Balanced has been the most impactful productivity tool for me for a long time. The ability to remind myself about recurring tasks without a specific deadline is just wonderful and complements my other (specific) task management extremely well. I use it especially to stay on touch with people, something I am naturally forgetful about. I simply add in that I want to catch up and contact a specific person 4 times a year and then the app will make sure to remind me in the right time Windows.
Why only 4 stars so far? I deeply miss the ability to sync and backup the data between devices. The tool has become so important to me that I cant afford to set up my iPhone as new anymore as I would lose all my balanced data.
Again, kudos for such a wonderful and useful app. Once it gets export/import/sync ability I give it 6 stars :)
