Best Estimating App for Contractors According to Reddit (2026)
The short answer
If you want to go from describing a job to a priced, itemized estimate in minutes, Takeoff Convert is the most direct app, it prices labor and materials with cited sources and learns your own numbers over time, from $29/mo with a free tier. Joist is the simplest free option for quick mobile estimates, STACK is the standard if your real need is on-screen takeoff measurement, and Buildertrend only makes sense if you also want full project management.
"Estimating app" means different things depending on your trade, some people want to measure off a plan, others just want to turn a walkthrough into a number they can send. This is an honest rundown of the apps contractors mention most, grouped by what they're actually good at so you don't pay for a measurement suite when you just need a fast quote.

The picks
Takeoff Convert
Free, then $29–$99/moTop pickAI that turns PDF takeoffs & estimates into finished proposals
Describe or upload the job and it produces an itemized estimate with labor and material prices, each line showing where the price came from, then turns it into a proposal. Best when your bottleneck is pricing and writing, not measuring.
Joist
Free–$39/moSimple mobile invoicing & quick estimates
Free and fast for simple line-item estimates from your phone on-site. Light on sourced pricing and scope language, but hard to beat for quick residential quotes.
STACK
Custom (≈$2,499+/yr)Dedicated cloud takeoff & estimating (measurement, not proposals)
The go-to for on-screen takeoff and measurement off plans. Produces quantities and estimates, though you'll write the client-facing proposal separately.
Contractor+
Free–$99/moField-service & job-management app for crews
Bundles estimating with job and crew management, reasonable if you want one app for the whole job rather than the best estimate specifically.
Buildertrend
$199–$499/moAll-in-one construction project management suite
Estimating is a small part of a full project-management suite, worth it only if you need the whole platform and can absorb the price.

FAQ
What is the best estimating app for contractors in 2026?
It depends on your bottleneck. If pricing and sending the estimate is the slow part, Takeoff Convert goes from a job description to a cited, itemized estimate in minutes from $29/mo. If you measure off plans, STACK owns that step. For quick free mobile quotes, Joist is the common pick.
Is there a free estimating app for contractors?
Yes. Joist and Contractor+ have genuinely free tiers for simple estimates, and Takeoff Convert lets you price a few jobs free before subscribing. Free tiers are usually capped on volume or features, so they suit occasional or very small jobs best.
What's the difference between an estimating app and takeoff software?
Takeoff software (like STACK) measures quantities off a drawing. An estimating app turns quantities or a job description into priced line items. Some tools do both steps; Takeoff Convert focuses on the pricing-and-proposal half and can take your numbers from any takeoff.
