Deep Dive Drill vs MotorSitter

Identify Minerals in the Field Walk through a structured identification workflow based on the Mohs hardness scale and standard mineralogical criteria. No equipment beyond what you carry. No guesswork. No internet connection. Build Your Personal Collection Save identified specimens with photos, location notes, collection date, and custom descriptions. Filter and sort your collection by mineral class, match quality, or date. Every specimen stays on your device — no account needed. Browse the Reference Database Explore a comprehensive mineral database with detailed entries covering chemical formula, crystal system, specific gravity, associated minerals, and occurrence contexts. Filter by luster, color, hardness, class, and more. Track Your Session History Review every identification session with a full recap of your answers and top candidates. See your monthly activity, overall confidence rate, and your most frequently encountered minerals.

MotorSitter turns your odometer into a clear maintenance dashboard. Add mileage readings and see how much distance remains before engine oil, filters, brake pads, tires, and custom service items are due. Once enough readings are available, MotorSitter can estimate due dates from your recent driving pace. Mileage-based and time-based intervals can be edited for each vehicle, so items that age by months are tracked even when the car is driven less. Keep service jobs, fuel stops, documents, and costs organized for any number of cars. Full-tank fuel entries can be used to calculate consumption, while partial top-ups carry forward until the next full-tank reading. The Log keeps your history together, Costs collects priced entries, and Garage lets you manage every vehicle, service plan, custom job, and document from one place.
