About

Nexio

Features
Read full description

Nexio is a great new app that is very useful for anyone that values privacy. Adults and kids as well as businesspeople benefit from this app. Nexio has three main functions: 1) Advanced Audio Recording and Transcription, 2) Hide Contacts & Photos, and 3) Customizable Dummy Views (no one than you will notice the app or get in) The first function, which we call Dictaflowing, captures audio in real-time and transcribes it in over 60 languages and regional accents, with optional iCloud backup for safekeeping. In everyday life you can use it for dictating memory notes or keeping a diary. As a diary it is great for kids that have not yet learned to write or for you that effortlessly and fast want to get your thoughts in writing. For authorities and business, the app is very useful for recording and transcribing during meetings, or if you want to make client notes or remember things for later. Great for any client-based business or authorities within the legal or health care sectors. When you have started to record you can even use the app while the screen lock is on. All transcribed material can be edited afterwards and be easily shared -if you want to. You can even transcribe old audio files with speeches that you have stored on your phone. Free users can now record up to 3 free dictations, each lasting 20 seconds, and can add up to 3 hidden contacts for free. The second function allows you to keep certain contacts and pictures hidden. Those contacts and pictures that you save in the app, or import to the app, will not be shown anywhere else on the phone. You can choose if you want to upload this information to iCloud or not. The third function allows you to hide the app itself by camouflage. You do that by choosing an app icon from our many alternatives. You can even choose a dummy page that opens if someone unauthorized still finds the app and tries to get in. The dummy page then asks for 6-digit pin code for updating reasons but only the one who knows the correct pin code gets into the real app. In other words, you can feel completely safe that your information is secure. In addition to the functions above you can feel completely safe that your information is for your eyes only. We are committed to keeping your data secure and private. Your contacts, photos, and all sensitive data remain securely on your device and are never uploaded to any server or shared with third parties. You have full control over your information, and all data is managed locally within the app. The app itself is also fully customizable — choose your own app icon and set personalized colors and buttons and background. Nexio supports the following in-app languages and many more when it comes to dictating: English Arabic Chinese Danish Norwegian Finnish Turkish Portuguese Bengali French German Hindi Japanese Korean Spanish Swedish Ukrainian Russian Vietnamese Pricing Annual Subscription: $2.99/year Lifetime Access: $24.99 (one-time payment for lifetime access) Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period.
