Many reviewers have shared good ideas to improve it, but it seems the developer hasn’t heard or acted on those. ### 3/5 — Fair *2015-01-16* If it included a blood glucose tracker it would be sufficient for my needs. It needs to be able to edit old entries and add old entries. I was disappointed the nutrition section had no trackers. ## Frequently asked questions about H2O Overload ### What is H2O Overload used for?
