Twab is a new geolocation app for iphones. It promises to improve your daily life and to help you in case of an emergency. It connects to your phone contacts and shows you which of these contacts are in close proximity to your location. You chose the contacts with which you want to share your location. You chose the duration that you wish your location trail to remain active. In case of an emergency, you simply press the “Panic Button” and twab automatically sends an SOS alert, notifying your situation and location simultaneously to all your contacts that have registered you on the “emergency list” All the options in twab are tailor-made to suit your individual needs in order to help you feel better and safer! Twab is a tool that helps in everyday life. A tailor-made geo-location tool to suit the needs of every individual user. All the options in the settings menu are customized so that the user of twab has the ultimate control while using the app. So: Through the contacts menu, the user can select whether to share/not share his/her current location with a contact. To which contacts he/she wishes to be visible or not. The user also selects the contacts for which he/she wishes to be notified once they press the “Panic Button” Finally the user can adjust the duration that he/she wishes for his location trail to remain active. These three parameters render twab a valuable geolocation tool that is here to help us and simplify our everyday life in a nice way. Reflect on the times that you have felt isolated and lonely simply because you were unaware of the presence of friends and loved ones that were in close proximity to you. With twab we can have a pretty clear picture of friends/family that are near our location, so that we can meet up or ask for their help in case of an emergency. Of course only if they want to be traced by us. Nobody can see your location if you don’t allow them to. If you change your mind about a specific contact and you no longer want to share your location with them, you can simply de-activate the sharing of the location through the contacts menu. This person will NOT be notified about your action. The philosophy of twab has nothing to do with spying on people but has every individual user as its epicenter, and that’s why there is a 20km limit in the scan radius. Twab does not spy on people, it locates contacts that want to be visible to you so you can meet up! Nice and easy! Panic Button Twab has another highly important function. The "Panic Button" is active on the main screen of the premium version! Through the contacts menu, twabers are asked to specify which of their phonebook contacts they want to notify in case of an emergency, by activating them as "panic contacts". When a twaber presses the Panic Button the following options appear: Medical Emergency Fire Breaking & entering/robbery Attempted rape/persecution Once the user selects one of these options, all contacts who have him / her active in the "panic button" alerts will simultaneously receive an SOS (morse code) notification with the exact location and the reason for the distress signal. Free Version users can list Premium Version users as “Panic Button contacts”. Free Version users can only be notified in case of an emergency of others but not use the Panic Button for themselves. The purpose of the "Panic Button" function is to provide us with a sense of security when we are alone and/or feel threatened. When we need help, silently, without having to speak, we can immediately inform people that we trust about our location and situation so that they can help us.
