Hey everyone! I recently released an Android app I've been putting significant effort into.
Auto Sound Recorder AI is a voice-activated audio recorder that automatically starts recording when it detects your voice, and stops when silence returns. Perfect for meetings, lectures, or any scenario where you need hands-free recording.
Key features:
- 🎙️ Voice-activated auto-record — starts when you speak
- 🔇 Automatic silence skip — no more hours of dead air
- 📅 Scheduled recording — set it and forget it
- 🔒 100% local processing — your voice data never leaves your phone
- 📅 3-day free trial
Would love honest feedback — what would make this actually useful for your workflow?

Welcome to the foreground-service-on-Android-camera-and-audio-stack club — it's a small clubhouse and we're glad to have you. A couple of practical notes from someone running the equivalent on the video side:
The VAD trigger is the magic, but OEM background restriction is going to be your single biggest support-ticket source, especially Xiaomi MIUI and Samsung's "deep sleep." Even with a foreground-service notification, MIUI will silently kill voice-triggered services after ~30 minutes of "no user-visible work" if the user hasn't explicitly added you to the autostart whitelist. Worth proactively detecting and showing an OEM-specific onboarding card.
For the "100% local processing" claim — that's exactly the right positioning, but Play Store's Data Safety form actively penalizes honesty here. The form has no first-class way to say "we genuinely process zero data off-device," so reviewers sometimes flag the gap. Pre-emptively documenting your AndroidManifest permissions in your listing description helps.
One question: how are you handling the case where VAD is triggered by something the user didn't intend to record (e.g., music, TV in the background)? That's the failure mode that always burned me on similar always-listening designs — curious if you found a clean UX for after-the-fact pruning.
Built something philosophically adjacent on the video side (screen-off camera/recorder) and the privacy positioning is the same fight. Happy to compare notes.
Hello there! Thank you very much for your excellent suggestions! You are absolutely right—backend restrictions need to be configured to prevent certain Android models from being terminated. This is spot on! I will incorporate it into the next version. Your suggestion regarding data review is also very good, but the official version of my app has already passed the review process. Finally, regarding the issue with VAD audio detection, the logic I’ve designed has been tested extensively on actual devices and will not be falsely triggered to start recording by sounds other than human speech. However, I have found that if human speech is accompanied by background music, it will not trigger the recording; the background noise needs to be at a relatively low volume. Therefore, if it is singing, it will not start recording even though it contains human voices. I have also previously researched audio solutions such as noise reduction to address this issue. As I have always worked in the field of audio and video-related hardware and electronics, I am very keen to develop practical applications in this area to share with everyone. Finally, my sincere thanks to you! Please feel free to get in touch at any time! If you have a Telegram or Discord ID, please send it to me and I will add you! Thank you!
I’ve also had a look at your website and noticed you’re designing an app that allows users to take photos and record videos directly from the lock screen! That’s a brilliant idea! It enables mobile phones to make full and convenient use of their built-in functions to integrate with other platforms, such as live streaming. In fact, as mobile phones are products with limited external hardware capabilities, designing physical interfaces with practical functions is rather restrictive; audio and video are undoubtedly the only viable avenues for designing software that enables external integration! That’s my personal view.
