Why BitDaily matters: the rise of widgets and glanceable UX shifted how users consume market data. Traders and casual holders prefer quick, low-friction updates that don't drain battery or require heavy network usage. BitDaily solves this by using optimized network strategies (ETag, conditional requests), compact JSON payloads, and local caching to reduce API calls while ensuring prices remain timely.
Core technical highlights include a Swift-based widget extension, efficient use of Combine for reactive updates, snapshot-based widget timelines for battery-friendly refreshes, and optional push or background refresh via silent notifications for near real-time updates. The backend supports lightweight endpoints returning precomputed deltas and aggregated metrics to reduce client-side computation.
Quick summary table:
| Feature | Benefit | Typical Frequency |
|---|---|---|
| Live price tick | Immediate price view | On demand / every 1–15 mins |
| Watchlist | Personalized tracking | Real-time-ish via push |
| Compact charts | Sparkline for trend | 24h / 7d |
| Low battery design | Minimal background work | Continuous optimization |

API -> Aggregator -> Cache -> Push -> Widget
Implementation steps
- Define the widget family sizes and the prioritized data for small/medium/large widgets.
- Build efficient endpoints that return compact JSON (symbol, price, delta, sparkline) and support ETag caching.
- Implement the Swift widget extension using WidgetKit and SwiftUI, using timelines for scheduled refresh and Combine for reactive updates.
- Add background silent push integration for high-priority price alerts and watchlist changes.
- Add user preferences for currency, theme, and alert thresholds.
Challenges and mitigations
- API rate limits and cost: reduced by server-side aggregation, delta-only updates, and client-side ETag caching to minimize redundant requests.
- iOS widget refresh constraints: worked within WidgetKit timeline limitations by combining scheduled refresh with silent pushes for critical updates.
- Battery and network usage: minimized by limiting heavy operations to the server and shipping compact payloads; used exponential backoff for retries.
- Data accuracy and latency: used multiple data sources and reconciliation logic to avoid stale or incorrect prices.
