Tachbase is an electronic flight bag (EFB) for general aviation pilots — preflight planning, in-cockpit awareness, and logging in one fast, offline-first app for iPhone, iPad, and the web. TACHBASE ASSISTANT Ask in plain English — "Any NOTAMs at KSFO?", "Cat A minimums for the RNAV 31 at KPAO?", "Am I night current?" — and get answers looked up live, not from memory: weather, PIREPs and winds aloft; runways, crosswinds and Chart Supplement remarks; approach fixes and minimums from the plate; the FAR/AIM and FAA handbooks; and your own logbook, currency and aircraft. Runs on Tachbase's own servers — your questions never go to a third-party AI. Aviation only; sign in for your own records. Advisory, not an official briefing. FREE — EVERYTHING INCLUDED No subscription, nothing to buy. The moving map, charts and georeferenced plates, in-flight tools, and offline downloads all work without an account. Create a free account and nothing lives on one device: your logbook, flights, plans, aircraft, and checklists sync across iPhone, iPad, and the web. MOVING MAP Airports, airspace, navaids, fixes, airways, and MTRs — tap any feature for details. Airport diagrams draw on the map as you zoom in. Overlay VFR/IFR charts, live weather (radar, satellite, winds aloft, PIREPs, AIRMETs/SIGMETs), TFRs, and your route. Download states & territories offline. CHARTS & PLATES FAA approach plates, departure/arrival procedures, airport diagrams, and takeoff/alternate minimums — plus taxi diagrams where the FAA has none. Plates are georeferenced (your aircraft draws on the chart); drop any chart onto the map. AIRPORTS Frequencies, runway wind analysis, METARs/TAFs, NOTAMs, fuel & services, sunrise/sunset, and the chart supplement — all offline-ready. WEATHER Local Weather for your home or nearest airport: conditions, a plain-English TAF outlook and the 7-day forecast. Decoded METARs and TAFs, 270+ imagery products cached offline, FAA weather cameras, and FIS-B with an ADS-B receiver. NWS warnings, forecaster discussions and satellite loops arrive live from Tachbase's own GOES-18 satellite dish. TRAFFIC & FLIGHT INSTRUMENTS Connect any GDL90 ADS-B receiver — Stratux, Stratus 3, SkyEcho — for live traffic and weather. A PFD pairs an AHRS attitude indicator with an HSI that tracks your active leg or Direct-To. A customizable data bar adds terrain, obstacle, and traffic alerts with spoken callouts. FLIGHT PLANNING The route finder suggests routes ATC recently assigned — SIDs and STARs load with published legs on the map. Add approaches and airways; check a terrain profile with recommended MEA. Wind-corrected nav log with fuel planning, weight & balance, and PDF export. File, activate, amend, and close flight plans with Leidos Flight Services and official FAA/FSS briefings. Direct-To with holds and track lines. SMART LOGBOOK Log flights with approaches, passengers, and cost-splitting; auto-log with a GPS track; track FAA currency; and generate experience and 8710 reports. Import from ForeFlight or MyFlightbook, export CSV. Sign entries inline or via QR for instructor endorsements. AI APPS & DEVELOPERS Bring Tachbase into Claude or any MCP app, or build on our API: weather, airports, charts and regs — and, only with your approval, read-only access to your logbook, currency and aircraft. tachbase.com/developers PLUS: Home Screen widgets and a live Lock Screen flight activity; an aircraft hangar with weight & balance, POH takeoff/landing distances, and maintenance tracking; normal and emergency checklists; an E6B; an offline FAA library (FAR/AIM, handbooks, ACs); your own POHs and PDFs; iCloud backup; contacts; 8 themes. Tachbase supplements, not replaces, certified avionics and official sources. All data — aeronautical, weather, own-ship position — is for situational awareness only, not for primary or IFR navigation. Per FAA AC 91-78 and AC 120-76, the pilot in command must verify all information against official sources.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. APG Pilot ONE sells 1 in-app purchase, starting at $249.99 per year and Tachbase sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
Tachbase holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: APG Pilot ONE has 19 ratings behind it against 2, so its average is the more settled of the two.
APG Pilot ONE ships an update weekly, Tachbase every 6 days. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
