When should you get started? Just ask Whendy. No more time math: Start with a target time and then work your way back. It’s that simple! Time math is hard Do you sometimes get started too late? Ever arrived late to an appointment? Almost missed a flight? Or unnecessarily waited at the gate for hours? Sometimes you know when you need to be done, and you know how long each step takes. But it’s hard to do the math in your head and know when to start. Whendy makes it easy! Why Whendy? For many daily tasks, a proper project planner is overkill, a calendar seems clumsy, and a to-do list won’t tell you when. Whendy is a simple, clean, text-based way to plan out when to start each needed activity to arrive on time for your crucial event. It’s easy to make a plan Check out the screenshots and you’ll get it right away. Just type in your target time (when will your flight board?), and list the durations of steps before (from airport to gate 90 min, get parking 45 min, …, pack 60 min). Done! Whendy tells you when each step will begin and end, and when to start with step 1. Is Whendy for you? • Are you frustrated by time math where you are adding or subtracting times? • Do you like the effectiveness of a to-do list? • Do you like to keep it simple yet well thought-through? Then yes, Whendy is for you! *Whendy Premium*  • import events from your calendar. Quickly start a new plan without typing in the starting or ending time • export activities back to your calendar.  Premium is free for the first couple of uses so you can try it out without committing to anything.

Verdict

The call

The clearest difference is review sentiment: Whendy Fast Time Planner at 100% against Autoterm Control's 36%. Whendy Fast Time Planner also leads on update cadence (every 3 weeks vs every 3 months) and ratings volume (11 vs 2). Autoterm Control's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.8). On price, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Autoterm Control holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Whendy Fast Time Planner has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 36% of Autoterm Control's written reviews are positive against 100% of Whendy Fast Time Planner's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Autoterm Control ships an update every 3 months, Whendy Fast Time Planner every 3 weeks. The most recent releases landed on September 21, 2026 and September 8, 2026 respectively.
