Happy Helper

After lapsing use for over a year - then coming back to find all my information was still there —fabulous! A record of my weight journey since 2012. It is definitely a happy helper! 😊

Just brilliant!

I have been using the (paid / no adverts) app for years as a daily weigher and it has supported me so well - I am a luddite, very uncurious too, so pretty backwards with most tech, but I recently discovered under settings that after my year long 60lb loss on Mounjaro / Tirzepatide I can put my goal weight AND track my maintenance within so many pounds up or down of that set point!! I love this feature so so much never mind all the cool history I get to keep, the beautiful lists and graphs and analyses of my weight trends - I just really, really love my daily check ins and today I know I am half a pound above my maintenance range (delighted that is all after a blow out eve with family yesterday) and I will haul my eating in and up my walking just a little bit the next couple of days. This app’s attractively sleek and ultra intelligent “thought of absolutely everything” design is a big tool in keeping me on point with my health goals. As a lifelong dieter who has bounced around all these kind of apps I honestly believe there is no other weight tracking app that can touch this. Did I say I love it?!

Response from developer

Thank you so much! I’m delighted Weight Diary and the goal range feature have been so helpful.

LOVE THIS APP!

Really easy to use and is very accurate.

Weight Diary

This product began as a way to monitor my weight on a weight loss journey. Then, unexpectedly, I have CAD AND 4 blocked arteries, with 3 stents. Now EVERY pound matters and my docs can “see” it. Thank you! Highly recommend.
