What's New in Happy Scale

2026.5.3

June 2, 2026

PREDICTIONS MAKEOVER The Predictions card has been given a fresh new look! You can now name each prediction and tap it to open a beautiful full-screen view that shows exactly how it was calculated, with a share button to send it to friends and family. We've improved accessibility with full Dynamic Type, gone over VoiceOver with a fine-tooth comb, and added help links throughout to guide you through configuring the app so your predictions show the data you want to see. CHART SHORTCUTS You can now edit the row of date shortcuts below the Weight Chart. Add as many as you like, pick whatever time frames are meaningful to you, and arrange them however you want. Choose from "last X days," "since a particular day," or a custom date range. FIXES AND TWEAKS We're always doing our best to make lots of small improvements across the app. For more details on how to set up these new features, head to Settings → Help & Support → Recent Updates. P.S. We're proud to announce that our team has grown! For the first time ever, Happy Scale is now maintained by a team of three full-time people who all share a deep love of craftsmanship. We're so grateful for the financial support you've given us throughout the years, and we hope to keep making this app better for you for many years to come!

Only time I have reviewed an app in a positive way of my own free will

I love this app I think it’s amazing! I hope the creators could produce a calorie counting app that could combine with this app and somehow also pull my body metrics in too to have it all in one spot that’s not apple health. I love this app so much. I love that you can customize so much of it!! And as someone who is very organized I like that this app shows every detail and has animated confetti when you hit a milestone! I hope the creators keep expanding!

Love your app

Love this app, it’s helped me so much with the mental up and down of the weight swings. Have you ever considered a scatter graph to show weight trends over the month? I sometimes still struggle with “oh my weight is the same as it was at the start of the month” without seeing that weight in context to the weights around it

It changes weight units on its own

From time to time it switches from lb to kg on its own

Simple and effective

It’s easy to get caught up in the bells and whistles of some of these newer Health apps. Happy Scale is perfect for me because I’m focused on weight loss. I know what I’m eating. I know how I’m exercising. I just need a simple interface to track my weight. The fact that it gives me some fireworks to celebrate is icing on the cake…of which I’ll take just one bite, thank you. Happy Scale works. Period.

The best way to not obsess with the scale

I love this app because it allows me to track my progress in small chunks that I know I can accomplish. I also love the averages and being able to use my 10-day low. Super customizable and very robust. If you need a weight tracker app - look no further. Yes it integrates with Apple health so I get my readings directly from my scale!
