Lean will keep motivated on your weight loss journey. How? Using a custom algorithm, the app smoothes your daily weight logs so you don't have to worry about a bad weigh-in. Your weight goes up and down each day for various reasons that *aren't* changes in fat. Perhaps you have more food in your system; perhaps your body is holding more water. Just log your weight each day (in seconds) and Lean will do the rest. No more anxiety when stepping on the scales! HOW LEAN WILL GET YOU TO YOUR GOAL: • Lean's custom algorithm will smooth your weight over time. Not only will it smooth out daily fluctuations, it will also help you pick up longer trends in your weight. You'll be able to see how your weight is *actually* changing on a week to week, month to month basis. • The interactive chart will allow you to monitor your progress in detail. Filter the chart by week, month, three months, year or 'all-time' to stay up to date on how you're getting to your goal. • Turn your phone into a logbook. Effortlessly view, edit and delete old logs, all within the app. No need to carry around a pen and paper! Make progress to your goal whether you're home or away. • Make the app your own! You'll be able to choose your units (lb or kg), and use either the light or dark theme. The chart is customisable too - you can choose whether or not to smooth, to show your actual logs, to use a tooltip or to display your goal! And there's so much more to come. You'll just have to wait and see! --- Join the ever growing Lean user base and we'll help you stay on track and look your best. Lean is a brand-new app that's getting smarter and more useful with each update.

It tracks my weight and progress and smooths out fluctuations without too many bells and whistles and irritating requests for subscriptions and in-app purchases. Simple and to the point.

A couple of changes this time around which should make using Lean an even nicer experience. (i) Multilog is getting smarter! No longer will you need to confirm that you are 'finished logging' if you are just logging today's weight. If you're logging a weight from a different date, however, the behaviour will be as it is was - allowing you to log multiple weights sequentially. (ii) As requested, Lean will remember the chart duration that you had selected when you last used the app. Instead of always starting at 'All Time', the chart will display the period you were previously looking at! Please let me know any further improvements I can make!
