WattKit takes the guesswork out of EV ownership costs. Whether you're calculating your daily commute, comparing two electric vehicles, or tracking how your battery ages over time — WattKit gives you clear, honest numbers you can trust.
NO IN-APP PURCHASES. NO SUBSCRIPTIONS.
Pay once, own it forever. Every feature unlocked from day one.
BUILT FOR PRIVACY
No tracking, no analytics, no third-party SDKs. Your data syncs privately via your own iCloud account.
YOUR EV, ANY EV
No vehicle database — you enter your own specs. That means it works with any EV, anywhere in the world, and never goes out of date. Just three details to get started: vehicle name, battery capacity, and efficiency. Not sure where to find them? Built-in guides walk you through every field.
JOURNEY COST CALCULATOR
Enter your distance and instantly see what it costs to drive using your home, work, or public charging rates. Adjust for real-world conditions like winter efficiency loss, and see exactly what you pay per mile. No more spreadsheets, no more guessing.
COMPARE ANY TWO EVs
Put any two electric vehicles side by side and see every difference that matters — battery capacity, range, efficiency, charging speeds, and journey costs. Making a buying decision? WattKit gives you the full picture in seconds.
UNLIMITED PDF REPORTS
Export your comparison as a detailed, professionally formatted PDF report. Share it with family, friends, or your dealer — via AirDrop, email, WhatsApp, or any app on your phone. No limits, no paywalls. Every export is free, every time.
BATTERY HEALTH TRACKING
Track your battery's estimated health over time based on its chemistry type — whether that's NMC, NCA, LFP, or LMFP. Understand how age and usage affect your usable capacity, so there are no surprises down the road.
WINTER MODE
Cold weather reduces EV range. WattKit uses research-backed efficiency loss data to show you realistic winter journey costs, not the optimistic figures from manufacturer brochures.
WIDGETS & APPLE WATCH
Check your journey cost at a glance with home screen widgets in three sizes. The Apple Watch app puts your costs on your wrist — with a complication for your watch face, vehicle switching, and full journey cost breakdowns.
SAVINGS CALCULATOR
See how much you save compared to a petrol or diesel vehicle over any distance. Perfect for convincing yourself — or someone else — that going electric makes financial sense.
Works entirely offline. No internet connection required.
