Frog Construction Toolkit

One app for the jobsite—from the first measurement through material takeoffs, project records, and the final checklist. Built around the work, not around a maze of calculators.

← Back to all apps

Start where the work is.

The goal is straightforward: a contractor should be able to show up at a job with this one app and work through the project in the order the job actually happens. Open a job, choose the part you are working on, enter the measurements, calculate what is needed, and keep the results with the work. No need to be a tech expert to find the next step.

For the walls that didn't read the blueprints.

A new build can follow the drawing. A remodel may have a wall that leans, a corner that isn't square, or measurements that disagree with the original plan. Frog Construction Toolkit is being developed with both jobs in mind: standard construction and the strange, stubborn details that show up in real buildings.

Installing an APK on Android

  1. Once available, download the APK on your Android phone.

Website APKs do not receive Google Play automatic updates. Updating an installed app requires a compatible Android package and signing certificate.

This page checks whether a public APK exists; it does not independently verify the file's safety or signing certificate.

Designed for use—not decoration.

Easy-to-follow steps, clear labels, and useful results matter more than flashy screens. This is a work in progress, and the tools described here are the development direction—not a claim that every feature is finished or validated. Check the download section for current public APK availability.

Important planning note: Material estimates and structural or code-related references are informational only. Verify site conditions, applicable local code, manufacturer requirements, and any engineered design with the appropriate qualified professional or authority.

Free. Simple. Respectful.

No ads, subscriptions, paywalls, or paid feature unlocks. Optional support will never change what you can use. The plan is to build a practical tool you can trust—not another monthly bill.
