Watch 4 my Phone - Lost Alert 4+

Worth it

The app is quite effective. It notifies you when you lose Bluetooth connection with your phone. While there are a few initial teething problems, once you get the hang of it, it works well. Even with reduced location accuracy, it functions effectively without significantly draining battery life. The main drawback is that it prevents sleep mode if left on overnight; if sleep mode is important to you, you'll need to manually turn the app off at night and back on in the morning.

Works.... sporadically

Had high hopes for this app. Unfortunately it does work, but sporadically. 80% of the time it WILL alert you to leaving your iPhone behind. But let’s be honest. 20% of the time is plenty to leave your phone on a cluttered restaurant table, or at home - only to lose it permanently, or just have the inconvenience of returning home for it. Then there’s it’s main flaw.....IT EATS BATTERY LIFE
I can get 2 days out of my iPhone (but usually charge it daily) & easily a full day out of my Apple Watch 6 (charge it last thing at night for 2 hours).
With this app running my “dormant” Apple Watch is down to 30% charge, from 100% by the time I get up at 6am. My iPhone that lasts 2 days is down to 40% in 8hours. This app will warn you of various states of your watch & iPhone battery. It’s a good job. You’ll be charging both very, very frequently....
I removed the app from my watch & phone & the battery life of both was immediately restored!
The potential is certainly there. But it’s not “real world” usable yet....

Developer Response ,

I have good news. I found the problem which in some cases didn't deliver Lost Alert notification.
New version 2.6.0 with bug fix is ready for download on App Store.

New in version 2.6:
- The app now sends Multiple iPhone Lost Alerts until the user either acknowledges the alerts or a user defined maximum number of alerts have occurred (or the Watch reconnects to the iPhone). Instead of Lost Check Frequency settings "Num of tries" and "Time between tries (s)", there are now Lost Alert Frequency settings "Num of alerts" and "Time between alerts (s)" which defines maximum number of alerts and a delay between alerts in seconds. User can acknowledge the alerts by selecting "Mute until Found" on iPhone Lost alert, to not receive further alerts.
- Bug Fix: The app didn't sent new iPhone Lost Alerts if the app was not opened after reconnecting to the iPhone.

There is also app setting to use less battery. If you change "Location Accuracy" to 1 or 3 kilometres, App will not use GPS for location updates, but it will still refresh location frequent enough and with Wi-Fi enabled, location will be enough accurate in urban areas. On the other hand, If you change default "Location Accuracy" settings from 100 meters to more accurate (for example Best or For navigation) this can result in really high battery consumption.

3 feature ideas

This is one of the best apps in the App Store, I’m liking the emoji symbols on the watch complication i.e. info graph watch face, three features I would like to see are an iOS 15 widget which shows battery levels of watch and iPhone, Traffic light colours for the Apple Watch gauge and also battery level in numbers with percent for the gauge

Developer Response ,

Thanks for the feedback. It really means a lot to me. I will continue to upgrade the app to make it even more functional and user-friendly.
