Wanted to try out the app to see if it would offer something my current CRM doesn’t. Sadly after setting up I got no word of a lie a notification every minute until I deleted the app saying “trail expired? Send us a message” Sure send one or two but one every single minute is excessive. Also the spelling mistake was enough to be off putting in the first instance but to then get all these notifications just really didn’t fill me with confidence moving forward. Maybe just a bug but left a bit of a sour taste. Will maybe check in later down the line as I can see the potential benefits.

The app looks great ! Some really useful features on there and I’m still learning more about it. Wendy has been so supportive with an issue I had when I set up. The app is packed with so much information which will be helpful when completing certificates and sending to customers remotely, this will be a great asset for my business. Highly recommended

Disappointed
rashid the what?
Used to be a great app and relatively cheap, now the prices keep going up, the app crashes frequently, can't use offline mode for certificates, email service reminders no longer work and can't even buy credits for sms reminders, which I don't want to do as I pay already for email reminders as as mentioned before, doesn't update my card details to pay for my subscription when I enter them through the app and needs a phone call which takes time out of my day, really needs to be updated correctly and be what it was and worth the money

Quite often have issues with this, been using over a couple years, 50% of time emails don’t get sent so I have to send them manually, has bugs, when you print the print is so small it’s unreadable, should be A4 size. And now doesn’t sync with server. Also when appliance is safe to use and you click no, it should give an option to At risk/ID warning notice but you have to do manually price has gone up but the app hasn’t improved.
