The 2017 crypto market grew faster than its tooling. Retail investors managed portfolios across several exchanges with no unified view: valuations lived in spreadsheets, prices required checking each exchange individually, and incumbent trackers were cluttered desktop-first tools that ignored mobile behaviour entirely. CoinTrack needed an iOS app that answered the core question — total holdings and live value — within seconds of launch, while retaining enough depth for users tracking dozens of assets through extreme volatility.
A two-week discovery phase mapping real investor behaviour: which exchanges people used, how often they checked positions during volatile periods, and which data points mattered at a glance versus on demand. Competitive teardown of existing trackers identified clutter, delayed pricing and absent mobile experiences as the gaps to exploit.
A dark-surface visual system with restrained accent colour reserved exclusively for significant price movement. Information hierarchy placed one number above everything: live portfolio value. Per-coin cards exposed holdings, cost basis and intraday change; secondary detail sat behind progressive disclosure so power features never crowded the first screen.
Native iOS application consuming exchange rate APIs through a lightweight REST layer with client-side caching to survive API rate limits and keep pricing responsive. State designed around offline-tolerant reads so the portfolio view remained useful even when feeds lagged.
A 3-month engagement delivered in three phases: core dashboard and pricing integration (weeks 1-4), per-asset views, watchlists and alerts (weeks 5-9), polish, empty/error states, iconography and store presentation kits (weeks 10-12). Weekly builds reviewed against live market conditions for realism testing.
CoinTrack captured its market window, shipping into the peak of 2017 retail crypto adoption with a differentiated, calm take on portfolio tracking — and the full design-and-build engagement proved out a repeatable playbook for taking a fintech concept from whiteboard to both app stores inside a quarter.
