The International Cystitis Network has developed an app for iPhones and iPads that gives patients with overactive bladders the confidence to select foods and drinks that should not aggravate their condition. It contains a list of more than 250 items divided into three categories: bladder friendly foods, foods worth trying cautiously, and foods to avoid. Users will also find highlighted foods and beverages that will be soothing to them during interstitial cystitis flare-ups. There are even recommendations for lower acid wines, pale ale beers and mixed drink mixers. The app can be purchased for 99 cents and downloaded from Apple’s App store.
