Can I use VoltKeep on the free plan?
Yes. Route maps, energy efficiency tracking, automatic trip detection, monthly trends, phantom drain detection, widgets, and push notifications are all free. Only the AI analysis features are Pro-only (AI Driving Score, monthly AI report, route-based efficiency comparison, battery degradation forecasting, and data export). Pro is $2.99/month or $29.99/year (about two months free). App Store handles regional pricing automatically, so amounts may vary by country.
What's included in the free plan
VoltKeep's free plan isn't a stripped-down "trial." It's a fully usable build that covers the core driving-data analytics workflow.
- Real-time dashboard — battery level, cabin temperature, and current location at a glance
- Apple Maps route view — routes color-coded by speed
- Energy efficiency tracking — average Wh/mi (or Wh/km) per trip, fully logged
- Automatic trip detection — parking and driving auto-detected and logged
- Monthly trends — distance driven, efficiency, and energy charged, summarized monthly
- Phantom drain detection — automatic alerts on abnormal parked battery loss
- iOS widgets — battery level on Home Screen and Lock Screen
- Push notifications — charge complete, drain anomalies, trip summaries
Pro-only features
Everything that requires AI or predictive modeling is in the Pro tier.
- AI Driving Score — driving patterns analyzed by an LLM, with concrete improvement suggestions
- Monthly AI report — a one-page summary of your month with recommendations
- Route-based efficiency comparison — same route compared against past trips to measure progress
- Battery degradation forecasting — estimated SoH (State of Health) and projected degradation curve
- Data export — CSV / GeoJSON export of your driving data

Are there time or usage limits?
The free plan has no "expires after 30 days" or "history capped at X days" gotchas. As long as VoltKeep is installed, free-plan features stay available forever.
That's a deliberate contrast with HedgieMate (free tier limited to 14 days of history) and TeslaFi (paid after a 30-day trial) — VoltKeep is built to be usable for free over the long term.
