Best Preflight Briefing & Go/No-Go Apps (2026)

Home › Compare › Best Preflight Briefing Apps

There is no single best preflight briefing app; the best pick depends on the job. (Yes, FlightDecide is ours.) The short version: 1800wxbrief for the official, logged briefing (free, every pilot should have an account); FlightDecide for a go/no-go second opinion scored against your aircraft's POH numbers and your personal minimums; PlaneWX for planning days ahead; WeatherSpork for understanding the weather; and ForeFlight if you want briefing built into a full EFB.

The field at a glance

Two framing notes before the rankings. First, briefing and go/no-go apps complement an EFB; most pilots who use one of these also run ForeFlight or Garmin Pilot for charts, navigation, and filing. Second, the official channel is ranked first because a logged briefing is the one thing no third-party app provides.

1. 1800wxbrief (Leidos Flight Service): the official one, always free

1800wxbrief.com is the FAA-contracted Flight Service provider, available on the web and by phone. It isn't the prettiest tool on this list and it offers no scoring or decision layer. But it does something no third-party app can: it produces a logged official briefing that documents your compliance with 14 CFR 91.103's requirement to become familiar with all available information before flight. If an inquiry ever asks whether you were briefed, this is the record that answers it.

It's also genuinely useful, not just legally useful. The standard briefing is thorough, adverse conditions are surfaced first, and a phone briefer remains one of the best resources in aviation when the picture is genuinely confusing.

Choose it if: you fly at all. Every US pilot should have a free account here regardless of which apps they run.
Skip it if: never entirely. But if you want interpretation, scoring, or a verdict, you'll be layering one of the apps below on top.

2. FlightDecide: the go/no-go second opinion that knows your airplane

FlightDecide is a go/no-go decision-support app for iOS (Android is in development), and it occupies a slot nothing else on this list does: it actually does the math on your flight. It runs the fuel burn with Part 91 reserves, the weight and balance, and the runway and climb performance against your aircraft's POH numbers, reads the weather and NOTAMs for your departure window, and scores eight risk categories against your personal minimums to render a clear GO / CAUTION / NO GO. It is the only tool here built around your specific airplane and your own limits rather than a generic weather picture.

A few things set it apart in this field:

• It scores your actual airplane. Fuel, weight and balance, and runway/climb performance are computed from the POH data for your type and weighed against the minimums you set, not a one-size chart. Nothing else here does that.
• NOTAM honesty. FlightDecide distinguishes "we queried the source and found zero NOTAMs" from "we couldn't check." No other tool here surfaces that difference, and a blank NOTAM list that could mean either is exactly the silent failure that bites pilots.
• Real Canadian coverage. Canadian NOTAMs come from NAV CANADA's own CFPS data and the airspace layer tracks the current Designated Airspace Handbook cycle, so cross-border flying is a first-class case, not an afterthought.
• A briefing you can check. Alongside the scores you get a plain-language summary of why the verdict came out the way it did, shown next to the raw METARs, TAFs, and NOTAMs it drew from, so you can verify the reasoning rather than take it on faith.

The aircraft library ships with 42 POH-digitized types from trainers to jets (the same data behind our free aircraft performance pages), and Pilot-plan subscribers add custom profiles with their own minimums baked into the scoring. Pricing: free tier with 3 full analyses per month, Pilot at $9.99 USD/mo or $79.99 USD/yr for unlimited analyses plus custom aircraft, Pro at $19.99 USD/mo or $159.99 USD/yr for fleets. FlightDecide prices here are in US dollars. The App Store charges the equivalent in your own currency, so check the price shown in the app before you buy. There's also a free, no-signup suite of 11 pilot calculators on this site if you want a feel for how we think.

Choose it if: you want a second opinion that knows your airplane's actual numbers and your actual minimums, not generic weather commentary.
Skip it if: you need charts, navigation, or filing; that's EFB territory, and FlightDecide is built to sit alongside one.

3. PlaneWX: best long-range planning

PlaneWX (founded 2025, web app) attacks a different part of the problem: what the weather will let you do days from now. Its WX Score is a probability metric for a flight working out, paired with a PAVE-based risk assessment and planning out to 14 days, well beyond what any TAF-based tool can see. The free tier (2 flights, 15 briefings per week) runs the identical analysis to paid, which is a genuinely pilot-friendly way to structure a freemium product; the paid Casual and Pro tiers add automation: auto-refresh, alerts, a Flight Window Explorer, Corridor Watch, and a Multi-City Optimizer.

If your recurring question is "is Saturday's trip going to happen?", this is the strongest tool on the list, and its long-range view is something FlightDecide doesn't attempt. The trade-off is that it's web-based rather than a native mobile app, and it's a planning tool more than a morning-of verdict engine.

Choose it if: you plan trips days in advance and want probabilistic guidance on whether the window will hold.
Skip it if: you mainly decide the morning of the flight and want a native app on your phone.

4. WeatherSpork: best for weather education

WeatherSpork ($4.99 USD/mo or $49.99 USD/yr; iOS, Android, and web) is the work of Scott Dennstaedt, a former NWS meteorologist and CFI, and it shows. It's a strategic route-weather tool built to teach: the route-profile view lays out conditions along your track vertically and in time, and the whole product is oriented toward understanding why the weather is doing what it's doing rather than issuing a verdict about it.

It is deliberately not a verdict engine; you won't get a GO or NO GO out of it. But pilots who spend a season with it tend to get better at reading weather everywhere else, which is arguably the highest-leverage upgrade on this whole page.

Choose it if: you want to genuinely understand the weather picture, especially for cross-country and IFR flying.
Skip it if: you want a scored, thumbs-up-or-down answer; that's not what it's for.

5. ForeFlight: best full EFB with briefing built in

ForeFlight (Starter $130 USD/yr, Essential $260 USD/yr, Premium $390 USD/yr) is the standard American GA EFB, and it earns the position: charts, flight planning, filing, a graphical briefing, and a logbook in one polished app, with Essential and above adding synthetic vision and hazard layers. Its integrated briefing is well-organized and legitimately good; our detailed comparison is here.

The category note that applies to any EFB: it's the cockpit workhorse, not a decision advisor. ForeFlight presents the data brilliantly, but it doesn't score your flight against your minimums or tell you whether the combination of this ceiling, this crosswind, this NOTAM, and this density altitude adds up to a flight you should make. That interpretive step is still all yours, which is exactly the gap the decision apps above exist to fill. Most FlightDecide users also run an EFB, and that's the arrangement we'd recommend.

Choose it if: you want one app for charts, planning, filing, and briefing. It's the default answer for most US GA pilots.
Skip it if: you only want a briefing/decision layer; a full EFB subscription is overkill for that alone.

6. Garmin Pilot: best EFB for Garmin panels

Garmin Pilot (roughly $109 USD/yr standard, about $179 USD/yr Premium; iOS and Android) is the other big EFB, and if your panel is Garmin (GTN navigators, G3X, GI 275), its Connext integration with your avionics is a real advantage ForeFlight can't fully match. It's also the major EFB that runs on Android.

The same category note applies as with ForeFlight: excellent data presentation and planning, no verdict layer. It shows you everything and decides nothing, by design.

Choose it if: you fly behind Garmin avionics or want a full-featured EFB on Android.
Skip it if: same as ForeFlight. It's an EFB decision, not a briefing-app decision.

How we evaluated

We compared each product on its published pricing and feature set as of July 2026 (vendor websites and app-store listings; always confirm current pricing before subscribing), on the quality and verifiability of its data sources, and on how honestly its design handles uncertainty. A tool that admits what it couldn't check is safer than one that papers over gaps. We ranked by use case rather than crowning one winner, because "best" genuinely depends on whether the job is a legal record, a free VFR sanity check, an aircraft-specific verdict, long-range planning, education, or cockpit navigation. Throughout, we've tried to describe our competitors the way their happiest users would.
