Kept: Pill Reminder & Tracker

Medical

Kept is a private pill reminder and medication tracker that helps you stay on top of every dose without creating an account or uploading anything to the cloud. Scan the barcode on the box and Kept fills in the medicine name, dosage, and expiry date for you, powered by a fully offline drug database drawn from official health sources in Turkey, the United States, Spain, and France. Build a schedule for medicines you take every day, on specific days, or only as needed, and let smart reminders find you at just the right moment. Miss a dose, and Kept quietly follows up instead of letting it slip by. Quiet hours protect your sleep, while the medications that matter most can still sound a stronger alert. A friendly history shows your adherence streaks and what's coming up next, and you can share a clean PDF with your doctor in a single tap. Track your stock so you always know when to refill, and manage medicines for your whole family, parents, a partner, or children, from one place. Home screen and lock screen widgets show today's progress and your next dose at a glance. Every medicine and health detail stays only on your device. Kept never sends your data to a server.

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.

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.

Readlight: Night Reading Light

Utilities

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.
