Runsheet
Paid, one-time · ₩4,400 / $2.99
A session runner for presenters, instructors, and workshop hosts. Plan your agenda as timed segments, then run it on stage: a large timer for the current segment, a preview of what's next, and a clear warning when you're over time. Works fully offline.
Cadence
Free
A minimal daily routine tracker. Build the template of your ideal day once — items with optional times — then follow it every day with simple check-offs and streaks. Local storage only.
Gridline
Free with a banner ad · Pro $3.99 one-time
A grid and value reference for painters and illustrators. Lay a grid over a reference photo, check it in grayscale or a few flat value steps, and crop to your canvas with real cell sizes. Photos stay on your device. Pro removes the ad and unlocks value steps and canvas crop.
Crumb
Free with a banner ad · Pro $3.99 one-time
A formula calculator for sourdough and home bakers. Type percentages or grams and the other updates, with levain and wet add-ins counted in hydration. Scale any batch and get the water temperature for your target dough temperature. Pro removes the ad and adds unlimited formulas.
