EchoStack vs AppsFlyer
AppsFlyer's pricing model confuses even their own customers — bills jump from hundreds to thousands with disputed conversion counts. EchoStack uses simple MAU-based tiers with every feature included. Fraud detection, raw data, cohorts — all of it. On every plan.
Based on reviews from G2 (680+ reviews), Capterra, Trustpilot, and TrustRadius.
The #1 complaint across all review platforms. Reviewers report unexpected billing escalations with significant discrepancies between AppsFlyer's conversion counts and their own data. The "capacity credits" billing model is widely criticized on review platforms for its complexity.
AppsFlyer scores 4.5/5 on G2 (enterprise reviewers with dedicated AMs) but 1.5/5 on Trustpilot (smaller teams). A $15K/year customer had service disabled without warning and spent a week unable to reach anyone. Smaller customers report generic replies and upselling instead of problem-solving.
Protect360 (fraud detection), Data Locker (raw data export), predictive LTV, and cohort analysis all require paid add-ons on premium tiers. Features that should be table stakes are gated behind enterprise pricing. One user noted AppsFlyer "upsells every step."
Reviewers on Trustpilot report continued charges after cancellation requests. Early termination fees, cancellation terms, and post-cancellation data access windows are not publicly disclosed — described as a "significant transparency gap" by industry analysts.
Some reviewers report AppsFlyer's install counts exceeding their App Store totals — a discrepancy that may stem from different counting methodologies but that users find difficult to reconcile. Discrepancies of up to 40% with certain ad networks have been reported.
Reviewers describe initial impressions marked by "complexity and difficulty of use." Shows only one platform (iOS or Android) at a time — no unified view. Cannot create custom metrics or charts natively. Reports load slowly with large datasets.

| Attribution transparency | Limited visibility into attribution decisions | Visible confidence scores and match factor breakdowns |
