"Block calls" works very similar to Decline button, you will NOT be notified about blocked calls, unless your carrier sends notifications about missed calls. Blocked caller still able to leave a voicemail, as it happens on carrier's side (contact your carrier for details). We have NO access to your call log, however please note – iOS doesn't put blocked calls into call log. "Identify caller" adds labels from your list to Phone app for incoming calls, call log and "Keypad" tab. ■ IMPORTANT: Private & Unknown calls ■ Nor this app, nor any other app in the App Store, doesn't allow you to block or identify Private, Hidden or Unknown calls due to the way iOS call blocking and identification system works. We have described some workarounds in FAQ & Help section of our app. ■ IMPORTANT: Ranges of numbers ■ iOS call blocking and identification system is limited to about 1.9 million numbers per app. This is (roughly) equal to 6 digits of number. Please note, only first 1.9 million numbers from your list (ordered ascending), including all numbers from the ranges in your list, will be used by iOS. This limit DOESN'T allow you to block the WHOLE specific carrier, area code or country code. ■ Contact Us, Support & Feedback ■ If you have any questions – feel free to contact us.

How many pixels in a 12 megapixels image? How does that compare to difference aspect ratio? What is the resolution of Digital Cinema with 21:9 aspect ratio? How many megapixels by giving X width and Y height by image? How about the aspect ratio? The answer is here! This is a megapixel-resolution calculator, a tool to calculate and convert the graphical resolution base on 4 different aspect ratios 4:3 (SD), 16:9 (HD/fHD/4K), 21:9 (cinema) and 1:1. This tool also calculates and convert graphical resolution to megapixels. The output will include 4 different aspect ratios 4:3 (SD), 16:9 (HD/fHD/4K), 21:9 (cinema) and 1:1 if the ratio match one of these. Preview box will give you an impression for resolution input. 21:9, 16:9 and 4:3 is the ratio of x:y or width:height of the image sensor or output image/video format. Older digital cameras/camcorders aspect ratio is usually 4:3 (SD). However newer digital cameras/camcorders aspect ratio is 16:9 (HD/fHD/4K). Video cameras such as camcorders can be either 4:3 (SD) or 16:9 (HD/fHD/4K). Some camcorders (video and digital) can do both 4:3 (SD) and 16:9 (HD/fHD/4K).
