Open Nettest is an independent and transparent tool for measurement of the Internet connection in fixed, cellular and WiFi networks. It has a strong focus on quality and reliability of the internet connection. Open Nettest measures several parameters: download and upload speed, ping (latency), jitter and packet loss. There are already several speed test apps in the marketplace that can do this. What makes Open Nettest different is that it is based on an open, transparent methodology. The measurement servers are located outside of the operators’ networks in several Internet peering exchange point. There are no internet service providers who would sponsor the measurement ecosystem. The app follows industry standards and KPIs as defined by BEREC, ITU and others. You can find more information about the measurement methodology at https://nettest.com/en/methodology. Another strong differentiator is the privacy. We do not collect any unnecessary personal data from the users and do not link the data collected to create user profiles. Moreover, we properly anonymise any sensitive data, such as location information and the IP address, before we use the data for statistical analysis and reports. To learn more, please visit https://nettest.com/en/privacy-policy. Open Nettest supports a variety of devices and internet access technologies, including WiFi, Cellular 2G, 3G, 4G / LTE, 4G+ and 5G NR SA / NR NSA. We would love to hear from you.

About

Must Ring

Features
Read full description

Must Ring is for the handful of things that cannot be missed — medication, picking someone up, the one task that has to happen today. Not a to-do list. Not a habit tracker. Just the few alarms that have to land, and an honest record of whether they did. RINGS THROUGH SILENT AND FOCUS Built on Apple's AlarmKit, so it rings full-screen like the system alarm — Silent on, any Focus mode, after the app is closed, after a restart. Two buttons on the Lock Screen: Done, or Snooze. IF NOBODY ANSWERS, SOMEONE GETS TOLD Set a delay. If the alarm still isn't confirmed after it, Must Ring sends a message to the contact you chose — so a missed dose doesn't pass in silence. You decide what they see. EVERY RING LEAVES A TRACE Done, done after snooze, skipped, unconfirmed, never delivered — each one is written down with its time and where you answered it (Lock Screen, widget or in the app). You can always tell "I forgot" apart from "it never rang". TEN TEMPLATES, THREE FIELDS Medication, meeting, pickup, errand, birthday, anniversary and more. Pick one, set the time, set the repeat. Lead time from 5 minutes up to a week. IN CHINA: STATUTORY WORKDAYS A work alarm can follow the official holiday calendar — it rings on make-up workdays and stays quiet on public holidays. A WIDGET THAT ANSWERS THE QUESTION What's next, how long is left, how today is going — on the Home Screen, without opening anything. PRIVATE BY DEFAULT Everything stays on your iPhone. No account, no sign-in, no server, no profiling. FREE TO START Same-day alarms always work, and so does the basic record — free, no account. A one-time purchase unlocks unlimited alarms, the template pack, escalation to a contact and full export. No subscription. Must Ring does not provide medical advice and is not a medical device. Always follow your prescriber's instructions.
