Rung
Read full descriptionHide full description
Most kitchen timers were built for boiling eggs. Rung was built for the rest of it. Set steps before you start or add them on the go. Anchor each one to the start or end - reduce heat after 10 minutes, brush with egg yolk 5 before it's done. No ads. No subscriptions. No cluttered menus. Just a dial, your steps, and a timer that feels like it was made to be used in a kitchen. Live Activity on your lock screen keeps your current step visible without unlocking your phone. A real bell tone and vibration that cuts through even on silent. Designed with the same care as the tools already in your kitchen. Good food takes time. Rung keeps track.
EXCORDER

EXCORDER β Extended Sensing for iPhone Born as an homage to the retro-futuristic spacecraft computer interfaces of science fiction, EXCORDER turns your iPhone into a real-time sensing device. Its distinctive interface combines a dark background, color-coded geometric panels, information rails, and instrument-style displays. Camera, LiDAR, GPS, compass, barometer, accelerometer, gyroscope, microphone β explore light, distance, location, direction, pressure, magnetic fields, vibration, sound, and more through one unified interface. * REAR IMAGING - View the rear camera feed with real-time overlays for approximate LiDAR center distance, vertical angle, and azimuth. RGB data around the ranging target is visualized as a simulated 32-band spectrum from 400β700 nm. β» The simulated spectrum represents RGB-derived color characteristics, not physical wavelength measurements from a spectrometer. β» LiDAR readings are approximate and may be affected by reflective or transparent surfaces, thin objects, and environmental conditions. Do not use them for precision or safety-critical measurements. * NAVIGATION - View your location on Apple Maps with latitude, longitude, GPS altitude, and heading. The built-in barometer provides atmospheric pressure and relative altitude from the start of measurement. Explore the magnetic field detected by iPhone with three-axis measurements and total field strength. Using the iPhone's relative 3D position from ARKit and the field strength measured at each point, EXCORDER estimates and displays the spatial direction in which the magnetic field is likely to become stronger as you move the device during a scan. Three-axis acceleration is sampled at 100 Hz, with FFT analysis providing a 0β50 Hz vibration spectrum, peak frequency, and peak amplitude. Local temperature and relative humidity are also retrieved for environmental context. β» The scan arrow does not indicate a magnet's north or south pole or the direction of magnetic field lines, nor does it determine the location or distance of a magnetic source. Estimates may become unstable depending on the surrounding environment, device movement, and ARKit tracking conditions. * ACOUSTIC - Analyze microphone input with relative digital level (dBFS) and a 32-band frequency spectrum from 40 Hzβ16 kHz. A 1.0Γβ6.0Γ digital microphone boost can be applied to both acoustic analysis and speech transcription. β» dBFS is a relative digital level, not a calibrated sound pressure level (dB SPL). * VOICE DECODE - Live transcription supports Japanese, English, Spanish, Korean, German, and French. On iOS 26 and later, EXCORDER supports on-device speech recognition. Using Apple Translation, recognized speech can be translated in real time into a selected target language: Japanese, English, Spanish, Korean, German, or French. * PRIVACY - Camera video, depth, simulated spectrum, audio, acoustic spectrum, pressure, magnetic field, acceleration, and vibration analysis data are not automatically stored permanently. When you use SNAPSHOT or RECORD, the currently displayed screen is saved to your photo library as an image or video. Transcription and translation content is discarded when the app closes. Your coordinates are sent to MET Norway to retrieve weather information. Except for this weather request and Appleβs speech recognition services when required, sensor data is not transmitted off the device. EXCORDER does not send images or videos saved by the user to the developer's servers. Bring the world beyond your natural senses closer through your iPhone.

Verdict
The clearest difference is price: EXCORDER at Free against Rung's $1.99. On update cadence, ads, in-app purchases and device support there is nothing between them.
