Ever accidentally opened your carβs trunk by squashing the keyfob in your pocket? Or returned to your car after what should have been a quick charging stop, only to find out itβs not fully charged? I have! The app can alert you if you forgot to lock your car or accidentally left a door or the trunk open. Notifications: - A door is open. - A door is unlocked. - Charging stopped. Features: - Set the minimum time a door or trunk needs to be open or unlocked before youβre alerted. - Configure a State of Charge (SoC) threshold, so that charging is only considered stopped below this limit. - Choose whether you want charging stopped notifications when DC fast charging, or for AC charging as well. Supported vehicles: The app should work with all connected Audi models. Please let us know if you experience any issues. Disclaimer: Car Notifier is not affiliated with, endorsed by, or officially connected to Audi AG in any way. It uses an unofficial and undocumented API, which may change at any time. If the API changes, the app might stop working, and depending on the change, we might not be able to make it work again.

EXPOCAL is the on-set exposure companion for cinematographers, DPs, and gaffers β every calculation you reach for between scouting a location and rolling, in one fast, dark-themed app. Nail exposure Incident metering math built on ISO 2720: dial in ISO/EI, shutter angle, and frame rate to get the exact T-stop β or work backwards from an aperture to the lux you need. Handles dual-base sensors and broadcast gain (dB) too. Match your gear Pick from a built-in library of 47 cinema cameras and 241 lenses. Check sensor coverage, mount compatibility, and how a lens, extender, or adapter behaves across your kit. Director's viewfinder Frame a shot right on your phone. Choose a camera and focal length and the live preview matches that lens's field of view β pinch or use the thumb zoom slider to find the frame before the camera is even built. Overlay mode draws the exact framing on a wide preview. Depth & focus Hyperfocal distance, depth of field, and aperture sweeps with sweet-spot, diffraction, and noise guidance. Light & color ND filter stops, white-balance mired shifts, and CTB/CTO/plus-green gel recommendations. Timecode Read SMPTE LTC straight from the audio input and show it full-screen, big enough to hold in front of a lens. When the sound has a clock and the camera does not, you film the number. The reader flywheels through dropouts and says when it has lost lock rather than pretending it hasn't. Export Generate clean PDF reports for scene and sensor planning. EXPOCAL gives estimates to support your judgment on set β always confirm critical exposures with your meter and monitor.
