This week on AppleInsider: Apple's blockbuster Q2, 'tattoo-gate,' Apple Watch review, more

Apple reaps $13.6 billion in second-quarter results

On Monday Apple announced $58 billion in revenue and $13.6 billion in net profits for the March-quarter, driven mostly by sales of 61.17 million iPhones. iPad sales were down, though, meaning Macs actually eclipsed the tablet in terms of revenue.

Apple simulatenously added another $50 billion to its capital return program, with the goal of reaching $200 billion in dividends and stock buybacks by March 2017. Some other announcements included the goal of bringing the Apple Watch to more countries in June, and Best Buy launching support for Apple Pay despite being allied with rival mobile payment service MCX.

'Tattoo-gate' finds Apple Watch fooled by ink

Tuesday saw complaints from Watch owners who reported that their tattoos were disrupting operation of the device's optical sensors, causing problems with notifications, heart rate tracking, and even unlocking. Apple confirmed the problem on a support page, noting that the "ink, pattern, and saturation of some tattoos" can block light.

Some of the issues can be solved by disabling wrist detection, but this also disables Apple Pay, and forces users to track their heart rate with a separate Bluetooth accessory.

Apple Watch review: Beautiful but rough

Our review found that the Watch has new and intuitive interface technologies, and great hardware design, including both the device itself and its many band options. The Watch implementation of Apple Pay was described as convenient and futuristic.

At the same time the wearable scored only 3.5 out of 5 stars, owing to slow third-party apps, an awkward companion app on the iPhone, and troubles with Siri and Passbook. The device also lacks any support for third-party watchfaces, despite Apple's nominal focus on personalization.

Watch rollout slowed by defective Taptic Engine parts

The Wall Street Journal reported on Tuesday that low shipments of the Watch might be traceable to faulty Taptic Engine motors built by AAC Technologies. Though none of the parts are believed to have reached the public, the manufacturing speed bump allegedly forced Apple to shift most Taptic Engine production to its second supplier, Nidec.

Apple has reportedly told various Watch parts suppliers to slow production until June to account for the slowdown. It remains to be seen how that will affect Apple's hopes of launching the product in more countries next month, or plans to offer walk-in purchases at Apple Stores.

Developers get early access to App Analytics

For developers, Apple began rolling out a beta of App Analytics. The tool lets people track performance metrics for App Store titles without having to turn to third-party services, which may charge a fee and/or use indirect data sources.

Access to the beta is being granted on a first-come-first-served basis. Developers can apply through iTunes Connect.
