CompareShots is a tool that helps you compare screenshots and images. Simply select two images, and CompareShots will display them side by side. You can adjust the opacity of the overlay to determine if the images are an exact match. Alternatively, you can touch anywhere on the screen to switch between images. Additionally, if you need to focus on specific details, you can draw directly on the screen. CompareShots is useful when comparing mockups of websites or apps with their actual outcomes. This ensures that the work is pixel-perfect. Furthermore, you can share the results of your work in CompareShots with friends or colleagues.
Stacky

“I need that thing I just copied.” Stacky is a clipboard history and snippet app where copied text quietly stacks up the moment you open it. Everything stays on your device — never sent to our servers. No ads. ◆ Capture • Auto-capture: Copy in another app, open Stacky, and it stacks into your history. • Save Copy: Select text, pick “Save Copy” from the Share menu, and saving and copying happen in one step. • Back Tap: Assign “Save Clip” under Settings > Accessibility > Touch > Back Tap, then double-tap the back of your iPhone to save without opening the app. • Dynamic Island capture meter: Every save stacks the count in the Dynamic Island. Clip contents are never shown — not on the Lock Screen, not in the Island. You see that it was captured, nothing more (optional). ◆ Find & organize • Automatic types: Links, emails, phone numbers, and numbers are tagged automatically — detected without reading the actual contents. • Manual tags: Add your own tags and filter by chip. • Full-text search (Pro): Pull any clip from your whole stack in an instant by keyword. ◆ Templates • Save go-to greetings and email boilerplate, then copy with a single tap. • Auto variables like {date} and {time} (free). • Custom variables like {name} that you fill in when copying (Pro). ◆ Connect (Pro) • iCloud sync: History and templates stay in sync across iPhone and Mac on the same Apple ID. No account, no login. • Mac companion: Text you “Save Copy” on iPhone lands right on your Mac’s clipboard. ◆ Privacy • Clip contents are stored only on this device and in your own iCloud — never sent to our servers. • No ad SDKs, ever. The clipboard holds sensitive things, so we kept the design quiet and clean. • Optionally skip saving password-like text. ◆ Free • 50 clips of history • 10 templates • All capture methods (auto-capture, Save Copy, Back Tap, Dynamic Island) ◆ Stacky Pro • Unlimited history + full-text search • Unlimited templates + custom variables • iCloud sync + Mac companion Pricing: ¥500/month · ¥3,000/year (¥250/mo) · ¥6,000 one-time Monthly and annual plans are auto-renewing subscriptions.
