# Digital Growth Charts App - START HERE **Category:** [Digital Growth Charts App](https://forum.rcpch.tech/c/digital-growth-charts-app/40) **Created:** 2025-10-13 12:21 UTC **Views:** 93 **Replies:** 9 **URL:** https://forum.rcpch.tech/t/digital-growth-charts-app-start-here/608 --- ## Post #1 by @michael.barton RCPCH is developing a digital growth charts app. It's designed for use by parents, carers and healthcare professionals. Built on top of our world leading [Growth Charts API](https://growth.rcpch.ac.uk/), RCPCH is committed to keeping the app maintained and available. It's optimised for use on mobile phones but also works on tablets. The app is not finished but you can test it now. It's safe and accurate to use and but we're still adding new features which may not be free (see the roadmap below). We've created a special area in our forum and we are actively looking for your feedback! You can [register here](https://forum.rcpch.tech/signup) then introduce yourself [here](https://forum.rcpch.tech/c/rcpch-digital-growth-charts/digital-growth-charts-app/40), let us know what you're using the app for and what we could improve. ## Installing the test version > [!tip] App stores coming soon! > Whilst we prepare the app for the iOS App Store and Google Play Store, you can install the app from your mobile browser. > > You will need to reinstall the app from the app stores once available. ### If you have an iPhone or iPad Visit the app in Safari at [https://rcpch.github.io/digital-growth-charts-app/](https://rcpch.github.io/digital-growth-charts-app/). You can then install it by adding it to your home screen: 1. Open the Share menu, available at the bottom or top of the browser. 2. Click **Add to Home Screen**. 3. Confirm the name of the app; the name is user-editable. 4. Click **Add**. On iOS and iPadOS, bookmarks to websites and PWAs look the same on the home screen. See [PWA Installation | web.dev](https://web.dev/learn/pwa/installation#ios_and_ipados_installation) for further instructions. ### If you have an Android phone or tablet Visit the app in your browser at [https://rcpch.github.io/digital-growth-charts-app/](https://rcpch.github.io/digital-growth-charts-app/). You can then install it by clicking the "Add to home screen" button in your browser. See [PWA Installation | web.dev](https://web.dev/learn/pwa/installation#android_installation) for further instructions. ## How much will it cost The app is free and will always be free for plotting individual measurements. We are working on a pricing model to support saving measurements over time and to store multiple children - details to be released soon. ## Roadmap The app currently supports: - Plotting multiple measurements in a single session Coming in the first half of 2026: - Saving measurements for multiple children - Sharing measurements with other parents/carers/professionals These features will require registering but plotting individual measurements will always be free and not require registration. ## Use by health professionals This app is recommended for individual measurements or parents tracking the growth of a few children over time. If you already have an electronic patient record in your place of work, it's better to integrate our Digital Growth Charts directly. We have a [demo and contact details here](https://www.rcpch.ac.uk/resources/growth-charts/digital/about#explore-the-demo-and-contact-us). ## Frequently asked questions ### How do I find the centile or SDS value for a measurement? Click on the dot in the chart to see the centile: ![Screenshot 2025-10-29 110038|287x500, 75%](upload://cRBKh1NyuUvEx8qJ3UFEnkVIFO8.png) The SDS value and full details are in the table under the "details" column (you may need to scroll to the right on the table): ![Screenshot 2025-10-29 110114|285x500, 75%](upload://kEE0gcp2gmhi6p2Vnb2IkkuvVzS.png) ![Screenshot 2025-10-29 110130|288x500, 75%](upload://eBBDEz4BsIUadoDuw4vYdZkwps7.png) --- ## Post #2 by @skelly Hi, just to let you know the app is failing to load for me at the moment due to getting 404 on the .env file. --- ## Post #3 by @pacharanero Thanks @skelly I can repro same error by visiting https://rcpch.github.io/digital-growth-charts-app/ [details="error trace"] ``` digital-growth-charts-app/assets/.env:1 Failed to load resource: the server responded with a status of 404 () main.dart.js:31896 Error while trying to load an asset: Flutter Web engine failed to fetch "assets/.env".

I have definitely broken this but I’m a bit confused how - I think I did test it after I introduced the env file in October last year ( https://github.com/rcpch/digital-growth-charts-app/pull/37 ). Looking at the GH pages artifact there’s no .env in the root or assets folder. Also weirdly there’s a nested assets folder inside the assets folder. When I build the web package locally it is included, as per the [pubspec.yaml assets config](https://github.com/rcpch/digital-growth-charts-app/blob/fbc46bdd21af5290c5daac2ce329c936c46dd2be/pubspec.yaml#L95). Either way will fix, tracking in https://github.com/rcpch/digital-growth-charts-app/issues/63 --- ## Post #5 by @michael.barton It should be working again now, thanks again for reporting @skelly! I let Copilot update `actions/upload-pages-artifact@v3` from v3 to v4 and unfortunately they stopped including dotfiles for security reasons (https://github.com/actions/upload-pages-artifact/issues/129). I’ve downgraded it again for now since we don’t expect to keep the web build long term. And of course mea culpa, I should have checked it worked after the deploy - even though this is still a work in progress project! --- ## Post #6 by @g.jones8 Thank you for allowing me access to the app. I am a clinician in the NHS. Is this the right place for me to give feedback from a clinical perspective? --- ## Post #7 by @michael.barton Thanks @g.jones8, yes please do! Feedback always welcome. You can either reply to this forum topic or create a new one here: https://forum.rcpch.tech/c/rcpch-digital-growth-charts/digital-growth-charts-app/40 --- ## Post #8 by @g.jones8 Thanks Michael. This is a really good resource, thank you for developing it. I just have a couple of comments that might make it easier to use. 1. When entering the dates manually, it would be nice to be able to enter in UK format rather than US 2. When entering the dates using the calendar, would it be possible to have the option to select the month as well as the year instead of having to tab across the months? 3. Is it possible to add all the measurements - height, weight, head circ and BMI if known on the initial screen before submitting and moving on to the charts? This would make it easier rather than having to keep going back and entering the next one. 4. Can you include units of measurement on the initial screen also. I would have thought this would be cm for height and head circumference (or OFC) and kg for weight - as per the growth charts. 5. When you submit and move through to the charts section, it may be better to land on the table tab and then you have the option to look at the graphs if needed afterwards I hope this feedback is helpful. Thank you again --- ## Post #9 by @michael.barton Thanks Gabby, very very valuable feedback. I’m hoping we’ll be able to work some more on the app soon but it might take a few months to address some of it. Can I also just ask a couple of points of clarification to help us understand the different use cases for the app better: Are you tracking measurements over time or entering measurements for a single day to get the centiles etc? --- ## Post #10 by @g.jones8 In my practice I would be entering measurements for a single day to get the centiles, but it’s likely that other clinicians may want to plot a series of measurements to see the trend. --- **Canonical:** https://forum.rcpch.tech/t/digital-growth-charts-app-start-here/608 **Original content:** https://forum.rcpch.tech/t/digital-growth-charts-app-start-here/608
