Impact metrics help you to\nprioritize, and issues are categorized to help you take action. Information at\nboth device model and device spec level enables you to find the most effective\nway to act. \n[Get started for native games](/games/sdk/performance-tuner/custom-engine) [Get started for Unity games](/games/sdk/performance-tuner/unity)\n\n*** ** * ** ***\n\nWhat are the benefits?\n\nAndroid Performance Tuner (APT) helps you deliver a high-quality experience to more\nusers.\n\nNew! Understand your loading times and their impact on abandonment\n\nAPT tracks both your loading time and loading\nabandonment across multiple types of loading (first loads, cold loads, warm\nloads and interlevel loads). It shows you the impact that longer loading times\nhas on abandonment for your game, so that you can determine the optimal loading\ntime.\n\nMeasure the quality of your user experience\n\nAPT shows you the frame rate and loading time\nperformance of your game on actual user devices in the real world, so you get\ndirect insight into their experience. All metrics are customized to your\ntargets, so you can understand how the game is performing relative to your\nspecific goals.\n\nDiagnose and prioritise your game performance issues\n\nFrame rate and loading time issues are broken out by your quality levels and\nyour in-game annotations, as well as device model, to help you narrow down the\nroot cause. For each frame rate issue, you can see GPU time as well as CPU time,\nso you can assess what type of optimization may be needed. The number of\naffected sessions is also shown, so you can understand what's affecting your\nusers most, and decide what devices or game scenes to focus on first.\n\nGet the best out of every device\n\nAs well as surfacing performance rate issues, APT\nhighlights opportunities for you to improve your user experience by increasing\nfidelity on devices which already perform well but that have room to go further.\nThis enables you to ensure that every user gets the best possible experience of\nyour game.\n\nHow does it work?\n\nAndroid Performance Tuner works with Android vitals.\n\n- Android Performance Tuner records and aggregates live frame time and loading information from your game or app, alongside game annotations and fidelity parameters that you provide.\n- When you publish a version of your game or app with Android Performance Tuner, this performance data is uploaded to Google Play and unlocks new performance insights in Android vitals.\n\nTo get these performance insights, you must integrate Android Performance Tuner into\nyour game or app and then publish it on Google Play:\n\nRequirements\n\nFor devices:\n\nAndroid Performance Tuner (APT) works on any Android device (with or without Google\nPlay services) running Android 4.1 (API level 16) or later. This is over 99% of\nall active Android devices.\n\nFor all developers:\n\n- Access to Android vitals\n- Product only available in the new Google Play Console\n\nAdditional requirements for Unity developers:\n\n- Unity version 2017.4 or later and [.NET version 4.6](https://dotnet.microsoft.com/download/dotnet-framework/net46)\n- To use APK Expansion files, Unity 2018.2 is required\n- For improved frame pacing and GPU measurements, Unity version 2019.3.14 or later is required\n- For Addressables scenes support, Unity 2019.3 or later and [Addressables package 1.19.4](https://docs.unity3d.com/Packages/com.unity.addressables@0.8/manual/index.html) or later are required.\n\nLearn about Android Performance Tuner\n\nWe have codelabs to walk you through integrating Android Performance Tuner into your\ngame for both C/C++ and Unity Engine integrations:\n\n- [Codelab: Integrating Android Performance Tuner into your C/C++ Android game](https://codelabs.developers.google.com/codelabs/android-performance-tuner-native/)\n- [Codelab: Integrating Android Performance Tuner into your Unity game](https://codelabs.developers.google.com/codelabs/android-performance-tuner-unity/)\n\nReferences for the C/C++ and Unity Engine SDKs:\n\n- [Android Performance Tuner C/C++ reference](/games/sdk/reference/performance-tuner/custom-engine)\n- [Android Performance Tuner Unity reference](/games/sdk/reference/performance-tuner/unity)\n\nAdditional resources"]]
