What a lab should know before using CryoIndex.

CryoIndex is an offline-first Android tablet app for locating and tracking cryogenic cell vials in research laboratories. It records each vial’s configured dewar, cane, box and grid position, together with the history of changes made to that record.

CryoIndex is designed around one shared lab tablet and one authoritative on-device inventory. Lab members are named inside the app so moves, removals, audits, liquid-nitrogen fills and corrections retain who recorded them. It does not currently synchronize a live inventory between several tablets or personal phones.

No account with CryoIndex is required, and the core inventory works without an internet connection. Google Play connectivity is still needed for installation, updates and purchase services when applicable.

The first release is for Android 7.0 or later tablets and runs in landscape orientation. CryoIndex does not currently support Android phones, iPhone, iPad, Windows or Mac.

Yes. The interactive website demo uses the real CryoIndex interface with a complete fictional lab. Plus features are available for exploration, but importing files, saving exports, camera access and purchases are switched off. Each browser tab has its own temporary in-memory database, and reloading or closing the tab discards every change. The demo is intended for a desktop or landscape tablet at least 700 pixels wide and has been formally verified in Chrome; Firefox and Safari are not yet claimed as tested browsers.

The working database remains on the tablet. CryoIndex does not upload it to our servers, and the app excludes it from Android cloud backup and device-transfer services. A file leaves the app only when the lab deliberately saves, exports or shares it through Android.

CryoIndex keeps automatic safety copies on the tablet, but those cannot survive loss or failure of the entire device. The lab should regularly save a complete backup to a separate, institution-approved destination and verify that the file exists there.

Install an equal or newer CryoIndex version on the replacement tablet and restore the newest complete backup. CryoIndex validates the file before replacing anything. After restoration, the lab should verify several known vials, users and storage locations before returning the tablet to service.

Yes. CryoIndex Plus is a one-time purchase, and a complete backup preserves the lab’s Plus unlock when restored to a replacement tablet. This provides a recovery path when Google Play purchase restoration is unavailable. It is intended for replacement and disaster recovery; it does not synchronize separate tablets or create a shared live inventory between them.

Yes. CryoIndex imports CSV inventory during initial setup or later from Settings. It reviews column mappings and previews what it understood before writing. Rows it cannot safely place are explained rather than silently forced into the inventory.

The first release is designed for liquid-nitrogen storage arranged as dewar, cane, box and vial position. Each dewar can have its own configured cane, box and grid dimensions. Support for −20 °C and −80 °C mechanical freezers is being considered separately because those laboratories may need different locations and temporary checkout-and-return workflows.

Free provides a complete inventory for one dewar, including storage and retrieval, batch entry, scanning, box audits, activity history, CSV import and export, and backup and restore. Plus is a $49.99 USD one-time upgrade that adds multiple dewars, Audit & QA PDF and CSV reports, and an optional admin PIN for high-impact actions. Google Play displays the applicable local price before purchase.

No. CryoIndex is research-laboratory inventory software for cryogenic cell storage. It has not been designed, validated or marketed as clinical laboratory software.
