Vaka – Battery Reminder

Don't let your Apple Watch surprise you. Get a quiet tap before the battery runs low, at the level you choose. No account. No tracking. One-time purchase.

Never get caught with a dead Apple Watch again.

Your Apple Watch warns you when the battery reaches 20%—often too late to do anything about it. vaka gives you a gentle tap at the battery level you choose, so you can charge when it's convenient instead of when it's urgent.

YOUR BATTERY. YOUR RULES. Choose your own reminder level anywhere from 25–90%. Whether you like plenty of margin or prefer to run low, vaka adapts to your routine.

YOUR WATCH DOES THE WORK. Once you've set your reminder, vaka runs directly on your Apple Watch. Your iPhone doesn't need to be nearby. One gentle tap is all it takes.

REMIND ME LATER. Busy? Snooze the reminder with one tap and vaka will remind you again later. No notification spam. No repeated alerts. Just enough.

BUILT FOR APPLE WATCH. See your battery at a glance with a watch face complication. Designed to feel right at home on watchOS.

PRIVATE BY DESIGN. No account. No tracking. No analytics. No ads. No network connection. Your battery data never leaves your devices.

BUY ONCE. One purchase. No subscription. No extra unlocks. Future updates included.

vaka (Swedish) — to keep watch, to stay awake.
