Pretty interface, integrates with Apple Health, password protection - has the nicest features of other scale apps, plus this bonus: comes closest of any to really enabling use of a weight *range* for maintenance. I like to stay within a 5-pound variance from my goal. While this app allows a single goal weight number, the subtle red/green indicators show how far away I am, higher or lower.
Suggested enhancements: add Moving Average functionality; allow customizable settings for weight variation indicators (e.g. show red at 2 pounds over goal rather than 3, and 4 pounds under rather than 5); allow user to set no goal weight at all.
Great product - thank you, Arvid!
