Hi Anh,

Thank you for your honest feedback, and I'm really sorry you had trouble with the ruler feature. Your input is super important to us, and we've definitely taken it on board.

Since your review four years ago, we've totally revamped our features, including the ruler. It's now much smoother, with no freezing or scrolling issues. Plus, based on your suggestions, the rulers now come in different colors, and you can adjust their height, width, and position on your screen. We made these changes thinking about our users with developmental disabilities and how we can better serve their needs.

Here's some good news: the ruler feature is now completely free! We get how crucial it is to have dependable reading aids, so we're committed to making Helperbird as accessible as we can for everyone.

We'd love for you to give Helperbird another try and see how the new ruler feature works for you. If you have any more ideas or need help, just email us at support@helperbird.com. Your feedback helps us keep improving.

Thanks again for taking the time to review us. We're hoping to give you a much better experience with Helperbird this time around.

Best,
Robert James Gabriel
Helperbird Team
