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. If you like the app, please do not forget to rate it in the app store and please also consider to write a review.

Welcome to Mobolize for iOS! Try out our newest features and help provide feedback on the cutting edge technology coming out of the Mobolize labs. All-in one Mobile Data Protection app built on our SmartVPN® technology that looks like a VPN but has the smarts that other VPN solutions lack, to deliver you the fastest, most secure and efficient mobile data experience possible. Three awesome features to protect and enhance mobile data on your device: PROTECT • Blocks malware and phishing sites in the browser/apps/email/texts to always keep you safe and secure. ENCRYPT • Protects your data privacy when using Wi-Fi by automatically encrypting unsecured content and ensuring your Wi-Fi connection is safe. • Works without breaking most VPN sensitive apps like streaming video services. BOND • Provides the best possible data connection by leveraging both the Wi-Fi and cellular data networks to keep your apps and services running continuously. • By intelligently augmenting poor performing Wi-Fi with cellular data, Wi-Fi dead zones are eliminated. Congested Wi-Fi is unclogged with load-balancing of Wi-Fi and cellular which provides seamless transitions when moving from Wi-Fi to cellular coverage for most apps and services. HOW IT WORKS • SmartVPN® technology automatically and intelligently applies threat protection, encryption and wifi+cell bonding only when necessary to ensure the fastest possible performance and most efficient battery usage of any VPN. • The "VPN" will be visible on the Status Bar while any of features are running. You will also see occasional notifications when status changes in the app and as you connect and disconnect from Wi-Fi. • Automatically encrypts your data when you connect to Wi-Fi networks. Avoids re-encrypting of HTTPS for faster performance, less battery usage and compatibility with all apps and video services. IMPORTANT NOTES • The Wi-Fi logo may disappear when the VPN is running, even though you are still connected to Wi-Fi. This is a known occurrence for all VPNs. To check you are still on Wi-Fi tap on your iPhone settings app and look at the Wi-Fi status. • Please note that if you check the data or battery usage on your phone, it may appear as though this app is using a lot of data and battery. However, this app isn’t actually using all that data/battery. Reporting for the data/battery usage has been shifted from your other apps to this one, because your data now passes through this app so it can manage your security and connectivity. Actual battery usage will be minimal – on average 0.1%. • Reporting an issue with the application is performed by tapping the Menu (upper right corner of the app) and then tapping ‘Report problem.’ When reporting a problem, please be as specific as you can.
