IFTTT is easy to set up, but with limitations. And though Stringify allows for complexity, it can scare it with its flows, chains, and modes. Yonomi is a great alternative that makes complexity easier with simple routines.
What distinguishes Yonomi
Yonomi (pronounced You Know Me) starts very much like IFTTT. You connect devices, services, and accounts that the app can access. And then set up automation (called routines here), "if that happens, perform this action."
Where Yonomi differs from IFTTT is that you can have multiple "when" triggers and add a "just" clause to Yonomi's clause. For example, you could set up a routine to lock a door when you leave the house, but only if it is a weekday and it is before 8:00 in the morning. The only downside is that although you can combine multiple "but only" clauses (because it's a weekday and a certain time ago), the multiple "when" triggers are always treated as an OR scenario.
In addition, Yonomi has taken a completely different direction in the integration of Alexa and Google Home. With Alexa, all the routines you do in Yonomi are shown as devices in the Alexa app. This allows a more natural syntax and you can integrate Yonomi routines into Alexa routines. With Google Home Yonomi has taken special note of the syntax. There is no reference to Yonomi required. In addition to being able to say "Enable (routine name)", you can use "power on" and "power off" with the same routines. This means that if you have a routine labeled "All On" and "All Off," you can tell Google to turn everything off and turn everything on to control your devices.
Once you've downloaded the Yonomi app for iOS or Android, you'll need to create an account. Yonomi then makes it incredibly easy by immediately trying to discover all the devices on your Wi-Fi network to which it can connect. Just follow the instructions to end the connection of all accounts or devices. Then add your address for geofencing. If for some reason not all accounts or devices are automatically detected, you can manually add them.
Tap on the Hamburger menu in the upper left corner first.
Tap Accounts & Hubs.
Tap the plus in the lower right corner.
Select the account you want to add and enter the credentials If you have other devices that do not require login credentials, or if you've added new devices to an existing setup, you can search for devices by simply tapping the Hamburger menu again and selecting "Search for new devices." 1963004]
Yonomi should automatically find all the new devices in your network Yonomi supports Wink, Nest, Withings, Honeywell, Beat and more If you've got everything together, you can start building powerful routines.  Creating a Routine
If you have created an applet in IFTTT, creating a routine in Yonomi is familiar to you, although it does include some optional options. We will show you how to create a routine for locking the door when leaving the house.
To create a routine, tap the "Routines" button at the bottom of the app.
Here you can see all the current routines, and you can tap on the plus to add new ones.
Start by naming the routine, and then tap the plus under "When."
Touch the Location button.
Tap the "I Leave Location" option.
right then select your home town.
After selecting your home location, tap the "Add action" plus sign under the "Perform these actions" section.
Select the blocking device you want to use. Here we choose a castle, which we have already set up and have the name "Front Door".
Select the "Lock" option.
Now On Again On the main Create Routine page, a "but only if" condition is set up. Click the "Add condition" button in this section.
Tap the "Date & Time" option.
Tap the "It's a weekday" option. 
To add a second condition, tap the Add Condition icon again. We choose again the category "Date & Time" and this time we add the option "It's before Time".
Then tap the gear to the right of "It's Before Time" to make the setting correct time.
If everything is there, tap the check mark to complete the routine.
If you leave the house now, it is a weekday and it is before 8 o'clock: 00 o'clock, your door will be locked. When you're the last, you do not have to worry about keeping the door locked. Of course, this is just one scenario out of many that you could set up, but it's pretty fair example of a shared activity that you can improve with Yonomi. Smooth integration with so many devices, the ability to use multiple "when" applications, and adding "if only" conditions make Yonomi a pretty powerful app that lets you automate your SmartHome.
Yonomi is not perfect. Like any other automation app, it can not tell you if you're the only person in a home. And because it is not possible to combine multiple triggers in an AND sequence, the full potential can not be achieved. It does not connect with everything. Wink integration is available, but not for smartthings (although the list of integrations is growing.)
However, Yonomi's intelligent Voice Assistant integration and ease-of-use make it highly competitive with other automation apps. If IFTTT is not powerful enough and Stringify is intimidating, Yonomi might be the solution you were looking for.
