Construction Snag List App With GPS Photo Evidence
Every photo automatically tagged with metre-accurate GPS coordinates. Pin snags to site drawings. Generate PDF reports with verifiable location data. Works offline on the native Android shell.
Verifiable Evidence for Every Snag
Auto GPS Tagging
Every photo is automatically tagged with metre-accurate coordinates. The accuracy level is displayed per capture so you know exactly how precise the location data is.
Offline Photo Capture
On the native Android shell, coordinates are cached locally even without signal. Photos, GPS data, and snag details sync automatically when connectivity returns.
Professional Reports
PDF audit reports include GPS coordinates alongside photo evidence. Excel exports provide the full dataset with location data, timestamps, and contractor assignments.

Frequently Asked Questions
Does GPS work inside buildings?
GPS accuracy varies inside structures, but ProPlot displays the accuracy level per capture so you always know the precision. For interior snags, the drawing pin feature lets you mark exact locations on uploaded floor plans as a complement to GPS data.
Can contractors see GPS data?
Yes. When you share snag items via trade-filtered links, contractors see the photo evidence, location data, and drawing pin positions. This helps them locate the exact issue before arriving on site.
Are GPS coordinates stored securely?
Yes. All location data is stored securely in your project database and only accessible to you, your team, and contractors you explicitly share with. GPS data appears in exported reports for compliance purposes.
