Hi,

On the hardware side, you will need something like an Arduino with WiFi (some of MKR or Nano33 series for example), or ESP8266,or Raspberry, or something other that can connect to the internet. You can also go the route of using a Bluetooth module like a HC05. These are only some of the options, there are much more of course. For the sensor itself, you can find scale sensors with a HX711 amplifier circuit.

On the software side, you can go with Blynk from the playstore or some app that focuses on reading data from Thingspeak. Or you can make your own easily using MIT App Inventor II.

I did a project where I uploaded scale weight data to an app I made, I went step by step for everything in this blog: S.H.E.L.F. V2 .

I think you will find everything you need there, but, if you just want to read scale data, you can also use Blynk, which is an easy way of getting something like an Arduino to talk to an app in which you have drag n drop elements. You can find a lot of tutorials on that on YouTube, I played a bit with that, you might find it useful: Ski Lamp

Hope this helps!
