There are things you want to write down without worrying about what anyone else might think. Sometimes you want a personal album of memories that isn't meant to be shared with anyone. MemoMa is an app for people like you. MemoMa displays only your own notes and photos. There are no ads or recommendation algorithms, so you can enjoy a completely private space, free from social media. It's perfect for keeping a journal of everyday life that doesn't need to be shared, or for recording personal health information that you'd rather keep private. Of course, you can also relive your favorite trips through photos and add notes to your pictures so they're easier to find later. Your notes are available across your iPhone, iPad, and Mac, so you can pick up where you left off on any of your devices. If you enable iCloud Photos, your photos will be available across your devices as well. Simply open MemoMa and tap the "+" button to create a note. Your notes appear in chronological order on each day's timeline. Photos are not imported into MemoMa. Instead, the app displays the photos you've taken with the Camera app. You can choose to display only specific albums or hide photos you don't want to see. Long-press a photo and select "Add Note" to make it searchable by the note's contents. You can search using multiple keywords with either "Match All" or "Match Any" options. If you set a date and time when creating a note, it can also be saved as a calendar event. In Edit mode, you can duplicate notes and events, change their dates, or delete multiple items at once. You can take notes while viewing your photos, keep the notes, and later delete photos you no longer need with a simple long press. Please note: MemoMa cannot protect the privacy of items added to public calendars or shared photo albums. Calendar data itself is not encrypted, so other apps that have access to the same calendar may also be able to view it. To help protect your privacy, MemoMa includes a Private Mode that prevents others from casually viewing your information. For more information, please read the User Guide from the Settings screen in the app.

**Empower yourself to find the TRUE best deal.** Ever stood in a supermarket aisle, staring at products with different quantities, wondering which one is actually cheaper? "2,343 yen for 320 sheets x 24 packs" versus "2,726 yen for 400 sheets x 5 boxes x 2 sets" – can you calculate which is better on the spot? When stores display products with varying pack sizes and bundle configurations, intuition alone won't reveal the true best value. "Unit Price Comparator" instantly solves this problem, becoming your essential tool for smart shopping. **■ Key Features** ◆ Precise Comparison Across Any Unit Whether it's "sheets" for tissues, "meters" for toilet paper, or "grams" and "ml" for food items – set the optimal common unit for each product category. No matter how complex the packaging, the app calculates the cost per sheet, per gram, or per meter down to the decimal point. ◆ Smart Input System Our three-tier input method ("Capacity per item × Quantity per pack × Number of sets") makes it easy to register even the most complex products like "320 sheets per box, 24 boxes per case." Total quantity is auto-calculated, preventing input errors. ◆ Auto-Fetch from URLs Simply paste a URL from Amazon or other e-commerce sites, and the app automatically extracts the product name, price, and image. Comparing online and in-store prices has never been easier. The app even parses product titles to extract information like "24 cans" or "350ml," dramatically reducing manual input. ◆ Price Tag Photo Storage Snap photos of in-store price tags and save them with your products. Fine-tune the display position so the price and product name are clearly visible. Perfect for checking "How much was this last time?" later. ◆ One-Tap Tax Calculation Don't worry about tax-exclusive prices. Tap the +8% or +10% tax rate button to instantly convert to tax-inclusive prices. Tax rates can be customized in settings. ◆ Instant Best Deal Identification Sort products in the same category by unit price, and the cheapest item is automatically marked with a "Cheapest" badge. No hesitation – grab the best value option with confidence. ◆ Multilingual Support Supports Japanese and English. Automatically switches based on system settings, with manual language selection available in-app. **■ Perfect For** • Shoppers who struggle to determine which pack offers the best value at supermarkets and drugstores • Anyone who wants to accurately compare online and in-store prices • Smart buyers of complex bundle products (tissues, toilet paper, beverages, etc.) • Budget-conscious individuals serious about household savings • Those who want to manage shopping lists with photos **■ Simple to Use** 1. Create categories (e.g., Tissues, Toilet Paper, Beer) 2. Add products (snap price tags in-store or fetch info from URLs) 3. Enter "Capacity per item," "Quantity per pack," and "Number of sets" 4. Unit price is auto-calculated, and the best deal is instantly clear! **■ Privacy & Data Management** All data is stored locally on your device. Nothing is sent to external servers.
