Cold chain reinvented

Stop losing
trials to
blind spots.

ReuseLogger turns an Android phone into a real-time clinical trial temperature logger. No disposable hardware. No post-shipment surprises. No excursions you can't act on.

Timestamped audit trail

Real-time. Not post-mortem.

Traditional loggers tell you what happened after delivery. ReuseLogger tells you what's happening right now — so you can intervene before a shipment is lost.

The old way is broken.

Disposable data loggers haven't fundamentally changed in 20 years. Clinical trials have.

✕  Legacy loggers
Excursions only visible after delivery — too late to save product
$50–$300 per unit, discarded after every shipment
Requires proprietary reader hardware to extract data
Manual data extraction invites transcription errors
Growing e-waste footprint across every trial
✓  ReuseLogger
Real-time alerts the moment a temperature threshold is crossed
Runs on existing Android phones — hardware you already own
Data exports directly from the app — no special reader needed
Automatic timestamped logs eliminate manual transcription
Reusable hardware: dramatically reduced waste per trial

Four steps. Zero guesswork.

ReuseLogger combines precise sensing hardware with a purpose-built Android app.

Step 01

Connect hardware

Plug the probe into your Android device via USB-C. ReuseLogger detects it automatically.

Step 02

Start a shipment

Log shipment details, set temperature thresholds, and begin monitoring in seconds.

Step 03

Get instant alerts

Any excursion triggers an immediate alert and auto-logged event. Intervene before product is compromised.

Step 04

Export audit trail

Generate a complete timestamped chain-of-custody record ready for regulatory review.

Built for the people who know the stakes.

Every feature exists because a real clinical supply professional felt the pain of the alternative.

Dramatic cost reduction

Replace $300 single-use loggers with Android hardware you already own. Scale to dozens of shipments without multiplying hardware spend.

Real-time intervention

Traditional loggers are forensic tools. ReuseLogger is a prevention tool. Know the moment a threshold is crossed — not days later at delivery.

Regulatory-grade records

Auto-generated, timestamped logs with full chain-of-custody data. Designed for audit readiness from day one.

Truly reusable

Ship, retrieve, and redeploy. No more ordering a new logger for every cold chain movement.

No special reader hardware

Data lives on the Android device and exports directly. Anyone with the app can retrieve a full shipment report.

Sustainability at scale

Clinical trials run hundreds of shipments. ReuseLogger eliminates e-waste generated by single-use devices across every trial.

Built for the regulatory environment.

Designed from the ground up to produce documentation that holds up — not adapted from a generic IoT solution.

Clinical trial supply teams operate in one of the most scrutinized regulatory environments in the world. ReuseLogger was designed from the ground up to produce documentation that holds up.

Every temperature reading is timestamped, every excursion is auto-flagged, and every shipment generates a complete exportable record — ready for sponsor review, regulatory submission, or audit response.
