100% Free Sandbox Purchases: In-app purchases, subscriptions, and pro features in TestFlight are simulated in Apple's sandbox environment at $0.00 — your Apple Account is never billed.

How do I join the Khmer App TestFlight beta on iOS?
First, download Apple's official TestFlight app from the App Store on your iPhone. Then return to this page and tap the "Join Beta" button above. Your device will automatically open TestFlight and prompt you to accept the developer's beta invitation. Tap "Accept" and then "Install" to start testing Khmer App. If it says "This beta is full", tap "Get Slot Alerts" to be notified instantly when a slot opens.
Is testing Khmer App on TestFlight safe and free?
Yes, testing Khmer App is 100% safe and free. Every public TestFlight build must strictly follow Apple's App Review Guidelines and passes Apple's automated and manual security checks before public invitation links can be distributed. All betas operate within Apple's secure operating system sandbox and cannot access your device data without explicit permission. The beta is developed and maintained by ALIEN DEV CO.,LTD.
Do in-app purchases or subscriptions cost real money during TestFlight beta testing?
No. In TestFlight, Apple connects all transactions to its free Sandbox environment. Any in-app purchase, pro feature tier, or subscription inside Khmer App will display "[Environment: Sandbox]" and costs $0.00. Your Apple Account or credit card will never be billed for purchases made within a TestFlight beta build.
Does Khmer App work on iOS 27 and the latest iPhone models?
Yes, Khmer App is fully compatible with iOS 27 and iOS 26 across modern iPhones, including iPhone 18, 17, 16, 15, and 14 series. It supports modern iOS 27 capabilities including Siri AI, Dynamic Island, Lock Screen widgets, StandBy mode, and Apple Intelligence where applicable.
What should I do if the Khmer App TestFlight beta says "This beta is full"?
Apple enforces a strict cap of 10,000 public testers per TestFlight app. Popular betas fill up quickly, but spots reopen regularly because Apple automatically purges inactive testers, and ALIEN DEV CO.,LTD frequently clears inactive seats before dropping new beta builds. Tap the "Get Slot Alerts" button on this page to receive instant Email and Telegram alerts from CodeWing the moment an open slot is detected. You can also discover trending alternatives in the Utilities category.
Will installing the beta replace my current App Store version of Khmer App, and will I lose my data?
Installing the TestFlight beta will replace the App Store version on your iPhone, but all your local app data, documents, logins, and configurations are safely preserved. If you ever want to switch back to the stable public release, you can simply redownload Khmer App directly from the App Store at any time without losing your data.
How long does a TestFlight beta build last before it expires?
Each TestFlight build has a maximum lifespan of 90 days from the day the developer uploaded it to Apple. You can see the countdown days directly beneath Khmer App's title in your TestFlight app. Developers regularly release new builds with improvements, which automatically resets the 90-day timer so your testing is uninterrupted.
How do I send feedback or report bugs for Khmer App?
You can send feedback directly to ALIEN DEV CO.,LTD by taking a screenshot while using Khmer App and tapping "Share Beta Feedback", or by opening TestFlight, tapping Khmer App, and selecting "Send Beta Feedback". You can include notes, screenshots, and system logs to help the developer fix issues before the official App Store launch.
