Appily is a good app builder for those who want to create apps for small businesses, but may lack the bells and whistles you may be looking for regarding more advanced apps. I have not uploaded an app to either app store as of yet as I am still in the testing phase, but I will list the features you can add to your app and pros and cons to hopefully help in deciding if Appily is right for you.

Features you can add to your app:
Attendance, Audio, Booking, Cabride, Calendar, Catalog, Code Scan (QR), CommercePro, Contact, Contest, Custom Page (allows for adding pics, buttons, links, etc. to a specific page), Discount, Folders, Form, Images, Inbox, Job, Link(s), Loyalty Card, Magento, Maps, Padlock-Pro, Places (for a directory), Prestashop, Privacy Policy, Push Notifications, QR Coupons, Radio, RSS Feed, Set Meal, Share App, Shopify, Social Wall, Source Code (HTML/CSS), Tips Calculator, Twitter, Videos, Volusion, Weather, WooCommerce, Wordpress.

Here are a list of my pros/cons so far in testing Appily:
Pros:
- Extensive design options and UI layouts
- White Labelling
- Many features needed to market an app to small businesses such as restaurants, etc.
- Unlimited Push Notifications and from my understanding clients can log in to the app and send notifications themselves, unlike another recent app builder sold here on Appsumo which required a OneSignal account for each app.
- Analytics
- Can add your own webhooks
- Good support

Cons:
- No Notepad feature
- Can't add external code (although can add your own HTML/CSS)
- No database connection abilities (would have to link to a website enabled database)

I purchased 3 tiers to get the 100 apps and to be eligible to get the reseller license for 1000 apps and a dedicated support agent (at an additional monthly charge), as I hope to market apps to small businesses in certain niche markets, and I think this is what Appily works well for. I have just started learning Flutter/Dart/Firebase and hope to use those in the future for more robust apps, however.
