Construction Log Offline
RostaK
Construction Logbook Offline helps tradespeople, small contractors and construction companies keep a clear site diary directly on their phone.
The app is designed for fast daily records from the construction site: completed work, workers, shifts, weather, materials, photos, signatures and PDF export. It works without registration, without a user account and without required synchronization.
You can now use the AI assistant. It can prepare a draft construction logbook retrospectively from ordinary notes, dictated text, OCR text, delivery notes or photo metadata. Your notes do not need to be perfectly structured day by day – AI helps organize them, draft daily entries and fill selected details.
AI output is always a draft. You review it, edit it and only then save it to the logbook.
Main features:
• daily construction records,
• retrospective AI draft from notes,
• AI completion of an existing logbook,
• AI help when editing a daily entry,
• voice dictation,
• OCR from camera and gallery,
• photo documentation with captions,
• signatures directly on the phone,
• PDF export of the construction logbook,
• internal notes excluded from PDF,
• full-text search in logbooks,
• offline-first use without account or registration.
For one AI import, we recommend a maximum of 20 working days. Longer periods can be split into several parts and added gradually.
AI credits:
• 1 AI credit = 1 successful AI draft processing,
• Support development / PRO adds initial AI credits,
• additional AI credits can be purchased in the app,
• a credit is not deducted if the draft cannot be created.
The app is useful for:
• self-employed tradespeople,
• construction trades,
• small construction companies,
• technical supervisors,
• renovations, installations and smaller construction projects.
Core features work offline. AI features require an internet connection and available AI credits. Always review AI output before saving, especially dates, weekends, holidays, workers, materials, OCR text and work periods.
