NL
Read full descriptionHide full description
Everyone in the Netherlands must always be able to receive an NL-Alert and NL-Alert must be clear to everyone. The NL-Alert app helps with this. The app has been specially developed for people who are regularly near the border with Germany or Belgium and therefore do not always receive NL-Alerts. The NL-Alert app is also for people with a visual or hearing impairment, which means that it is not always clear who receives a NL-Alert. 1. People who are often close to the border Their mobile phone may sometimes be connected to a German or Belgian cell tower. Those transmission towers do not send out an NL-Alert. With the NL-Alert app you will still receive the NL-Alert via your mobile internet connection. To receive messages data roaming must be available and allowed. 2. People who are hearing impaired or deaf It can be difficult for them to notice that an NL Alert has been sent. The app offers special accessibility features to help them with this. 3. People who are visually impaired or blind An NL-Alert is sometimes unclear to them. The app offers special accessibility features that make NL-Alert clearer.

Conversion Kit turns your iPhone into a fast, reliable unit converter that works entirely offline. Every conversion runs on data bundled inside the app. No internet connection, no account, no ads, and nothing about your usage ever leaves your device. WHAT YOU CAN CONVERT 43 categories and 207 units, including: ⢠Everyday ā length, mass, area, volume, time, speed, temperature, digital storage ⢠Engineering ā pressure, energy, power, force, torque, density, flow rate, acceleration, frequency, angle ⢠Electrical ā current, voltage, resistance, capacitance, charge, magnetic field, conductivity ⢠Science ā amount of substance, molar concentration, molar mass, viscosity, radioactivity, radiation dose, pH, decibel ⢠Astronomy ā astronomical distance and mass ⢠Clinical reference ā glucose, total cholesterol, creatinine, urea, bilirubin, hemoglobin, drug dosage FEATURES ⢠Instant results as you type ⢠Search across unit names, symbols, and aliases ⢠Favorites for the pairs you use most ⢠History you can browse, reopen, or switch off entirely ⢠Light and dark themes ⢠English and Vietnamese ⢠Accessibility support for VoiceOver and larger text BUILT FOR ACCURACY Conversion Kit uses decimal arithmetic instead of floating point, so results stay exact where they should be. Categories that need care, such as clinical analytes and drug dosage, show a warning before you convert, because those conversions depend on context like molar mass. PRIVACY No data collection. No analytics. No advertising. No account. Your history and favorites stay in the app's private storage on your device and are removed when you delete the app. NOTE Clinical unit conversions are provided for reference and educational purposes only. Conversion Kit is not a medical device and does not provide medical advice, diagnosis, or treatment. Always confirm values against your own clinical references and professional judgement.

Verdict
The clearest difference is ads: Conversion Kit at none against NL's shown. Conversion Kit also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.6). On price and in-app purchases there is nothing between them.
