Store description excerpt
WattKit takes the guesswork out of EV running 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. FIND YOUR EV IN SECONDS Browse our database of 50+ makes, 200+ models, and 600+ variants — with every spec filled in automatically. Just pick your make, model, and variant, and you're ready to go. Can't find your vehicle? You can still add it manually with built-in guides to help you through every field. FULL CHARGE RANGE See your rated range, your current range adjusted for battery health, and estimated winter range across three severity levels — Mild, Typical, and Severe. Know exactly how far you can go before you set off, in any season. JOURNEY COST CALCULATOR Enter your distance and instantly see what it costs to drive using your off-peak, standard, 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 offline after initial setup. An internet connection is needed to load the vehicle database on first use — after that, everything works without one.
