Apple made waves with its latest announcements at the Worldwide Developer Conference, introducing a range of new features for its devices. However, many of these features were already available through third-party apps, leading to the term "Sherlocking" - when Apple introduces a feature that mirrors an existing third-party app. The new Apple password manager will compete with apps like 1Password and LastPass, while call recording and transcription will challenge TapeACall and Truecaller. Voice transcription in apps like Notes will rival Otter and AudioPen. Mac users can now mirror their iPhones without Bezel, and window tiling will be included in MacOS Sequoia, potentially affecting apps like Magnet and Rectangle. Custom emojis and maps will also see Apple challenging apps like Newji and Alltrails. Apple's move into these spaces may impact third-party apps, but some may continue to thrive by offering unique features or enterprise solutions. Apple's Writing Tools suite is using AI to provide a range of features, potentially impacting apps that offer similar services like Grammarly.
