AppMetrica vs NHN Cloud Log & Crash Search

AppMetrica is a mobile-app analytics and growth platform from Yandex, with web, iOS, Android, and API access. It combines attribution, product and marketing analytics, reports, funnel analysis, retention reports, revenue tracking, crash insights, and A/B experiments. Teams can send push campaigns to defined user cohorts. Its SDK records device, session, referral, in-app action, revenue, error, crash, and ANR data. Documented interfaces include Management, Reporting, Logs, Data Stream, Post, and Push APIs. Apphud integration adds purchase and subscription tracking on Custom and Pro plans. The maker says AppMetrica is ISO 27001 certified and offers SDK controls to delay statistics collection until consent. Documented SDK data is encrypted in transit with AES-128, while depersonalized data is stored on Yandex servers in the EU and Russian Federation. The Free plan costs nothing, with stated event quotas and organization-wide limits.

NHN Cloud Log & Crash Search collects and stores logs from client and server applications for viewing and searching. Logs can be sent to its collector over HTTP as JSON, including bulk delivery in JSON-array format. The Log Search API accepts Lucene queries and requires a project secret key in the request header. Searches cover logs from the previous 90 days, and each time range can span no more than 31 days. Results are returned in pages of up to 100 logs; the guide documents paging through up to 100,000 logs. HTTP ingestion requests are limited to 52 MB, while an individual JSON log can be 8 MB. Search usage consumes tokens based on duration, size, and query complexity, with replenishment over time. Source maps are supported. Platforms listed are Android, iOS, web, Windows, and API. Pricing is by custom estimate rather than a stated product price.
