Three ways to measure when you don't have a measuring tape or a ruler: 1 – AGAINST YOUR SCREEN Simple and precise for small measurements. 2 – IN AUGMENTED REALITY Place a virtual measuring tape on a vertical or horizontal surface, such as a wall, table or floor. Built with ARKit. 3 – USING AIRPRINT Print a ruler! Accuracy depends on the printer, so check the result against the on-screen ruler.

QuietCall, also searched as GoyoCall and 고요콜, is an iPhone call blocker with number notes, saved caller names and SMS filters. Numbers to block. Numbers to remember. One simple place. QuietCall brings country-aware call blocking and a personal number notebook together. Enter a number on the home screen and choose to create a rule or write a note. BLOCK NUMBERS ACROSS COUNTRIES Work with phone number formats from 245 countries and regions. Choose a country to work with its local and international number formats. Explore optional number ranges for South Korea, the US, Japan, Taiwan, Canada, the UK, France, Brazil, Chile, Slovakia and Spain. Group recurring prefixes and select the ranges you want to apply. REMEMBER WHO IS CALLING Save a name and private note for a clinic, repair service or class organizer without adding them to Contacts. Enable caller identification to recognize saved names when calls arrive. Keep personal notes separate in the app. Favorites, search and the side index make numbers easy to find. Import a number from the share menu. Korean initial-letter search is also supported. A CLEAR, EASY FLOW Start with a number, then choose what to do. Open your rules and notes directly from home. Apply large lists with visible progress, and keep allowed numbers ahead of QuietCall's blocking rules. Organize eligible messages with number and word filters too. YOUR OWN ICLOUD BACKUP Back up and restore blocking rules and number notes separately in your iCloud Drive. Start without signing up. Your numbers and notes are stored on your device. EXPAND WHEN YOU NEED TO Blocking and 100 number notes are free. A one-time purchase removes ads; another option removes ads and unlocks the free 100-note limit. Local prices appear before purchase, and purchases can be restored. No subscription. Enable call blocking, message filtering and caller identification in iPhone Settings. Available in Korean, English, Japanese, German, Spanish, French and Simplified Chinese. See the privacy policy for advertising data details.

Verdict
The clearest difference is in-app purchases: Ruler / Measuring Tape at none against QuietCall's 4. Ruler / Measuring Tape also leads on ads (none vs shown). QuietCall's advantage is update cadence (every 2 days vs every 4 months). On price, device support and iOS requirement there is nothing between them.
