You want to get up just before sunrise.
An alarm clock app that wakes you up just before sunrise (based on your location and date.) You set up how much before sunrise you would like to wake up, and how many hours of sleep you need. The alarm will start alerting you to go to sleep based on that (you can also choose how long before going to sleep you want it to start “bugging” you.)
To protect from pickpockets and other thieves.
A “beacon” that you wear on your person that your smartphone can detect. You can turn on the theft protection, and when your phone is taken a certain distance from the “beacon,” it sounds a loud alarm (even if the phone is set to silent mode and the volume is down.) When you put the phone down (at your office for instance), you can switch to motion mode, and the phone will sound the alarm when moved and not when you’re away.
It’s a bore to lock and unlock your bike, especially if you use it a lot.
Have sensors that activate when your bike is at rest and pressure on the wheels/tires is reduces (bike is being lifted.) or bike is in movement. When you park your bicycle, just turn on the system, and if someone tries to lift or move the bike, a loud alarm is activated.
