Beautiful logs and crash reports for your app. Without the enterprise bill.
GrenLogger captures every log, error and crash from your iOS, Android and Web apps — then turns them into insights by version, device and country that Crashlytics will never show you.
Free plan, no credit card. Native SDKs for iOS, Android.

See what Crashlytics hides in the metadata.
Every log you send carries app version, device, OS and country. GrenLogger promotes them to first-class breakdowns so you catch bad releases before your users tweet about them.
Release health
Error rate per app version, side by side.
Devices & OS
Top devices crashing your app, split by platform.
Geography
Traffic and errors grouped by country code.
Everything a mobile dev actually needs. Nothing more.
The features you would stitch together from Crashlytics, Sentry and Logtail — delivered as one product with one bill.
Live tail
Stream logs from your device in real time. Toggle it on when you need it, off when you do not — zero idle cost.
Automatic error grouping
Stack-trace fingerprints collapse thousands of reports into a handful of root causes. Sentry-style, without the Sentry invoice.
Release comparisons
Compare crash-free sessions between two versions side by side. Ship with confidence, rollback with evidence.
Remote log activation
Ship with remote logging off by default. Flip it on from the dashboard for one user when you need a trace — privacy-first.
Search everything
Full-text search across all your logs, combined with filters by version, device, country and fingerprint.
Smart email alerts
Error thresholds with built-in cooldowns. No midnight pages for transient spikes you already fixed.
SSL pinning & SDK signing
Dynamic certificate pinning with cryptographic signature verification. Your payloads stay yours, end to end.
Multi-tenant projects
Organise logs by project, invite your team, slice by environment. Works for a solo indie or an agency with ten apps.
Team & roles
Role-based access control on every tier. Invite the whole team, scope each member to the projects they own — no cross-selling nonsense.
One API. Every platform you ship to.
Swift, Kotlin SDKs with the same surface. Copy, paste, ship.
