Jolt: Math Puzzle Alarm Clock

Snooze is the reason you're late. Jolt fixes that. Jolt is an alarm app for people who can't be trusted with a one-tap dismiss. To shut it off, you've got to actually wake your brain up first. PICK YOUR CHALLENGE Math, four levels from Easy to Insane. Easy is a sum you could do asleep, which is the problem. Insane is not. Memory, four levels from Easy to Expert. A pattern flashes, you tap it back. Shake, shake the phone until the meter fills. STACK THEM HOWEVER YOU WANT Math Hard plus Memory Easy plus Shake? Sure. Three Insane math problems in a row? Bold. Set a different stack for the alarm you trust yourself with and the one you don't. THE "NICE TRY" CHECK Beat the challenge, fall back asleep? Turn on the wake-up check and Jolt comes back a few minutes later to make sure you're actually up. Add up to five checks, each a set number of minutes after the one before, for the mornings one is not enough. This is the one that catches most people. SNOOZE, ON YOUR TERMS Choose how long each snooze lasts and how many you get. Run out and that is it, the challenge is the only way out. Or switch snooze off entirely and skip the negotiation. TEN SOUNDS, GENTLE TO UNREASONABLE Default, Gentle, Classic and Chime if you're a light sleeper. Air Raid Siren, Battleship Klaxon, Critical Alarm, Arena Buzzer, Vintage Alarm and Doomsday Bell for the hopeless. Or use any ringtone already on your phone, or point Jolt at your own MP3. SET IT ONCE Pick the days an alarm repeats and leave it. Weekdays only, weekends only, one day a week, whatever your week looks like. STREAKS Mornings beaten in a row. Your total, your best streak, and how close you are to breaking your record. Losing a streak to a snooze stings more than it should, which is the point. FOR HEAVY SLEEPERS AND CHRONIC OVERSLEEPERS If you sleep through a normal alarm clock, dismiss alarms without waking up, or cannot wake up without three of them, this is the app for that. Jolt is loud when you ask it to be, and it does not accept a swipe as proof you are awake. IT RINGS WHEN IT SAYS IT WILL Android's battery saver delays or skips alarms, and it is worse on Samsung, Xiaomi, OnePlus and Huawei. Jolt asks once for permission to bypass it, uses exact alarm scheduling, and holds a foreground service while an alarm is actually firing. If your last alarm clock app let you sleep through a meeting, that is usually why. CLEAN DESIGN Light, dark, or system theme. No bloat, no review popups, no nonsense.
