Vibration Meter, seismograph vs iScan

Vibration meter is an app called seismograph or seismometer, which measures the strength of vibration, quakes, earthquakes, vibrations of the human body or any other objects around you. Our app allows for detecting and recording of seismic waves generated by earthquakes, volcanic eruptions, avalanches and other sources of vibration and shocks. Accelerometer in your mobile phone is used for detection of vibrations and measurement analysis. Graph presents a record of the ground motion at a measuring point. Ground movement or an object is presented as a function of time in the three Cartesian axes, with the z axis perpendicular to the Earth's surface and the x- and y- axes parallel to the surface. Mercalli intensity scale is a seismic scale used for measuring the intensity of an earthquake. It measures the effects of an earthquake and it is distinct from the moment of magnitude. Richter Scale assigns a magnitude number to quantify the energy released by an earthquake. Peak Ground Acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake. In this app we use Instrumental Intensity Scale (developed by The United States Geological Survey) which maps peak ground acceleration and peak ground velocity on an intensity scale similar to the felt Mercalli Scale. These values are used to create shake maps by seismologists on around the world. Mercalli Intensity Scale distinguishes the following levels of vibration and impact damage: I. Instrumental - Not felt. Recorded by seismographs. II. Weak - Felt only on top floors of high buildings. III. Slight - Felt indoors, like a passing light truck. IV. Moderate - Windows, doors rattle. Like passing train. V. Rather Strong - Felt by all. Small objects upset. VI. Strong - Books off shelves. Trees shake. Damage. VII. Very Strong - Difficult to stand. Buildings damaged. VIII. Destructive - Significant damage. Trees broken. IX. Violent - General panic. Serious damage. Cracks. X. Intense - Most buildings destroyed. Rails bent. XI. Extreme - Rails bent greatly. Pipelines destroyed. XII. Catastrophic - Near total damage. This app allows you monitor and share the results of your measurements with other users. Measure and monitor all vibration and shocks using smartphone or tablet!

iScan-D is a document scanner for anything from receipts and contracts to posters — no fixed page size. Capture, de-skew, OCR, search, and export all happen on your device. There's no sign-in, and your images and recognized text are never sent to a server. ■ Two scan modes • Normal scan: capture receipts, business cards, postcards, and everyday documents one sheet at a time. • Long scan: move the camera slowly downward to stitch a very long receipt into a single tall image. ■ Import from your photo library Already have a photo? Select one or several and bring them in as pages — no need to reshoot. ■ Precise cropping and de-skewing • The document's four corners are detected automatically. Fine-tune them by hand, with a magnifier so your finger never hides the corner. • A perspective transform straightens the page so a photo taken at an angle looks like it was shot head-on. • Corner cropping and a final rectangular crop are separate steps. ■ Finishing touches • Rotate, rectangular crop, brightness, contrast, saturation, sharpness, grayscale. • One-tap "Enhance" removes shadows and uneven lighting, whitens the background, and makes text crisp. • Brightness, contrast, and saturation preview in real time and can each be reset individually. ■ OCR in 9 languages Japanese, English, Italian, Spanish, French, German, Korean, and Chinese (Simplified / Traditional). OCR runs on device using Apple's technology, and the language follows your app language automatically. Recognized text is fully editable, and pages that fail recognition can be typed in by hand. ■ Find it, share it • Full-text search across titles, notes, and OCR text, with a snippet of the matching text. • PDF export embeds an invisible text layer so you can search inside the exported PDF. • Export as PDF, JPEG, or PNG, with paper sizes (A4, A5, B5, Letter, custom) and image sizes (original, large, medium, small, custom). • Combine multiple pages into one PDF in order and share it. ■ Organize and manage • Give each document a title and a note; the title is generated from the capture date. • The original image is always kept, so you can redo corner adjustment, perspective, editing, and OCR even after saving. • Deleted documents go to Trash. They can be restored for 10 days, then are permanently deleted automatically. You can also delete permanently right away. ■ Privacy • Images, OCR results, and document information are never sent off device. • All key processing, including OCR, works on device and offline. • No account or sign-in. • No cloud sync or built-in backup. ■ Requirements Supports the latest iOS and the two previous major versions. Works on iPhone and iPad. Note: This app shows a banner ad (Google AdMob) at the bottom of the document list.
