Plot Digitizer vs Research Lab Hub

Plot Digitizer is an app to extract numerical data from plot images. It is often necessary to obtain original (x, y) data from graphs, e.g. from scanned scientific plots, when data values are not available. Plot Digitizer allows you to easily get the numbers in such cases. Digitizing is a nine-step process: 1. Open a picture or take a photo of the plot; 2. Crop the picture to isolate the plot; 3. Align the plot, if required; 4. Do some fine-tuning cropping, if required; 5. Set the X and Y axes anchor points using your finger or an Apple Pencil; 6. Adjust the Axes Titles and anchor points; 7. Digitize the data series using your finger or an Apple Pencil; 8. Label the data series; 9. View, export the digitized data or view fitted equations. At the end of the process, you can copy the data to the clipboard, share it with another app, view a digital plot or fitted equations from the digitized data.

Research Lab Hub is a comprehensive mobile platform designed for academic research laboratories. Built for university supervisors, researchers, postdoctoral researchers, PhD candidates, and undergraduate students, it centralises every aspect of lab operations into a single, intuitive app. For Supervisors and Lab Managers: Manage your entire research group from your phone. Review and endorse student logbook entries, monitor individual progress milestones, assign tasks, schedule lab meetings, manage shared instruments and inventory, and broadcast announcements to the whole team — all in one place. For Students and Researchers: Keep a structured digital research logbook, track your milestones and deadlines, manage your personal task list, stay informed of lab announcements, and request role changes as you progress through your academic journey. Key Features: • Research Logbook — Submit daily or weekly research entries for supervisor endorsement. Advisors can approve or return entries with written feedback. • Progress Monitoring — Track research milestones, completion percentages, and upcoming deadlines with a clear visual timeline. • Task Management — Personal and lab-wide task lists with priority levels, due dates, and completion tracking. • Lab Schedule — Shared calendar for lab meetings, seminars, instrument bookings, and important events. • Instrument & Inventory Management — Log laboratory instruments, track usage, and manage consumable inventory levels. • Meeting Minutes — Record, store, and share meeting minutes with all lab members. • Announcements — Advisors can broadcast important notices to the entire lab instantly. • Member Management — Invite members via unique 8-character codes, manage roles, and approve role change requests. • Join Lab via Invite Code — Students who registered independently can join an existing lab at any time by entering their supervisor's invite code in Settings. • Backup & Restore — Export and import all personal data as a secure JSON backup file. • Dark Mode — Full support for iOS system dark and light mode. • Secure Authentication — Email and password registration with role-based access control.
