Step 1
Snap a photo
Photograph the job you want to start, price up, or review.
Step 2
Derek works it out
Tools, ordered steps, real prices, and quality checks, in seconds.
Step 3
Decide with confidence
Know what to DIY, what to quote, and what to challenge.
What you get
One app for the whole job, start to finish.
From a photo to a real plan
Photograph the job and get clear, ordered steps, the exact tools and materials, time estimates, and the safety gotchas that actually matter.
- Ordered, time-boxed steps
- Tool and material lists
- Safety warnings up front
See DIY cost against a trade quote
Every estimate puts the itemised DIY material cost next to a typical UK tradesperson quote, so you know exactly what you save by doing it yourself.
- Itemised UK material pricing
- Typical trade quote range
- Rent-or-buy tool guidance
Matched to your skill level
Beginner, intermediate, or pro. Derek tailors the detail, from every step spelled out to just the specs, tolerances, and trade tools.
- Three experience levels
- Detail tuned to you
- No jargon unless you want it
A second opinion on finished work
Photograph completed tradesperson work for a 1-to-10 quality score and an honest check on whether the price you paid was fair.
- Quality score out of ten
- Fair-price assessment
- What could have been better
