See where your weight is really heading.
Tidra is a weight tracker for iPhone and Android. It looks past the daily ups and downs and shows your trend, so you can see your progress and when you're likely to reach your goal.
One weigh-in doesn't tell the whole story.
Water, salt and exercise can move the scale a couple of pounds overnight. Tidra draws a trend line through your weigh-ins so you can see which way you're actually going. Drag across the chart to read each weigh-in.
Everything you need to track your weight.
Trend weight
A smoothed weight that reflects your real progress. Daily weigh-ins appear as dots around it.
Milestones
Split a big goal into smaller steps. Tidra marks each one as you reach it and shows how long it took.
Forecast Plus
See where your trend is heading over the next 1 to 12 months, with a likely date for each milestone.
Widgets
Check your trend or log a weigh-in from your home screen. One widget is free, and Plus includes the rest.
Health sync
Syncs with Apple Health and Health Connect, so weigh-ins from smart scales like Renpho and Eufy come in automatically.

Hi, I’m Richard, and I made Tidra. Like a lot of you, I’ve spent most of my life losing weight and gaining it back, so I know how frustrating it can be. When I recently started getting back in shape, I wanted an app that showed my progress without making a big deal of every bad morning on the scale. So I built one.
Your weight goes up and down from day to day, and a lot of that is natural fluctuations. Tidra helps you focus on where you’re heading over weeks, not fixate on what the scale said this morning. There are no ads and your data stays in your own iCloud or Google account.
It’s just me working on this, so if something bugs you or you have an idea, tell me. I read everything.
