First ThingGo to bed knowing your alarm is right.
First Thing is an alarm clock app for Android and Wear OS that works out when to wake you. Keep your calendar up to date and it does the rest: one alarm each night, a bedtime to match, and the reason why. No calendar? Your usual week is enough.
Free. Pro free for 14 days, no card.
The bedtime admin
Tonight, skip
all of this.
No checking your calendar in bed. No working out when to leave. No setting an alarm, and a second one just in case. First Thing has done it before you've thought about it.

- 22:43Work out when you'd need to leave
- 22:44Check the traffic for the morning Pro
- 22:46Count back how long it takes to get ready
- 22:48Set an alarm, then a second one just in case
- 22:49Check the volume's up and Do Not Disturb won't block it
- 22:51Work out what time you should be asleep by
- 22:52Remember to switch it off for Saturday
It's handled. Just go to bed.
When tomorrow's calendar needs an earlier alarm, free asks you with one tap. With Pro, it moves it by itself and checks the traffic.
Every morning is different.
Your alarm should know.
Night shifts, school runs, early flights, a lecture that doesn't start till eleven. First Thing works out the right time for each one.
Keep your calendar up to date. First Thing does the rest.
A dentist appointment, a late start, a day off. Add it to your calendar when you book it and get on with your day. Tonight, First Thing works out tomorrow's alarm and bedtime from what's actually on.
Free asks you with one tap. With Pro, it moves the alarm by itself and tells you why.
It shows its working.
Every number is yours to change. Tap one, and choose whether it's just for tomorrow or every school day.
It notices.
You decide.
A dentist appointment lands in your calendar. You keep getting up later than your alarm on Fridays. First Thing spots it and asks, and nothing changes on a guess. With Pro, it moves by itself and tells you exactly why.

Set your week once.
It handles the exceptions.
Give it your usual times and it plans every night, bedtime included. No calendar? It works from your week alone. Got one? It can only ever wake you earlier.
Woken by your wrist, not the whole room.
On Wear OS, your watch buzzes first. The phone only joins in two minutes later if you don't answer, or straight away if the watch isn't connected. Stop it on either and both go quiet.
- A tile with tomorrow's alarm, the reason, and −15 / +15
- Change or skip tomorrow with the crown
- Smart wake with Pro: already stirring? It buzzes up to 20 minutes early, never late
An alarm is only
as good as its ring.
Phones restart overnight. Battery savers close apps. Volume gets left at zero. First Thing was built and tested around every one of them.
Rings after a restart
If your phone restarts overnight and stays locked, your alarm is set again before you unlock it.
Warns you the night before
A permission switched off, or Do Not Disturb blocking alarms? You'll hear about it in the evening, with a Fix it button.
Vibrates even if sound fails
Vibration starts on its own. If your tone can't play, it falls back to another sound.
Tries again
Not answered? It rings twice more over about 25 minutes, then tells you it stopped.
Keeps a backup
On an earlier-than-usual morning, your usual time stays set as a backup alarm.
Quiet with one press
One tap on I'm up stops it. Any volume button snoozes it. No puzzles, no maths before breakfast.
What time should I go to bed?
Count back from your alarm: the sleep you need, plus time to drop off. First Thing does it every night, and eases bedtime earlier before an early start, by an hour at most.
8 hours of sleep and 15 minutes to drop off.
What testers say.
First Thing has been in a closed test on Google Play since October 2026, with testers in the UK, Germany, Italy, Spain and India.
It has become my default alarm app now. I barely need to think about it: it reminds me, updates me, and makes it easy for me to change things through notifications.
Awesome aesthetics and does what it says… getting you up at the right time for your day based on your schedule.
I don't have to interact much with it.
A nice alternative to the built-in alarm.
The alarm is free.
It's never behind a paywall.
Every new install gets 14 days of Pro, no card. After that, everything in Free is yours to keep.

Good to know
Do I need to use a calendar?
No. First Thing starts from your usual week. A calendar is optional, and it can only ever wake you earlier, never later.
Won't a different alarm every day upset my body clock?
It would, so First Thing doesn't do that. Most mornings your alarm is your usual time. Your calendar can only bring it earlier, bedtime moves by an hour at most, and lie-ins stay within an hour. How it keeps your body clock steady
Will it change an alarm I set myself?
Never. A time you set by hand stays put. Anything it works out, it explains, and anything it isn't sure about, it asks.
Does it work for shift work?
Yes. Set early, late and night shifts in your week, and it plans day sleep after nights and the switch back to days.
Is it free?
Yes. The alarm, your week, bedtime, suggestions and the Wear OS app are free for good. Pro adds the alarm moving by itself, live traffic, leave-by, smart wake and the sleep coach.
What leaves my phone?
Your calendar and sleep stay on your phone. No ads, no analytics, no account. Live traffic (Pro) sends only the start and end of the trip, and the sleep coach uses Google's cloud only if you switch that on.
Is there an iPhone version?
Not yet.
