TimeHack
Read full descriptionHide full description
Make your own time work for you. The day fills up and disappears. You studied hard, but you cannot really feel how far you got. TimeHack is a deliberately simple time log that turns those hours into something you can see. WHAT IT DOES Simple to record. No setup, no accounts. Add an entry and mark it done. Analysis that fits the question. Today, this week, this month, this year - your time is totalled up for you automatically. Progress you can see. Study, reading, training: watch the hours add up as a chart. "I actually did this much" is what carries you into tomorrow. Find the time you were losing. Once the aimless hours are visible, your days settle into a rhythm on their own. GOOD FOR - Logging study for an exam or a qualification - Tracking billable or side-project hours accurately - Anyone looking for a simple tool to build a habit - Ending the day with something to show for it BUILT TO STAY OUT OF THE WAY Recording should never feel like work, so everything unnecessary has been stripped out. Every time you open the chart, your effort is right there. Your entries stay on your device. Nothing is sent anywhere. Export to CSV any time from Settings.

Your watch taps you the moment your eyes close. EyeJolt watches your eyes with the front camera and nudges you awake the second you start to drift โ a buzz on your wrist, a sound, or both. Prop your phone up, start a session, and get on with your work. WHY A WATCH CHANGES IT A phone buzzing on a desk is easy to sleep through. A watch against your wrist is not. Pair an Apple Watch and jolts arrive as haptic taps โ quiet enough for a library, a lecture hall, or a shared office, and set to Gentle, Standard or Strong depending on how deeply you go under. READING DOES NOT SET IT OFF Most drowsiness apps are built for drivers, who sit head-up. Put one on a desk and it cries wolf the moment you look down at a book or a keyboard. EyeJolt watches your eyes, not just your head angle. Reading with your head down does not trigger it. Closing your eyes does. IT DOES NOT GIVE UP AFTER ONE BEEP A single buzz is easy to sleep through. EyeJolt escalates: a nudge first, then a firmer alert, then a full jolt that keeps going until you acknowledge it. It catches you dozing off sitting upright, not only when your head drops. A SOUND BANK BUILT TO WAKE YOU (AND MAKE YOU LAUGH) - Startle classics: air horn, klaxon, referee whistle, gong - Absurd chaos: screaming kazoo, slide-whistle-into-crash, record-scratch boom - A calm, serious set for when you just need to focus โ no circus - Record your OWN alarm in your voice (or a friend's), add it to the mix, and share the clip in one tap SILENT JOLT Need to stay quiet? Silent Jolt drops the sound and wakes you with haptics alone. It is less forceful by design, so it does not go it alone: if a jolt goes unanswered for 20 seconds the alarm sounds anyway. You can switch that backstop off if you need true silence โ the app tells you exactly what you are giving up. PRIVATE BY DESIGN Everything runs on your device. The camera feed is processed live and never recorded, saved, or sent anywhere. No account. No cloud. No frames ever leave your phone. MADE FOR Students in late revision, night-shift workers and nurses, remote workers fighting the afternoon slump, and anyone who keeps losing the last hour of the evening to a doze. EyeJolt is a wake-up aid, not a guarantee. It is not a medical device. It needs the screen on and the camera facing you, and it is not intended for use while driving. STARTING IT ON THE WATCH Open EyeJolt on your Apple Watch and tap Start on wrist when you sit down. Apple only lets a watch app buzz you with your arm down while that session is running, and it lasts up to an hour โ the watch tells you when it is nearly up. EYEJOLT PLUS EyeJolt Plus unlocks the full sound bank, Silent Jolt, and Apple Watch haptics. Available as an auto-renewable subscription (monthly or annual) or a one-time lifetime purchase. Payment is charged to your Apple ID at confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period; manage or cancel anytime in your App Store account settings. Detection stays free, and so does recording your own alarm. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://geteyejolt.com/privacy

Verdict
The clearest difference is in-app purchases: TimeHack at none against EyeJolt's 3. TimeHack also leads on iOS requirement (13.0 vs 17.0). EyeJolt's advantage is ads (none vs shown) and update cadence (every 4 days vs every 3 months). On price and device support there is nothing between them.
