New in Happy Scale 4.6

• Re-organized and simplified settings
• Much more control over the smoothing math
• Two new smoothing methods:
• “Happy Scale Smoothing”
• “Seven Day Moving Average”
• Visualizations in settings to help compare methods
• You can now export a CSV to any service, not just email
• Removed “Logout” button if there’s just one user profile
• “Tap To Release” is now an optional setting
• Many small bug fixes and improvements

Hi, Russ here.

Ever since I released this app, I've been slightly dissatisfied with the two smoothing algorithm choices. Each smoothing technique had its own weakness:

• Exponential Smoothing was poor for predicting today's weight.
• Double Exponential Smoothing was poor for predicting your rate of loss (weight trend).

For this update, I rolled up my sleeves and researched new statistical techniques for smoothing real-time data. But none of them had all the characteristics I was looking for.

Then I thought: What if I created a new smoothing algorithm that smoothed a weight based not only on past weights, but also future weights? If I created a new algorithm that was allowed to make slight adjustments to the last couple of days of smoothed values as new data were recorded, could I create a new technique that captures the best parts of Exponential Smoothing and Double Exponential Smoothing? So I tried to mesh them, and low and behold, there's now a new technique that is the best of everything! I call it “Happy Scale Smoothing.”

For existing users, this new technique is an optional opt-in. You can find it in the settings under the “How To Calculate” heading.

Give the new “Happy Scale Smoothing” a shot! I think it’s the best option for weight smoothing available anywhere. Grab the update here.
