— 03 / Problem What you're choosing between
Three bad options, every single survey.
A five-to-fifteen-person shop measuring windows in 2026 is stuck picking the least-worst tool. None of them were built for the van.
The app that disappeared.
iwindoor is no longer on Google Play. Shops that still use it keep an old install alive and hope the next Android update does not break it.
The office software.
Industry software for window makers lives on the office desktop: orders, production, cutting lists. On site, the measurements still go onto paper first and get typed in later.
The clipboard cost.
One transposed digit on a paper sketch and a window is built to the wrong size. A re-make is paid for twice: the second frame and the second trip to site.
— 04 / Product What Frametap does
Six things, done properly. Nothing else.
The goal isn't to replace your ERP. It's to replace the moment in the van where someone types numbers off a paper sketch into a spreadsheet and nobody catches the typo.
Designer in your pocket
Sketch any window: mullions, transoms, sliding panels, French doors, arched heads. Touch-first — the same fluency a draughtsman gets with a pencil, on a phone, in the rain.
One photo per window
The production team sees the brick reveal, the lintel, the existing trickle vent — exactly what the measurer saw. Photos attach to the measurement, not to an email someone forgot to forward.
Survey report PDF
The customer's details and the date on the cover, a survey list from two windows up, then every window with its drawing, dimensions, spec and photos. With Pro: your logo and company details instead of the Frametap mark. Sent to the office before you leave the site.
Works offline. Always.
Measure in basements, attics, half-built construction sites. No bars, no problem. With Pro, everything syncs the moment you're back online.
PVC, wood, aluminium
Pick PVC, wood or aluminium, then record what production needs: profile system, outside and inside colour, handle finish, glazing for each pane, the Uw value and notes. All of it goes into the PDF with the drawing.
GDPR-compliant cloud
Surveys, photos and accounts live in an EU data centre in Paris, and the photos in a private bucket that is never public. Every company that helps run Frametap is named in the privacy policy — the ones based in the US work under the EU–US Data Privacy Framework or standard contractual clauses.
— 05 / Comparison Paper or the phone
The same survey, without the retyping.
Side by side with what most shops still use on site: a paper sketch, typed into a spreadsheet back at the office.
| Frametap | Paper + Excel | |
|---|---|---|
| Sizes | Typed once, in millimetres, on site | Written down, retyped in the office |
| Drawing | Mullions, transoms, arches; 11 opening types per sash | Freehand sketch |
| Photos | With each window | Somewhere in the camera roll |
| Spec | Material, profile system, colours, handle, glazing, Uw, notes | Margin notes |
| Hand-over | Survey PDF, shared by email or WhatsApp | A photo of the sheet |
| Quote | Pro: from your own price list, with your logo | Worked out in the evening |

— 08 / FAQ For the record
Yes. Frametap is an alternative to iwindoor for surveying windows and doors on a phone. It runs on Android and iOS, works offline on site, records the material, profile system, colours, glazing and Uw value of each window, and with Pro keeps one account in sync on every device, with the data in an EU data centre in Paris. The free plan needs no card; Pro is €29 a month or €290 a year per shop.
Frametap's free plan costs nothing and needs no card: one active project with up to 3 windows, and the survey PDF carries a Frametap footer. Pro is €29 a month or €290 a year per shop, not per surveyor — unlimited projects and windows, sync on every device on your account, quotes from your own price list, and your logo and company details on the PDF instead of the Frametap mark. Every new shop gets 14 days of Pro to try it.
The fastest path is a touch-first mobile app the surveyor uses on site: sketch each window, attach a photo, capture the material and glazing spec, then send the survey PDF to the office before leaving. Frametap is built specifically for this workflow, offline-first, so nothing is retyped off a paper sketch.
Now. Frametap is live on the App Store and on Google Play. The free tier needs no card, and every new shop gets 14 days of Pro.
