Field Ascend field service mobile app on a phone showing the technician job view with timer, photos, and materials for US contractors

Open a job, capture the work, complete it on site. Photos, signatures, time and materials — even with no signal.

Tired of paper job sheets? Apps that crash on site? Techs calling the office for the customer’s address?

There’s a better way.

Paper and clunky legacy field service tools weren’t built for the basements, rooftops, and dead zones your technicians work in every day. Field Ascend was built offline-first — so the job gets captured on site, every time, and syncs to your office the moment signal returns.

Built Offline-First — Actually Offline

Work queues safely on the device until it can upload
Auto-syncs to your office the moment signal returns

Common Questions

Straight answers to what contractors ask before they roll the app out to their team.

Does the app work offline?

Yes. Field Ascend is built offline-first from day one. Technicians can finish a whole job — photos, signatures, time, and materials — with no signal at all. The moment connectivity returns, everything syncs to your office automatically.

Is it on iPhone and Android?

Yes. Field Ascend has native apps live on both the iOS App Store and Google Play. It is a real native app, not a web wrapper, so it is fast and reliable on site.

Can I customize the app with my logo and colors?

Yes. The app and your customer-facing documents are custom-branded to your business — your logo and your colors — so everything your technicians and customers see reflects your company, not ours.

How long does the app take to set up?

It is designed for technicians, not IT teams. Your team downloads the app, logs in, and starts working — you can onboard a new technician in minutes. Most teams are running jobs the same day they sign up.

Do I need a credit card to start the trial?

Yes, a card is required to start your 30-day free trial, but you are not charged until the trial ends. Cancel anytime before day 30 and you pay nothing.

Is there a long-term contract?

No. Field Ascend is month-to-month. There are no annual lock-ins, no setup fees, and no per-module pricing. Cancel anytime.
