Are you going to build or remodel? Have you estimated the expenses? When the subject is construction the costs of the work almost always extrapolate the budgets. The calculation of building material such as material needed to make a wall, a floor, tile, build a staircase, etc. are not always accurate and errors in the purchase of the material generate waste and can increase the cost of a work or renovation. Have you considered accurately managing the inputs of your work? Well this reality is already possible through ConstruCalc! You can estimate more accurately the building materials and their respective quantities that will be used in your work, so you avoid waste, improve your budget and reduce the cost of the work. This application assists you in calculating the materials needed to: - Concrete (Amount of concrete, volume of gravel, volume of cement, volume of sand, volume of water) - Wall (brick quantity, block quantity, amount of solid brick, mortar volume of settlement, volume of sand, calculation of plaster), besides the possibility to select the position, standing brick or lying brick - Thick Floor (Volume of cement, volume of sand, volume of gravel) - Complete Floor (Volume of cement, amount of floor, amount of ceramic or porcelain tile, subfloor of regularization, volume of mortar, volume of grout, baseboard) - Laminate Flooring (Quantity of laminate flooring, baseboard, PVA mass for leveling and floor covering) - Vinyl Floor (Quantity of vinyl floor, baseboard, PVA mass for leveling and glue) - Liquid Porcelain (Volume of epoxy resin, hardener, sealer and pigment for Primer and Finishing Options: 3D or ordinary liquid porcelain) - Interlocked floor (Pavi's, Pisogram S, 16 Faces, Rectangle, Hex or Block, Racket, Double T and 3 Tips) - Tile (Tile quantity, grout volume, settling mortar volume) - Pastilles (Quantity of ceramic or porcelain paste, volume of grout, volume of mortar) - Ladder (Number of steps and volume of concrete.) Ladder options: Straight staircase, straight staircase with landing, L-shaped staircase and U-shaped staircase) - Plaster (Amount of gypsum) - Plaster (Quantity of material required for the internal and external lining, including slab, plaster and plaster) - Paint (quantity or volume of paint, volume of sealer, volume of varnish, quantity of mass, quantity of coats) - PVC (Quantity of PVC liner, PVC modular board and PVC partition) - Tile (Quantity of ceramic, cement, asbestos or metallic tiles and number of ridges) - Useful Tables: NBR6118, NBR6120 and practical table with concrete traces for use in works (Caldas Branco) - Foundation, Beam, Pillar and Floor. - Ceramic slab and EPS slab. - Stairs, Hardware and Wood. Suitable for all who work with civil construction, such as bricklayer, painter, gossip, civil engineer or even who is lay in the subject. ConstruCalc is the solution you need for your work.

Verdict
The clearest difference is review sentiment: ConstruCalc at 77% against InstElectric's 0%. InstElectric's advantage is rating (4.3 vs 3.4) and iOS requirement (8.0 vs 15.6). On price, ratings volume, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
InstElectric holds the better App Store score, 4.3 against 3.4. Both are backed by a comparable volume of ratings — 7 and 3 respectively. Written reviews complicate that: 77% of ConstruCalc's written reviews are positive against 0% of InstElectric's, so the app with the better star average is not the one people write more warmly about.
ConstruCalc ships an update every 5 weeks, InstElectric monthly. The most recent releases landed on October 24, 2026 and September 19, 2026 respectively.
