ServerShelf

ServerShelf for iPhone and iPad is the companion to ServerShelf on your Mac, Windows or Linux machine. It carries your full server inventory with you: every server with OS, provider, environment and tags, SSL certificate expiry, uptime checks, pending updates and reboot flags. WHAT YOU GET β’ Inventory: your whole fleet at a glance, grouped by project, with search and per-server detail down to hardware, services and domains. β’ Triage: one screen with everything that needs attention: certificates about to expire, uptime checks that are down, servers with pending or security updates, hosts waiting for a reboot. β’ Library: your snippets and software licenses from the desktop, readable wherever you are. β’ Live on your LAN: pair with the desktop by scanning a QR code and get live data straight from it while you are on the same network. β’ Push alerts: the desktop can notify your phone when something needs attention. HOW IT CONNECTS The desktop app encrypts a snapshot of your inventory and puts it in storage you own: iCloud Drive, any S3-compatible bucket, or a WebDAV share. This app downloads that snapshot and decrypts it with your passphrase. There is no ServerShelf cloud and no account. PRIVATE BY DESIGN End-to-end encrypted: the passphrase stays on your devices, and the storage provider only ever sees ciphertext. No tracking, no telemetry. REQUIRES ServerShelf for desktop (servershelf.app) creates and uploads the snapshots. This companion app is free.

Verdict
The clearest difference is ads: ServerShelf at none against Device IMEI's shown. ServerShelf also leads on update cadence (every 4 days vs every 5 weeks). Device IMEI's advantage is iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.
