OpenThis is a small app-discovery website that publishes five source-linked picks each weekday. These are five concrete jobs from our archive, with links to the product sources checked on 12 October 2026. This is a documentation review, not a performance benchmark or a ranking.
1. Put the reference beside your editor
Rectangle moves Mac windows to halves and corners with shortcuts or edge snapping. The free, open-source app covers a browser-and-editor layout on macOS 10.15 and later. Restoring a saved workspace of several apps needs Rectangle Pro, whose current version requires macOS 13.5 or later. Pro has a 10-day trial; check its checkout for the current license price.

2. Explain a layout bug on the screenshot
Shottr captures a Mac screen, measures gaps and adds arrows or notes. It also supports scrolling captures and text extraction. It requires macOS 10.15 or later. Free personal use has upgrade reminders after 30 days; commercial work requires a license. Basic is $12 once and Friends Club $30 once. Uploading needs activation.
Sources: Shottr features and licenses.
3. Read the API reference when offline
Dash searches documentation stored on your Mac. Download the language and framework docsets before losing the connection; new downloads and updates still need internet access. The current purchase route is Dash Yearly. Its France checkout showed €20 per year before VAT and €24 including VAT, renewing yearly. Other regions may differ. We have not benchmarked search speed or tested offline coverage for every docset.
Sources: Dash and subscription.
4. Inspect the request behind a failed app action
Proxyman shows request headers, bodies and responses. Its desktop app runs on Mac, Windows and Linux. Breakpoint editing requires a paid license; it is excluded from free evaluation. Standard is $89 once for one desktop seat, with one year of updates, and tax may apply. Capturing iPhone HTTPS traffic through the desktop proxy needs network and trusted-certificate setup. Certificate pinning can prevent capture.

5. Commit a small repository change from an iPad
Working Copy can clone, edit and commit a repository locally. Files integration lets another editor work on the files. Pushing needs Pro and a connection. The current store version requires iOS or iPadOS 18.2 or later. The US Pro unlock is $35.99 once with a 10-day trial; existing unlocked features remain available, with new Pro features included for 12 months. Regional prices differ.

Try two editions of OpenThis
If you regularly discover software, we are also looking for eight adult volunteers to try two OpenThis Daily Five editions. The proposed dates are Monday 19 and Tuesday 20 October 2026, subject to confirming the eight participants before starting.
Use the same device and browser for both visits. Open, save or pass actions are optional. No purchase, account or newsletter signup is required. A random browser-local identifier lets us match visits, with no names or email addresses in those events. There will be no reminder between visits.
If interested, reply with the last app you discovered, when and where you found it. We will confirm eligibility, the dates and written agreement before privately sending the starting link. The public site is OpenThis. Declining is fine.
Prepared with AI assistance. Features, prices and limits were checked against the official sources linked above; this does not establish hands-on performance results.
