Our apps

We build and ship our own digital products—from first idea to the App Store. Here are the apps we are working on right now.

Brushlings

iOS · AR toothbrushing for kids · Ages 3+

Problem

Getting kids to brush properly—and for the full two minutes—often turns into a daily battle. Most approaches add pressure instead of making toothbrushing something children actually look forward to.

Solution

Brushlings places cute AR masks on your child's face and guides them playfully through two real brushing minutes. Brush morning and night for three days to reveal a new collectible Brushling—ears, eyes, and mask parts appear step by step while they brush. Collect up to 60 characters. No ads, no trackers; the camera image never leaves the device.

Juno

iOS & Android · Memory books for families

Problem

Parents capture thousands of photos and videos, but childhood milestones slip away—scattered across phones, never organized into something lasting.

Solution

Juno helps families capture memories with text, photos, and video—then turns selected entries into beautifully printed memory books in minutes. GDPR-compliant, made in Germany.

Tallo

iOS & Android · Family pocket money

Problem

Pocket money is easy to forget, hard to track, and tough for kids to understand where their money goes—or how saving toward a goal actually works.

Solution

Tallo automates allowances, helps kids save for goals, and gives parents a simple overview. Free, no ads, servers in Germany, data encrypted.

Boomer Cal

iPhone & iPad · Year-at-a-glance calendar

Problem

Calendar apps bury the big picture in day views and menus. Planning a year—or spotting a free weekend—takes dozens of taps.

Solution

Boomer Cal shows all twelve months on one screen, synced with Apple Calendar. Smart pins, custom colors, dark mode—and a one-time purchase, no subscription. Your data stays on your device.

Tidow

macOS · Downloads organizer

Problem

Most Mac users' Downloads folders are chaos—PDFs, screenshots, installers, duplicates—until someone wipes the whole thing and loses something important.

Solution

Tidow automatically sorts and cleans your Downloads with smart, on-device rules. Source-aware routing, Apple Intelligence for document content, and scheduled cleanup—100% local and private.

Sunlight Sim

iOS · Natural light simulation

Problem

Apartments can look bright at noon and dark by afternoon. Renters and buyers often only discover bad light after signing a lease.

Solution

Sunlight Sim previews how sunlight fills a room across the day and seasons—from one photo, any address, with nearby building shade. Save locations, compare rooms, and export PDF summaries.

Flavor Friends

iOS · Cozy puzzle game · Free to play

Problem

Mobile puzzles often pile on timers, ads, and pressure—turning a quick break into something stressful instead of genuinely fun.

Solution

Flavor Friends is a cozy scoop-sorting puzzle: slide flavours between cones until every scoop finds its family, then watch them come to life as adorable ice cream characters. 35 hand-crafted levels across five dreamy worlds, three-star challenges, no timers—free to play, made to make you smile.
