Who It Helps
- People currently on GLP-1 related treatment plans
- Users who need stable reminders and complete historical logs
- Users who want long-term tracking between weight and execution quality
iOS App for GLP-1 Routine
Turn GLP-1 treatment execution
from memory-based to system-based.
LightNeedle is built for execution management. Reminders, records, trends, and review stay on one continuous timeline, reducing missed actions while preserving traceable data.
Weekly / daily / twice-daily / meal-time protocols
Notification + persistent reminder backup
Local-first storage with Apple Health sync and CSV export
LightNeedle is an execution management tool and does not replace professional medical advice.
Product Positioning
Designed for long-term treatment execution, not one-off check-ins.
It addresses three core issues: missed actions, incomplete records, and low-quality review. Every execution event becomes trackable and reviewable.
Core Value
- Automatically reschedules reminders when treatment rhythm changes
- Supports backfill and timeline continuity to reduce data gaps
- Maintains weekly review quality with trend pages and execution cards
Product Boundary
- Does not provide diagnosis, prescriptions, or medical conclusions
- Dose adjustments and treatment decisions should follow physician guidance
- Seek professional medical support immediately for severe discomfort
Core Capabilities
Focused feature set built around real execution workflows.
Reminder Scheduling Engine
Supports notifications, persistent reminders, and dual-mode backup with automatic rescheduling after plan edits.
In-treatment Onboarding
Start from an ongoing treatment stage, backfill by week/day sequence, and calculate the next reminder automatically.
Quick Logging Entry
Log injection/intake and weight from the home screen with optional dose, site, notes, and photo attachments.
Unified Timeline
Injection, intake, weight, and side-effects are consolidated into one timeline for complete historical review.
Trends & Weekly Feedback
Includes 7/30-day weight trends, phase changes, and weekly execution indicators for continuous improvement.
Data Control
Supports CSV export, local data reset, and Apple Health weight sync so users can manage and migrate their own data.
Execution Workflow
A four-step loop from setup to long-term review.
Every action stays traceable: define an executable protocol, activate reminders, log against real timestamps, then iterate with trend and weekly review feedback.
-
Configure Protocol
Select treatment rhythm and reminder times. Required fields must be complete before moving forward.
-
Activate Reminders
Reminder tasks are generated automatically. Weekly protocols can enable T-24 pre-reminders.
-
Execute & Backfill
Log by real execution time. Missed actions can be backfilled without being locked to current time.
-
Review & Adjust
Use trend pages and weekly indicators to evaluate execution quality and adjust reminder strategy.
Use Scenarios
Supports multiple treatment rhythms with lower missed-action risk.
Weekly Protocol
Supports fixed weekly reminders with optional T-24 pre-reminders for predictable weekly routines.
Daily Protocol
For users needing stable day-to-day execution, with persistent reminder mode as a safety layer.
Twice-daily Protocol
Set separate morning and evening reminder times and review interval consistency in the timeline.
Meal-time Protocol
Independent breakfast/lunch/dinner toggles and times for multi-window execution needs.
Product Screens
Real interface captures of key workflows.
Data & Compliance
Data minimization, permission control, and complete policy coverage.
Data Handling Principles
- Core treatment records are local-first and are not sold for ad profiling.
- Apple Health sync only runs after explicit user authorization and can be disabled anytime.
- Export and reset controls allow users to manage their own local data lifecycle.

Can I move my data elsewhere?
Yes. CSV export is supported, and weight data can also sync through Apple Health.
