Beware, the access will be granted to all devices on the same wireless network - it would not be sensible to activate this service on any network that is not of your best trust. A simple toggle widget is included. Requires Root: Yes. Status: Original source code repo vanished

aka Alarm wakes you at the right moment within a 30-minute window you choose, instead of jolting you out of bed at a fixed time. How it works: while an alarm is armed the app uses the microphone to measure the ambient sound level of your room. It maintains a rolling 5-minute baseline of "how quiet it really is" and watches for the level to rise above that baseline by a configurable threshold. When that happens — you turn over, sigh, shift the duvet — the alarm fires. If nothing happens, the alarm fires at the end of the window so you never oversleep. Privacy: the microphone is active only while an alarm is set, and audio is processed in memory then immediately discarded. No audio buffer is ever written to disk, persisted, or transmitted off your device. There is no network code in this app at all — no analytics, no crash reporting, no third-party SDKs. Features: • Wake-up window with smart spike detection on the microphone • 60-second gradual volume fade-in for the alarm tone • Motion-driven snooze (lightly move the phone) with random duration clamped to the remaining window • Slide up anywhere to dismiss • Foreground service keeps the alarm reliable overnight • Material 3 UI with dark + light mode aka Alarm is open source under the MIT licence: https://github.com/seeingred/aka-alarm

This is a baresip based SIP and mobile calling and messaging User Agent for Android. Currently baresip+ supports SIP and mobile based voice calls and messages as well as SIP based video calls. In addition, voice conference calls, voicemail Message Waiting Indication as well as blind and attended call transfers are available when SIP is used. MMS messaging is not supported yet. In SIP calls audio can be coded with Opus, AMR, Codec2, G.729, G.722, G.722.1, or PCMU/PCMA codecs. Video can be coded with VP9, VP8, H.265, H.264, or AV1 codecs. Security is achieved via TLS or WSS SIP signaling transport and ZRTP or (DTLS) SRTP media encapsulation. Development of baresip+ is motivated by need for a secure, open source SIP based VoIP User Agent for Android that does not depend on proprietary, third party push notification services. Contacts, mobile calling, and SMS messaging were added in order to reduce app pollution. This application can be installed on Android devices running Android version 9 or later. Mobile calling and messaging needs Android version 10 or later. If you don't need video calling, you can instead of this app install its lighter weight sister app baresip. Source code is available at GitHub, where also issues can be reported.
