Answers now arrive faster in weak signal, and the last procedures you used stay available with no reception at all. ### 1.0.5 — 2026-08-06 Apple Watch companion improvements: • Voice sessions run hands-free, so you can keep both hands on the job. • A safety timer for live-wire and confined-space work. • Cached first-fix answers keep working when you lose signal in a crawlspace or on a roof. Plus stability fixes throughout. ### 1.0.4 — 2026-08-06 One conversation from problem to fixed: • Type, snap a photo, talk, or jump to a live voice call — all in one thread, without losing your place. • Scan a nameplate to identify the exact unit and its verified repair tree, then diagnose. • Reference now comes to you: the part, the procedure, and a live superheat/subcool calculator appear right in the conversation. • Cleaner navigation — start a fix in one tap. ### 1.0.3 — 2026-07-14 • Claude Fable 5 now powers diagnostics and vision — sharper answers and a much better read on what your camera is showing. • Hands-free on Apple Watch — neural voice, complete spoken answers, and one-tap send from the wrist. • A back button on every screen.
