It focuses on simplicity, ensuring you have a clear overview of your financial obligations without being overwhelmed by complicated banking apps or messy spreadsheets.

Readlight – Screen Light

Lifestyle

Readlight turns your iPhone into a dedicated reading light — warm, adjustable, and easy on the eyes. Designed specifically for reading in bed or in the dark, it gives you full control over brightness, color temperature, and light distribution so you can find the perfect setting for any environment. Unlike harsh white screens, Readlight offers warm and cool light modes that reduce eye strain during long reading sessions. Its full-screen illumination ensures even, glare-free light whether you're reading a physical book, a magazine, or just winding down before sleep. The built-in sleep timer is a standout feature: set it once and let the app automatically dim and lock the screen — so you never wake up to a bright display after dozing off. Combined with the always-on display mode, Readlight is the closest thing to a real reading lamp on your phone. If you're a night owl who loves to read without disturbing a sleeping partner, or someone who simply wants better control over their screen as a light source, Readlight is built exactly for that.

Currency Converter: Offline

Finance

Exrate is a fast, no-fuss currency converter built for people who need reliable exchange rates — online or offline. Whether you're traveling abroad, shopping internationally, or tracking crypto assets, Exrate gives you instant access to conversion rates for over 1,000 currencies, cryptocurrencies, gold, and silver. What sets Exrate apart from other converter apps is its offline mode. Exchange rate data is cached locally, meaning you can keep converting currencies even without a Wi-Fi or mobile data connection — a must-have when traveling to areas with unreliable internet. Beyond travel, Exrate is useful for freelancers invoicing international clients, investors tracking multi-currency portfolios, and anyone who deals with foreign money regularly. The interface stays clean and minimal, so you can get a conversion in seconds without digging through menus. With support for over 1,000 currency pairs and a built-in economic calendar for staying informed about market-moving events, Exrate covers far more ground than the typical converter app.

T1: Undervalued Crypto Finder

Finance

T1 is a crypto research tool built around a single, powerful idea: the further a coin is from its all-time high, the more potential upside it may carry. Instead of drowning you in charts and raw percentages, T1 analyzes the ATH distance of 1,000+ cryptocurrencies and translates that data into clear, actionable labels — Worth Buying, Watch, or Overheated. This approach helps traders quickly cut through the noise and focus on opportunities that are actually worth their attention. If a coin is trading near its all-time high, T1 flags it as Overheated. If it has pulled back significantly, it may show up as Worth Buying. The app does the screening so you don't have to. Premium users get an even more focused experience: a filtered view that shows only "Worth Buying" coins, customizable alerts when a coin enters a buy zone, and an ad-free interface optimized for quick decision-making. T1 won't tell you what to buy — but it will help you see the market more clearly. It's built for opportunistic traders who value speed, simplicity, and better-informed decisions over speculation.

GuestList – Event Planner

Productivity

GuestList is a dedicated guest management app built to take the chaos out of wedding planning and event organizing. Instead of juggling spreadsheets, paper lists, and scattered messages, GuestList gives you a single place to track every guest — from initial invite to final RSVP. The app is designed with simplicity in mind: create an event, add your guests, organize them into custom groups (family, friends, colleagues), and track their attendance status in real time. You always know exactly who's coming, who hasn't responded, and who you're still waiting on. GuestList also handles the practical side of event planning. Export your complete guest list as a PDF or Excel file for printing or sharing with a venue. Manage multiple events simultaneously — perfect if you're coordinating a wedding alongside a rehearsal dinner or a bridal shower. Whether you're planning an intimate ceremony of 30 or a large wedding with 300 guests, GuestList scales to your needs. It replaces the friction of traditional planning methods with a calm, organized workflow that keeps you focused on celebrating — not administrating.

Orer: App Update Tracker

Developer Tools

Orer is the update tracking and management system built for indie developers and app marketers who need to stay active, competitive, and visible on the App Store. It monitors App Store updates in real time and notifies you the moment a new version is released — for your own apps or your competitors'. What makes Orer unique is its stagnation alert system. You define expected update frequencies per app — 14 days, 30 days, 90 days, or any custom interval — and Orer alerts you when an app misses its update window. App Store algorithms favor consistency, and Orer helps you enforce it before your rankings slip. The competitor monitoring feature is equally powerful. Track competitors in your niche, monitor their update dates and version changes, read their release notes over time, and spot ranking opportunities when rivals go silent. Knowing when not to ship is just as strategic as knowing when to ship. Everything lives in one clean dashboard: update notifications, version history, app portfolio view, relationship tags (your apps, competitors, general interest), built-in task management for planning features and tracking bugs, review monitoring across 150+ App Store regions, and detailed market metadata. Orer is the cockpit for developers who ship seriously.
