Never get caught on empty again. Battery Nudge is a beautifully simple reminder that tells you to plug in before your phone dies — not after. Choose the battery level that matters to you, pick how loud the reminder should be, and let Battery Nudge quietly watch your back. WHY BATTERY NUDGE • Set your own threshold — Get nudged at 20%, 30%, 50%, or any level you choose. • Three reminder styles — Calm for a gentle heads-up, Firm for a direct prompt, or Emergency for an alert that's impossible to ignore. • Repeat reminders — Keep getting nudged every 10 minutes until you actually plug in. • Quiet hours — Mute reminders while you sleep so you're never woken up. • Light & Dark themes — A clean, minimal design that looks great day or night. PRIVATE BY DESIGN Battery Nudge runs entirely on your device. No account, no sign-up, no tracking, and no internet connection required. Your settings stay on your phone — that's it. SIMPLE AND FOCUSED No clutter. No ads interrupting you. Just one job done well: making sure a dead battery never catches you by surprise. Set it once and forget the anxiety.
