Before & After Photo App for Contractors
Before & after photos that prove your work.
Stop losing money to “you didn’t do that.” SiteProof turns your job site photos into timestamped, tamper-evident reports with client sign-off — documented, verified, and hard to dispute.
Free for up to 3 jobs · Pro is $9.99 once — no subscription · iPhone & iPad, iOS 17.1+
Download SiteProof free
Capture before/after photos, generate comparisons, and export PDF job reports — free for up to 3 jobs. One $9.99 purchase unlocks Dispute-Proof Mode, client sign-off, slider videos, your branding, HD export, and unlimited jobs. Forever.
Built for the job site
Every screen designed for gloves-on, one-handed use between tasks — from first photo to signed report.









How it works
Four steps between “I should document this” and a signed, verifiable job report.
Capture Before
Take a photo at the job site. SiteProof records the timestamp, GPS location, and street address automatically — no typing.
Do the Work
Your job is saved on your device. Come back anytime — even days later. Multi-task jobs keep every area organized.
Capture After
The ghost overlay shows your before shot over the live camera so the after photo matches the exact angle and framing.
Export & Sign
Generate a comparison image, slider video, or branded PDF report — and get the client’s signature right on your phone.
Other apps take photos. SiteProof makes them provable.
Everything a contractor, tradesperson, or property manager needs to document work — and nothing that needs an IT department.
Dispute-Proof Mode
Every photo is sealed with a cryptographic hash at capture. Any modification is detectable, and reports include verification details.
Client Sign-Off
Clients review the finished work and sign directly on your device. Signature, agreement, and timestamp are sealed together.
Professional PDF Reports
Client-ready reports with your logo and contact info, job details, before/after pages, and the client’s signature.
Slider Reveal Videos
10-second animated before/after videos that stop the scroll on Instagram, Facebook, and Google Business Profile.
Works Fully Offline
No account, no cloud, no signal needed. Your photos and client data never leave your device — private by design.
Pay Once, Use Forever
Free for up to 3 jobs. SiteProof Pro is a single $9.99 purchase — not $30+ per user per month like team platforms.

What is the best before and after photo app for contractors?
The best before and after photo app for a contractor is one that aligns both shots automatically, records timestamp and GPS, and exports client-ready reports. SiteProof does all three, adds cryptographic tamper-evidence and on-device client sign-off, and costs $9.99 once instead of a monthly subscription per user. Learn more →
How do you take before and after photos that line up perfectly?
Use a ghost overlay: SiteProof shows your original before photo as a semi-transparent layer over the live camera, so you can match the exact angle, distance, and framing for the after shot — even days or weeks later. It also auto-matches the torch to your before photo’s lighting. Learn more →
Does SiteProof add timestamps and GPS location to job photos?
Yes. Every photo is captured with the date, time, and GPS coordinates, and SiteProof reverse-geocodes the location into a street address automatically. That metadata flows into your comparison exports and PDF reports. Learn more →
Can SiteProof photos be used as evidence in a dispute?
SiteProof’s Dispute-Proof Mode seals every photo with a cryptographic hash at the moment of capture, so any later modification is detectable. You can export a complete evidence package — photos, PDF report, proof manifest, and client signature — as one verifiable ZIP. Strong documentation resolves most disputes before they ever reach court. Learn more →
How do I get a client to sign off on completed work?
Show the client the before and after photos in SiteProof, then hand them your iPhone or iPad. They review the work, type their name, and sign directly on screen. The signature, agreement text, and timestamp are sealed together and appear in your PDF report. Learn more →
Can I create a PDF job report with before and after photos?
Yes. SiteProof generates a professional US Letter PDF with your logo, company name and contact info, job details, before/after comparisons for every task, verification details, and the client’s signature — ready to share by email, Messages, AirDrop, or Files in seconds. Learn more →
Is there a photo documentation app without a monthly subscription?
Yes. SiteProof is free to download and use for up to 3 jobs, and a single $9.99 one-time purchase unlocks everything forever. Most alternatives like CompanyCam charge $30–40 per user per month, which adds up to hundreds of dollars a year for a solo contractor. Learn more →
Does SiteProof work offline? Do I need an account?
SiteProof works completely offline and requires no account. Your photos, jobs, and client data stay on your device — nothing is uploaded to a cloud. That means it works in basements, remote sites, and dead zones. Learn more →
How do I make a before and after slider video?
Pick any task in SiteProof and choose the Slider layout: the app renders a 10-second MP4 where a slider sweeps across the image, revealing the after photo over the before photo. It’s the highest-engagement format for Instagram, Facebook, and Google Business Profile posts. Learn more →
Is SiteProof good for landlords and property managers?
Yes. Landlords and property managers use SiteProof to document move-in and move-out condition, turnover cleaning, and maintenance work with timestamped, tamper-evident photos — increasingly important as laws like California’s AB 2801 require photo documentation of deductions. Learn more →
