Start a survey
Create a project with the + button, then add your forms. Changes are saved on this device. The demonstration forms let you try menus and features; your experiments reset when you leave that project.
Dimensions and units
Choose the project country and units. In Regional technical fields, Based on country suggests the fields for window and door entries; a manual selection replaces them without deleting entered data. Existing projects keep their manual selections; changing the country restores Based on country. In Settings, this selection applies only to new projects. Enter the region or subdivision once per project. DD means back of frame, HT overall and TF finished opening; frame extensions are included in HT dimensions. Glazing component units remain independent of the window or door dimensions. Check conversions and the manufacturer's conventions before ordering.
Customize the sketch
Choose a template and its options. Dual colour records the interior and exterior finishes; the preview shows the inside. Returning to one colour retains the exterior finish for later reactivation. Set glazing bars, crossbars and infills by area. In Glazing bars, Duplicate to… copies the source pane’s settings to the selected destinations; All other sashes makes selection easier. The destinations’ glazing bars are replaced, then each area remains independent. Check the preview, especially if an axis position has been adjusted. Ventilation grilles are marked in red on dark interior finishes and black on light finishes; this does not change any RAL value. Annotate with your finger or Apple Pencil. After changing dimensions, use Update proportions and check annotation positions: freehand strokes do not automatically follow the elements. The previous sketch remains recoverable; an older image can serve as a reference when recreating annotations. Displayed colours are indicative.
Glazing and local variants
The Glazing field remains free text. Choose offers examples for the 29 supported countries, including 4/20/4 in Europe. Refine specifies panes from outside to inside, gaps, gases, spacers and coatings. Choose mm or inches independently of the dimensions; retain the manufacturer’s nominal designations and codes. Choosing another example retains other details; a favourite recalls its saved configuration. Favourites and recent items remain available. Explicitly distinguish Existing and Requested and customise areas if needed. Appearance, notes, declared performance and evidence remain separate; examples calculate no rating or performance.
Air inlets and sashes
Keep the free-text ventilation description or open Air inlets. Enter presence, regulation, nominal or minimum and maximum airflow, then the manufacturer’s unit and reference pressure. Equivalent area and acoustics are recorded separately. Select sashes from the inside: left and right, or numbered left to right then top to bottom. Same vent shares settings; turn it off to configure vents individually. Small bars mark inlets on the upper rail below the transom. Specify other positions in the details.
Toplights, lower panels and assemblies
In advanced settings, enter the toplight height from the top, the lower panel height from the bottom and the side element widths. These dimensions are included in the unit size, not added to it. Configure composite units by row, column and element: tap the sketch to select an element, then choose its opening or shape. Add up to eight horizontal transoms and eight vertical mullions per zone, then configure each filling. Check dimensions and complete special shapes before ordering.
Project and entry preferences
Project preferences apply to frames in all its revisions; changing a preference in a form creates an exception. Use project defaults again reinstates the shared values. In Refine, the Warm Edge choice can follow the project or be set for the form. This request is not automatically applied to Existing glazing. Recorded spacer characteristics remain separate; check the information if it differs from the Warm Edge choice.
Revisions, order and trash
Create a revision to keep another version of the survey. Reorder entries within a project to set their reading and export order. Deleted projects and revisions remain in the trash, where you can restore them.
Prepare and share the PDF
Choose A4 or Letter and Portrait or Landscape in the app options. Each form starts on a new page, with continuations if needed. Check dimensions, sketches, finish faces, glazing and air inlets before sharing. Variable scale means the sketch is not a fixed-scale print drawing. Check the recipient: a received PDF remains with them after the project is deleted.
Send a structured export
In settings, open Structured export, select projects and revisions, then whether to include contact details and photos. The JSON sends recorded data and details to compatible software through the iOS share sheet. This is a data exchange, not a backup that can be reimported into WDS. No WDS server or permanent remote access is created. Check every transfer: the app cannot recall a copy already received.
Use projects on two devices
Use the same personal iCloud account on your iPhone and iPad, with iCloud Drive available. You can work offline; syncing resumes when possible. Close the entry and check sync status before switching devices. Check Recovery if concurrent edits have been preserved.
LiDAR and preliminary estimates
Open LiDAR and slowly scan the opening and surrounding wall. Select a detected window, door or opening, then check width and height before applying them. The information badge explains the limits. If detection fails, measure edges manually; arch rise requires edge measurement or manual entry. Results are for initial estimates and must be checked with a tape or laser before ordering or manufacture.
Dictate and review
Dictation follows the app language, including regional variants. Say field names and units, then analyse and check each proposal before applying it. On-device dictation must be available for that language; you can also type or edit the text. The app does not retain audio.
Dimensioned LiDAR photos
Frame the entire opening before selecting it. The dimensioned photo is previewed before confirmation and added to the item's photos if enabled. Cancelling saves no photo. The five-photo limit per item still applies.
Photos and privacy
Frame only the window or door needed for the quote. Avoid people, documents and private belongings; ask permission to photograph the premises.
Protect your work
Keep your device locked and up to date. Export important surveys before an update, uninstalling or changing your iCloud account. Sync and the trash do not replace an independent backup.
