Pebble Ships 23K Time 2 Watches, Doubles Battery Life, Pushes Open-Source SDK

Pebble’s revived hardware effort (now under Core Devices) is closing out its Pebble Time 2 pre-order backlog, having built more than 23,000 units since mass production began in late March. That covers over 80% of orders, with the last color variants shipping by the end of July — after which the company expects to hold open stock for the first time. Alongside the hardware milestone, the four-person software team has landed substantial PebbleOS gains, most notably power optimizations that lifted the Pebble 2 Duo’s median battery life from 17 to over 30 days, with the Time 2 currently near 21 days.

The update leans heavily on the platform’s open-source, developer-driven ethos. New SDK features built with the Moddable team include touch-screen, speaker, and RGB backlight APIs, native JavaScript apps (Alloy) with FFI to run C code and an integrated JS debugger — and the community has already produced 2,120 apps and watchfaces for the new models. Contributors have added Apple HealthKit and Google health sync, notification filtering, and language packs, with HRV, SpO2, and BLE heart-rate exposure on the way. The companion Index 01 feature set (task syncing to Obsidian, Google Tasks, and iOS Reminders, plus webhooks, MCP support, and optional user-held-key encryption for cloud backup) is now live in the mobile app.

On the harder problems, Pebble is untangling its legacy “reverse PPoGATT” Bluetooth setup — a first-era workaround for iOS IPC limits that now blocks adoption of Apple’s AccessorySetupKit. Migrating requires updating recovery firmware across every fielded watch before notification replies (EU only) can ship, a fix the company frames as a long-running saga. It also candidly lists three unresolved Time 2 software bugs — inaccurate step/sleep tracking, an accelerometer that intermittently stops, and flaky touch input — with no ETA, plus acknowledged hardware defects covered by support.
