A slow app loses users at a measurable rate: 53% abandon if the app takes more than 3 seconds to respond. Performance problems have concrete causes and, in most cases, can be resolved without rewriting the product from scratch. Before making any costly decisions, you need a rigorous technical diagnosis that separates symptoms from root cause.
The most common culprits are unvirtualised lists rendering thousands of items, API calls blocking the main UI thread, unindexed database queries that scale poorly with data volume, uncompressed full-resolution images, and state management architectures that rebuild the entire widget tree on every change. Dribba identifies the exact problem, quantifies it, and resolves it with before/after benchmarks.

Frequently asked questions
Apps degrade through accumulated technical debt: code added without refactoring, database queries that scale poorly, outdated dependencies, and architectures not designed for the current data volume. Degradation is gradual and typically becomes critical when the user base grows. A technical audit quantifies the problem before the damage compounds further.
In the vast majority of cases, yes. The Pareto principle applies to performance: 20% of problems cause 80% of the slowness. Identifying and fixing them is far cheaper than a rewrite. Only when the base architecture is fundamentally flawed does a partial or full rewrite make sense — and a technical audit answers that question with data, not opinions.
A performance audit costs between €3,000 and €8,000 depending on app complexity. Remediation ranges from €5,000 for targeted fixes to €30,000+ for deeper refactoring. We always start with the diagnosis — the cost of not knowing is greater than the cost of finding out.
The technical audit is delivered in 2–3 weeks. Optimisation itself depends on scope: targeted improvements (virtualisation, caching, query indexing) take 2–4 weeks. State architecture refactoring or larger migrations can take 2–3 months. The process is always incremental — the first improvements are visible early.
