For structural & civil engineers
Engineers Digital Hub is the most comprehensive engineering toolkit on Apple platforms: a family of offline apps built for real engineering days. The full hub for Mac, EDH Pocket for iPhone and iPad, and EDH CPD, the free app that logs your CPD by itself. Calculators, references, AI prompts and project records, working alongside your design software.

The desktop hub · Out now for Mac
Hundreds of ready-to-use prompts for everyday engineering tasks. Copy, tweak and paste into your AI of choice.
54 structural design checks for fast sense-checks, with full working and a clear pass / fail.
Standards, methods and worked precedent, searchable and at your fingertips.
Steel, timber and concrete section data, materials and a glossary: the numbers you look up all day, built in.
Open and review IFC models for a quick look, with no heavyweight BIM suite needed.
Redline drawings and spot the revisions between two issues, side by side.
Capture site photos and pull text straight off a scan or drawing.
To-dos, notes, registers and project records that keep the day's admin in one place.
No cloud and no account, so your projects stay confidential on your device.
Put your practice's logo and accent colour on the app and every calc sheet.
How it works
No setup, no account, no learning curve. Install it and it is ready.
The hub from the Mac App Store. Pocket and CPD from the App Store on iPhone and iPad.
Run a calc, look up a section, mark up a drawing, or grab a prompt for your AI.
Everything runs and saves on your device. Nothing leaves your machine.
Prompt assistant
Engineers Digital Hub is a prompt assistant. It comes loaded with a growing library of carefully written prompts for everyday engineering work: drafting a method statement, sanity-checking an approach, explaining a clause, writing up an inspection. Copy one, paste it into your AI of choice, and get a proper head start. Your AI does the talking, EDH gives you the right thing to say.
You are a senior structural engineer. I'm checking a 6 m simply supported steel beam under a 25 kN/m UDL. Walk me through the Eurocode checks (bending, shear, deflection and lateral torsional buckling) and flag anything I might be overlooking.
Calculations
Every check shows its full working, the clauses it draws on, and a plain pass / fail verdict, then exports to a branded calc sheet ready for the file.
Reference at your fingertips
Steel, timber and concrete section properties, a materials library and a glossary, searchable and offline, so you're not digging through PDFs or the blue book mid-calc.
Drawings & documents
Redline a drawing with clouds, arrows, notes and stamps, then compare two revisions side by side to see exactly what changed, and OCR a scan when you need the text back.

EDH Pocket · iPhone & iPad
EDH Pocket carries the same tool engine as the desktop hub, rebuilt for site. Run a design check at the kerb, open the model in the cabin, and let your CPD log itself on the train home.
Works offline apart from the news feed. AI features run on-device and need an iPhone or iPad with Apple Intelligence.
EDH CPD · iPhone & iPad
100% free, every featureEDH CPD turns spare minutes into evidence. Read a short section on the future of construction, check yourself with a quiz, and the hours record themselves. When review season lands, export the certificate and you're done.
Works offline apart from the news feed. AI features run on-device and need an iPhone or iPad with Apple Intelligence.
Why a hub
All the little frictions that slow a working day, gathered into one fast, offline place.
For practices & teams
Ten minutes a day lost to chasing references, refinding downloads, working around cloud access, rebuilding calcs and marking up adds up to roughly a working week per person, every year. Engineers Digital Hub puts that time back, on the desk and on site, and EDH CPD keeps the whole team's CPD evidence in order for free.
Free CPD for everyone. Pocket and desktop each come with a 14-day free trial, billed per user through the App Store. Cancel anytime.
No subscriptions, no unlocks, no ads. CPD for the whole team, at no cost.

The EDH family is built natively and exclusively for Apple platforms, and we believe it's the most comprehensive engineering toolkit you'll find there. The desktop hub is out now for macOS on the Mac App Store, and EDH Pocket and EDH CPD are on the App Store for iPhone and iPad. Going deep on one platform is what lets everything run fast, offline and on-device, with AI powered by Apple Intelligence.
Yes, genuinely. Every chapter, quiz, certificate and AI tool is included, with no subscriptions, no unlock purchases and no ads. It's our way of giving something useful to the profession.
They're deliberately independent, because neither app uses a cloud or an account. Pocket runs the same tool engine as the desktop, so your checks behave identically, and project records can be moved between devices with a simple one-file export and import.
Everything stays on your device. We don't run servers, we don't collect your project data, and there's nothing to sync to the cloud. The AI features in the iPhone and iPad apps run on-device with Apple Intelligence, so nothing is sent to us or anyone else.
Every check shows its full working and the clauses it draws on, so it can be independently reviewed and signed off. The calculators follow recognised structural design codes, including the Eurocodes with UK National Annex values.
Yes, on the desktop hub: add your practice's logo and accent colour, and it appears across the app and on every calc sheet you export.
Free CPD for everyone. The hub for desk and site, with 14-day free trials.
