THE DAILY CONTROL QUESTIONS
Know what happened, what changed, and what needs your decision.
Rangka is organised around the questions a project manager asks every afternoon—not around another set of forms for the site team.01
What actually happened on site today?
Messages, voice notes, and photographs are grouped under the project and date so the day can be reviewed as one evidence trail.

Which activity and progress does it affect?
Rangka prepares the work completed, progress, issue, and likely schedule activity. The PM confirms or corrects the interpretation.

HOW RANGKA WORKS
The field stays simple. Project control gets structured.
One controlled handoff from the message your supervisor already sends to the record your project team can rely on.- 01
Capture
The supervisor sends an ordinary Telegram message, photograph, or voice note.
- 02
Organise
Rangka groups the source evidence under the correct project and work date.
- 03
Review
The PM checks the interpretation, task match, progress, report wording, and any schedule effect.
- 04
Approve
Only the PM decides what updates the task, report draft, approved schedule, or project record.
ONE PROJECT STATE
Field evidence, programme, and report stay connected.
FIELD UPDATES
Keep site reporting where it already happens.
Telegram remains the field interface. Rangka preserves the original text, voice, and photographs, then makes the day searchable by project and date.

DAILY REPORTS
Issue the report only when the record is ready.
Reviewed field updates prepare the daily-report draft. The PM can edit the wording, include or exclude contributions, attach missing photographs, and approve the final report.

HUMAN APPROVAL IS THE SYSTEM
AI prepares. The PM approves.
Rangka can interpret a field update and calculate a proposed schedule effect. It cannot decide that an uncertain statement is contractual fact. The project manager sees the source, changes the prepared fields where necessary, and chooses the outcome.
- Source evidence visible
- AI-prepared state labelled
- PM edits before approval
- Rejected items remain auditable

COMMON QUESTIONS
Before you connect the first project.
01Do supervisors need to install another app?+
No. The field workflow uses Telegram. Project managers use the Rangka web workspace for review, scheduling, reports, and records.
02Does Rangka approve reports automatically?+
No. Daily reports remain drafts until an authorised project manager approves them.
03Can AI change the project schedule by itself?+
No. A detected delay can produce a proposed impact, but nothing changes until the PM explicitly confirms the effect and approves the update.
04What happens to the original evidence?+
The source message, voice note, transcript, and photographs remain connected to the field update and approved task history. Messages are hidden, not deleted.
05Is WhatsApp supported for field reporting?+
Not currently. Telegram is the supported field-ingestion channel.
06How does the Free plan work?+
The Free plan does not expire and includes one active project, three workspace users, field contributors, and limited monthly AI and PDF usage. No credit card is required.
07Are paid plans charged per user?+
No. Core and Business are priced per active-project slot. Field contributors do not consume workspace seats.
