CountThis is a free iPhone app developed by AIBY Incorporated that allows you to count similar objects via your phone camera. The app is suitable for people who deal with a lot of similar items on a daily basis, such as those working in the logistics and transport industry, as well as life-science professionals who need to count various kinds of devices and instruments, medicines, and supplies.

Using the app is simple: you take a photo of the objects you want to count, highlight one of them, and the app will give you the result. You can also manually add or remove objects to adjust the counting result. The app allows you to save the results and export them as PDF or JPEG files. It even lets you correct the results manually.

CountThis is not just for work purposes – it can also be used in everyday life. For example, you can use it to ensure that no puzzle pieces or LEGO bricks are missing, or to check if you have enough building materials for a renovation project.

One downside of the app is that some features are only available through a weekly or annual subscription, which can be a bit pricey for some users. However, the app itself is free to download and use, making it a great tool for anyone who needs to count similar objects quickly and easily.
