Best Free Electrician Apps with Offline Mode and GPS (2026)
Free, Offline, and Built for the Van
If you're an electrician searching for an app, you're usually trying to solve three problems at once: keep costs down (free or cheap), keep working when the signal drops (offline mode), and get from job to job without doubling back (GPS and routing). Most "best apps" lists pretend the first two don't matter. They do.
This guide focuses on apps that tick all three boxes — or get close enough that the trade-off is worth it. We've checked free tiers, confirmed which features survive airplane mode, and noted which ones do GPS routing properly rather than just dropping a pin on a map.
If you only want a deep-dive on offline tools, our best offline electrician apps guide goes further on that single axis. If you want the broader pick of paid and free apps without the free/offline/GPS filter, see the best apps for electricians roundup. This page is the intersection.
Comparison Table: Free Tier, Offline, GPS
A quick scan before the detail. "Free tier" means a genuine free plan, not a 14-day trial. "Offline" means core job functions work without signal. "GPS" means routing or live location features, not just a static address field.
| App | Free Tier | Offline | GPS / Routing | Best For |
|---|---|---|---|---|
| Joist | Yes | Partial | Address only | Solo sparks, invoicing |
| Tradify | 14-day trial | Strong | Job map + directions | UK solo & small teams |
| Knowify | 14-day trial | Limited | Address only | Contract-heavy electrical work |
| Housecall Pro | No (paid only) | Limited | Strong routing | Service-based teams |
| Jobber | 14-day trial | Partial | Strong routing | Multi-engineer teams |
| ServiceTitan | No (enterprise) | Limited | Strong routing | Larger contractors (US) |
| simPRO | No (demo only) | Strong | Live tracking | Commercial electrical |
| Workiz | Free starter plan | Partial | Live GPS tracking | Small service teams |
| ServiceM8 | Free up to 20 jobs/mo | Strong | Job map + routing | Solo / micro teams |
| Connecteam | Free up to 10 users | Partial | Live GPS for staff | Team time tracking |
| Square Appointments | Free (solo) | Limited | Address only | Bookings & payment |
| Fergus | 14-day trial | Partial | Job map | NZ/UK trade businesses |
What "free" actually means
The Detailed Reviews
1. Joist — The Genuinely Free Pick for Solo Sparks
Free tier: Yes — estimates, invoices, and client management on the free plan
Offline: Partial — draft estimates and invoices work offline, sync on reconnect
GPS: Address fields with map preview, no routing
Best for: Solo electricians who want a free invoicing app that doesn't nag
Joist is the closest thing to a permanently free invoicing app in the trades. Create estimates, convert them to invoices, attach photos, take card payments (with a fee). The paid Joist Pro tier adds QuickBooks sync and custom branding, but the free version is genuinely usable as your main invoicing tool. Offline support is limited to drafts — you can write a quote in a basement, but sending it waits for signal.
2. Tradify — The UK Trade Standard
Free tier: 14-day trial, then from £29/user/month
Offline: Strong — job details, time logging, quotes, invoices, photos all work offline
GPS: Built-in job map with directions through Apple/Google Maps
Best for: UK solo electricians and small teams who need job management plus routing
Tradify isn't free, but it's the closest thing to a single app that does everything — and the offline support is genuinely good. The job list shows pins on a map, you can tap through to turn-by-turn directions, and the whole thing keeps working when you lose signal halfway down a country lane. Not on this list as a free option, but included because the trial is long enough to decide and the offline + GPS combo is rare done this well.
3. Knowify — Contract-Heavy Electrical
Free tier: 14-day trial, plans from $99/month
Offline: Limited — web-first, with a mobile companion app for field updates
GPS: Address-only on jobs
Best for: Electrical contractors running AIA-style contracts and progress billing
Knowify is for the contracting end of electrical work — change orders, retention, progress invoicing. Not a fit for a solo domestic spark. Worth knowing about if you're doing commercial fit-outs and need contract management. Offline support is weaker than the field-first apps because the bulk of the value is in the back-office workflow.
4. Housecall Pro — Strong Routing, No Free Tier
Free tier: No — plans from $49/month
Offline: Limited — viewing jobs works, edits sync when signal returns
GPS: Strong — built-in routing, live technician tracking on team plans
Best for: US-based service electricians on small teams
Housecall Pro is US-centric and very polished for service businesses. The routing is one of the best in this category — it sequences jobs, accounts for time windows, and live-tracks vans for the office. No free tier and no plans for one, so it's on this list as a comparison rather than a recommendation if "free" is non-negotiable.
5. Jobber — Multi-Engineer Teams
Free tier: 14-day trial, plans from £33/month
Offline: Partial — jobs and customers cache, edits queue and sync
GPS: Strong routing, technician tracking on higher tiers
Best for: Small electrical teams who dispatch multiple engineers
Jobber sits between Housecall Pro and Tradify. The routing is solid, the team scheduling view is one of the better ones in the trades category, and there's a decent UK presence. Like the others in this group, the free option is a trial, not a forever plan.
6. ServiceTitan — Enterprise Only
Free tier: No — enterprise pricing, contact sales
Offline: Limited — field service mobile app caches assigned work
GPS: Strong fleet routing and tracking
Best for: Multi-van electrical contractors (mainly US)
Mentioned only so the comparison is honest. ServiceTitan is the heavy-hitter for larger electrical contractors but it's expensive, US-focused, and overkill for anyone under five engineers. Not free, not really an option if budget matters.
7. simPRO — Commercial Electrical
Free tier: No — demo only, custom pricing
Offline: Strong — field mobile app works fully offline
GPS: Live van tracking and route planning
Best for: Commercial and industrial electrical contractors
simPRO is built for commercial trade businesses — project costing, asset maintenance, planned preventative maintenance schedules. It's in the comparison because the offline-on-site mobile app is genuinely strong, but it's overkill (and over-budget) for solo and small teams.
8. Workiz — Free Starter Plan with Live GPS
Free tier: Yes — Starter plan for up to 2 users
Offline: Partial — viewing and basic edits work offline
GPS: Live GPS tracking included even on the free tier
Best for: Small electrical service teams who want dispatch and tracking on a budget
Workiz is the most interesting genuinely-free option on this list if you have one or two engineers. The Starter plan includes scheduling, invoicing, and live GPS tracking. Offline support is the weak point — you can view scheduled work and capture basic updates, but heavy editing wants signal. Worth a serious look if you currently track your van on text messages.
9. ServiceM8 — Free Up to 20 Jobs a Month
Free tier: Yes — up to 20 jobs per month, then per-job pricing
Offline: Strong — built mobile-first, works fully offline and syncs back
GPS: Job map, turn-by-turn directions handoff
Best for: Solo electricians and micro teams under 20 jobs/month
ServiceM8 is the single best free pick on this list for an electrician doing under twenty jobs a month. It's a proper job management app — quotes, scheduling, photos, signatures, invoicing — and the offline mode is among the best in the category. The 20-job free tier is genuinely usable for a part-time spark or someone running fewer, larger jobs. Once you go past that you're on pay-per-job pricing, which works out cheap if you keep volumes moderate.
“I run about 15 jobs a month doing rewires and consumer unit swaps. ServiceM8 covers everything for free at that volume, works in the loft with no signal, and pings me directions when I'm heading out. Tried Tradify, liked it, but couldn't justify £30 a month over this.”

10. Connecteam — Team Time Tracking with GPS
Free tier: Yes — Small Business plan free for up to 10 users
Offline: Partial — clock-in and basic forms work offline
GPS: Live GPS on staff clock-ins (geofencing on paid tier)
Best for: Electrical teams wanting time tracking, schedules, and check-ins without paying per user
Connecteam isn't a job management app — it's a workforce app. Time clock, shift schedule, internal chat, training modules. For an electrical firm with multiple engineers, the free-up-to-10 plan is genuinely useful for time tracking with location stamps, and pairs well with a separate invoicing tool like Joist.
11. Square Appointments — Free Bookings for Solo Sparks
Free tier: Yes — free for solo operators
Offline: Limited — works best with signal
GPS: Address fields, no routing
Best for: Solo electricians taking online bookings and card payments
Square Appointments is the booking front-end. Customers self-book a slot, Square sends reminders, and you take card payment with the same account. Not a job management app, and the offline story is weak, but the free tier for solo operators is a legitimate way to add online booking and card payments without paying for both separately.
12. Fergus — NZ Roots, UK Following
Free tier: 14-day trial, plans from £30/user/month
Offline: Partial — field mobile app caches active jobs
GPS: Job map view with directions handoff
Best for: Trade businesses that have outgrown spreadsheets
Fergus is closer to Tradify than Jobber — built for trades, with a visual job pipeline (the "status board") that some sparks swear by. Worth including because UK adoption has grown, and the offline + map combo is decent. Not free past the trial.
Apps we left off
How We Chose
Three filters, applied in order:
Free tier or generous trial
An app with no free option had to bring something the free ones don't — either best-in-class routing, best-in-class offline, or a category nobody else covers. Most of the priority went to apps with a genuine free plan: Joist, ServiceM8, Workiz, Connecteam, Square Appointments.
Offline mode that survives a real day
We tested core flows in airplane mode: open a job, edit it, add a photo, write a quote, log time. Apps that crashed, hid the data, or lost edits on reconnect got marked down. ServiceM8 and Tradify lead this category. Most others are partial — fine for a quick look-up, not for a full off-grid day.
GPS that does more than display an address
A static address field is not GPS. We looked for job maps, route sequencing, turn-by-turn handoff, and where relevant, live van tracking. Workiz and Housecall Pro lead on routing; ServiceM8 and Tradify do a more modest but still useful version.
The Gap Every App on This List Has
None of these apps answer your phone.
An electrician's day is hands-in-the-consumer-unit, gloves-on, ladder-up, signal-bouncing-off-stone-walls. Even the apps with the best offline mode and the smartest routing can't pick up a ringing phone for you. Miss the call, miss the job — and on average, missed calls translate to lost revenue at a rate most sparks underestimate (the maths is in our how much do missed calls cost piece).
This is where a cloud-based phone receptionist sits next to the job management app rather than competing with it. VoxBot answers the calls your hands can't — on a number that works whether your own phone has signal or not. The caller gets a real conversation, you get a structured summary the moment you're back in the van. It's the half of the workflow the apps in this list don't cover.
VoxBot — The Other Half of the Stack
Free tier: Free trial, plans from £45/month
Offline: Cloud-based — works independently of your phone's signal
GPS: Not applicable — it's a phone receptionist, not a routing app
Best for: Electricians who lose work to missed calls while they're mid-job
VoxBot answers inbound calls 24/7, asks the right qualifying questions for trade work (urgency, location, job type), and sends you a summary by SMS or email. Pair it with ServiceM8 or Workiz for the on-job side, and you've got the rare combo of free-ish job management plus a phone line that never goes unanswered.
Recommended Free-First Stack
| Need | Free Pick | Step Up |
|---|---|---|
| Job management (solo, low volume) | ServiceM8 free tier | Tradify (£29/mo) |
| Invoicing only | Joist free | Tradify or Jobber |
| Team time tracking + GPS | Connecteam free | Workiz paid |
| Live GPS tracking | Workiz Starter | Housecall Pro / Jobber |
| Online bookings | Square Appointments free | Built into Jobber / Housecall Pro |
| Phone receptionist | VoxBot trial | VoxBot from £45/mo |
A solo spark can run a complete business on ServiceM8 free, Joist free for overflow invoicing, and a VoxBot trial — for £0 a month until job volume justifies stepping up.
