testing it, before rolling it out on the release track.\n\nResults\n-------\n\nWith the implementation of TRY NOW, UG saw an immediate increase in people trying their app. \\~20% of those who tried the app through the TRY NOW button went on to install their app. This led to a remarkable increase in installs of 8%, after just a week of development time. Following these strong results, UG continued to invest in its instant app, improving user data tracking, building better user onboarding, and focusing on monetization.\n\nMichail Trutnev, CEO at Ultimate Guitar, commented:\n\n*\"Google gives us a great opportunity to increase the app's audience with the instant app feature. This is a simple way to provide users with high-quality content without asking them to put in a lot of effort.\"*\n\nGet started\n-----------\n\nAll app and game developers can build instant apps.
