Based on the popular Sinometer, The Halometer is a fun iPhone app designed to help you achieve your lifestyle goals. Simply set yourself a 'Halo Quota' (a 'Halo' refers to a positive behaviour) for the week and mark your Halo on the app (by pressing the Angel button) each time you achieve a Halo behaviour (eg going to the gym, eating some fruit etc). You decide the 'Halo Target' and you decide what a Halo is. You must try to achieve your Halo Target for the week to which you can set yourself a reward for achieving it. As each week passes (12am Monday), your behaviour is recorded on a Halo Calendar as either a shining Halo (achieved your target), a yin yang symbol (you did some of your Halo behaviours but didn't achieve your target) or a Red Devil (you didn't do any of your halo behaviours for the week). You have the option of creating multiple Halometers to manage multiple categories. Download the app now and reward your good side.
