Fruitstand vs WärmePilot

Fruitstand is the one place to store your entire Apple collection on all the Apple products you love. Store info about Mac, iPhone, iPad, Apple Watch, AirPods, Apple TV, iPod, HomePod, Apple Vision, and accessories. YOUR COLLECTION: Add info about each of your Apple products to Fruitstand. When you add a product to Fruitstand, you can add info about that product's specifications, color, condition, warranty status, activation lock status (if applicable), and serial number. You can also add additional comments and custom attributes. Fruitstand will automatically organize your collection by product type and model, with additional sorting options. Edit your collection at any time, and hide products from the main view. POWERFUL SEARCH: Search your entire collection with ease. Search with keywords and/or filters to find just the products you want. Sort search results by product value or year acquired. CUSTOM ATTRIBUTES: Add custom attributes to any of your products. These attributes can have a name, value, and optionally a color, font type, and one of over 6,000 SF Symbols associated with them. Once a custom attribute is added to one product, it will be available for use on all your products. Custom attributes are also searchable across the app. SYNC ACROSS ALL YOUR DEVICES: Fruitstand will automatically sync your collection across all your devices with iCloud. Any additions, edits, or deletions to your collection will be reflected on the other devices connected to your Apple Account.

Fruitstand provides you the option to specify your level of security; you may choose to enable biometrics when launching or resuming the app, deleting products, adding/loading products, and/or editing products. WIDGETS: See your collection at a glance with widgets. The small widgets show your total collection size or total collection value. Medium widgets break down your collection size and collection value by product type. The large widget will show even more statistics about your collection value.

WärmePilot is your digital assistant for heat load calculations — right on your iPhone or iPad. Whether you own a house, rent an apartment, or manage a multi-family building: find out how much heating power your building really needs, which heat pump fits best, and how renovation measures affect your energy costs. LIDAR ROOM SCANNING Use your device's LiDAR sensor to measure rooms in seconds. WärmePilot detects walls, windows, and doors automatically and stores the scan as a rotatable 3D model. No LiDAR? Manual entry works too. HEAT LOAD CALCULATION (SIMPLIFIED METHOD BASED ON DIN EN 12831) Enter postcode and construction era — the design outdoor temperature and U-values are determined automatically. Rooms and elements can be edited any time. FLOW TEMPERATURE PER ROOM (NEW) Capture the installed radiators per room and see the required flow temperature for each (DIN EN 442). Traffic-light rating shows which radiators should be upgraded for heat-pump operation. HEATING CURVE (NEW) Interactive curve with slope and level. Includes recommendations for underfloor heating (0.2–0.6), modern radiators (0.8–1.6) and legacy radiators (1.6–2.0). SEASONAL PERFORMANCE — SCOP (NEW) True seasonal coefficient of performance using DWD test reference year data for 15 German climate regions, linear COP interpolation from EN 14511 support points, monthly heating-degree-day weighting. Efficiency class A++ to B. HOT WATER & BUFFER TANK (NEW) Demand calculation per DVGW W 551 / VDI 4708 with legionella protection. Buffer tank recommendation with type selection (hydraulic separator, parallel, serial, inline). CONSUMPTION RECONCILIATION (NEW) Compares measured prior-year consumption against the calculated heat load. Energy class A+ to G, plausibility traffic light, concrete warnings for deviations. Fuel-to-kWh conversion (gas m³, oil L, pellets kg). NOISE CHECK PER TA LÄRM (NEW) Validates the outdoor unit against TA Lärm noise limits. All 7 German zone types, reflection corrections, silent mode, minimum-distance calculation. ENERGY COST COMPARISON Compare annual costs of your current heating system (gas, oil, electric) versus a heat pump. CO₂ savings included. HEAT PUMP RECOMMENDATION (290+ MODELS) Curated bestseller database with 54 models from Germany's top brands plus 230+ EU-certified models — separated into monoblock and split. R290 refrigerant highlighted. Top 20 comparison list. SUBSIDY CALCULATOR (BEG/BAFA/KfW) Base subsidy, climate-speed bonus, efficiency bonus R290, iSFP bonus, income bonus — capped at 70%. BIVALENCE POINT & AMORTIZATION Bivalence point and cumulative cost over 25 years. Interactive sliders for price escalation and subsidy. PRICING 1 building included (€14.99) — full depth: flow temp, heating curve, SCOP, hot water, consumption reconciliation, noise check, all calculations, standard PDF.
