Comments on Change Detection for Android

★★★★★ Jay Reynolds · Sep 27, 2018
Bernardo, the developer, should be an example to all others. He worked diligently with me to isolate and correct a problem that only 2 people were having. I can't say enough good things about his work ethic and how much I appreciate him getting it going.
★★★★★ Chad Kumlien · Mar 16, 2019
This Dev is top-notch! The app is beautiful. The detection is solid. I had to reach out to Bernardo to understand how a site is not work. His response was super, he explained the technology and why the site doesn't play well.
★★★★☆ Robert Hassan · Feb 28, 2021
Good App, the only problem I have is that I keep missing the trigger notifications because the app does not provide a good and flexible way to deliver trigger notifications. In addition, as a value-added to the App; It would really help if the App would allow you to select a trigger section on the website to fixate your triggers on; nevertheless, it does detect when any changes are done to the web page. Thanks
★★☆☆☆ Ardianto S. Wijaya · Feb 2, 2019
Not working if the website used Cloudflare protection
★☆☆☆☆ Erik Neff · Nov 9, 2020
Would not recommend, generates lots of notification spam that effectively amount to false positives. I want the app to stay silent unless a meaningful change had occurred. In reality, I notified all the time just to say it checked and no update was detected. Furthermore, there was no way I could see to restrict what's being compared. These seem like fixable shortcoming, but in its current incarnation, it's not usable.
★☆☆☆☆ JD Zoska · May 1, 2019
15 m min interval, can't specify areas of a page to monitor
★★☆☆☆ No Name · Oct 23, 2019
Does the job just fine, but shortest interval is 15 minutes. Not very useful.

Description by Bernardo Ferrari Written by the developer, not by AppBrain. Click to read.
Change Detection allows you to monitor any website to receive notifications when it is updated. This app works natively, without the need for any external servers (your data is safe), using all the latest technologies, a great UI and it is open source.

Use cases:
- Teacher says grades will be published "soon", but no one knows what "soon" means and you are tired of reloading.
- You are working with a server and wants to know the result from a request, periodically.
- You are waiting for updates on an Exam, like if something was postponed or updated.

It also also showcases all the Android Architecture Components working together: Room, ViewModels, LiveData, Paging, WorkManager and Navigation.

When a change is detected on background, a notification (alert) is displayed. It currently doesn't work with login pages, but contributions are welcome. There are 3 viewers for the app, a text viewer that compares website history in a git-like way, with line by line added/removed and green/red, a pdf viewer which displays multi-paged PDFs on a carousel like interface, inspired by Lottie's open source sample app, and an image viewer, similar to the Pdf viewer, but with support for tiling (which allows heavy pictures to load faster and with lower memory).

Features:
✅ Notification when a website changes
✅ Monitor multiple websites
✅ Visual difference of all modifications (diff)
✅ Browse different versions of a site, PDF, image, or a text file.
✅ Does not require any permissions.
✅ Gradient color customisations for each item.
✅ Material design and latest Android Architecture Components.
❌Doesn't work with pages that require login.

Recent changes:
Backup functionality, new add/edit dialog, app size is 50% lighter and a lot of internal improvements.
