Clever Dash Set v1.3 contains ten dedicated calculation modules, each purpose-built for a specific construction material or system. The brick and mortar calculator accepts wall dimensions in metres, wall thickness (half-brick, single-brick, or double-brick), and standard or custom brick sizes — then outputs exact unit counts and mortar volume. The concrete mix module maps your pour volume against industry-standard ratios to return cement bags, sand weight in kilograms, gravel volume in cubic metres, and water in litres simultaneously.
The Projects module stores multiple renovation jobs in parallel. Each project holds a task checklist, a live budget dial showing spend versus total allocation (for example 500.00 USD against a 4,000.00 USD cap), and a colour-coded room category. Progress rings update as tasks are ticked off, giving a percentage view of completion state. All project data is stored on-device — no account, no sync, no data charge.
The converter handles length, area, volume, and weight between metric and imperial, with construction-specific units like board-feet and cubic yards included. Quick-reference tiles display the four most common conversion factors (1 ft = 0.30 m, 1 m = 3.28 ft, etc.) for fast field checks without typing. The Mix Timers section carries preset countdowns for concrete initial set, mortar open time, and grout cure — each with background notifications that fire even when the phone screen is off.
Ten dedicated modules cover Bricks and Mortar, Concrete Mix, Paint Coverage, Tiles and Grout, Flooring, Drywall, Roofing, Wallpaper, Electrical, and Building Blocks. Each module outputs material quantities specific to the job — for example the Drywall calculator returns sheet count, screw count, profile lengths, and joint compound volume all from a single room measurement.
Create and manage multiple renovation projects simultaneously. Each project stores a named task checklist with tick-off progress, a live budget tracker showing current spend against total allocation in US dollars, and a room category with custom colour coding. Progress percentage updates in real time as tasks are completed.
Instant conversion across length, area, volume, and weight between metric and imperial systems. The interface shows quick-reference conversion tiles — 1 ft = 0.30 m, 1 m = 3.28 ft, 1 m = 1.09 yd — for checking common ratios without entering a value. Construction-specific units including board-feet and cubic yards are included alongside standard SI and imperial sets.
Preset material timers for Concrete Initial Set, mortar open time, and grout cure are included out of the box. Custom timers can be created for any material with user-defined duration. Background notifications deliver an alert when the countdown ends, even when Clever Dash Set is not in the foreground — critical for staying on schedule without babysitting the screen.
Every calculation in Clever Dash Set can be saved to the project record or shared directly via iOS share sheet. The Wallpaper Calculator, for example, outputs rolls needed and adhesive weight, then offers Save and Share buttons to drop results into a notes app, message, or email — keeping material lists accurate from estimate through to purchase.
Clever Dash Set requires no internet connection to calculate, convert, track projects, or run timers. All computation happens on-device using local data. This matters on active construction sites where mobile signal is unreliable — concrete mix ratios and brick counts are available the moment you open the app regardless of connectivity status.
Clever Dash Set is built and maintained by Mohamed Rehab, an independent iOS developer. Current release is version 1.3, available free of charge on the App Store for iOS 16 and later. The app is optimised for iPad and receives active maintenance — version 1.3 resolved estimate and calculation bugs within 17 hours of report. Copyright © 2026.
