What to compare

• Price model: a subscription charges every month or year for as long as you use the app, a one-time purchase charges once, and a free app with purchases inside charges for the parts you add.
• Fractions: the finest fraction it shows (1/16, 1/32 or 1/64), and whether it tells you when a result is rounded.
• Entry and history: whether you can see what you entered and change an earlier line.
• Solvers: stairs, rafters, board feet, concrete, circles and arcs, and whether they are in the price or sold separately.
• Metric: millimeters, centimeters and meters in the same calculation.
• Offline: whether it runs in a basement or a crawl space with no signal.
• Sharing: whether you can send a result or a sheet to a client or a supplier.
