### 1/5 — Don’t forget log in details

*2025-01-31, version 13.60*

If you have forgotten what email you used to register, you are locked out and unable to re register due to already using the gas safe number

### 5/5 — Great Job

### 5/5 — Gas checker review

*2022-01-29, version 13.1*

Great app great customer service and support !

### 1/5 — Software difficulties

*2021-03-05, version 12.1*

Used this App for 8 years. A few bugs here and there. Latest one is. Cannot open App on my iPad with iOS 10.3 even when stating on all app details that it can. I think the team needs to address this. Their advice was for me to buy another iPad or just use my iPhone. Ok, so I resurrected my old iPhone 4 on iOS 7, it downloaded the App after it said the iOS was too old and could load an earlier version of the App. This contradicts what the tech helpline was saying. If I can run an iPhone 4 with iOS 7 with the App, how come my ipad won't run it? Anyone else had such issues? Mr disgruntled.

### 5/5 — AMAZING!!

*2020-11-13, version 11.7*

I've been using this app since 2012 , I do hundreds of cp12's every year and it sends reminders to customers by email. I use it for all my invoices, warning notices and CP12’s. It has been amazing as I’m useless with paperwork! Everything is stored and if any issues the technical is amazing ( I just asked for my clients invoices for last tax year and they send a spread sheet! WOW!
I had 8 years on this app and the cost of around £10 per month is too cheap. I lost my phone last year and they simply back up all my 7 years to the new phone.
Best thing ever for Gas engineers.

### 1/5 — Latest update June 20

*2020-07-10, version 11.0*

Now the app crashes instead of opening.  
Finally opened after connecting ipad to internet but then started crashing again.   Still waiting for an update to fix  the last update.

### 2/5 — Can’t get past the make a profile picture bit

*2020-07-05, version 11.0*

Updated and now can’t get past add a profile picture the cancel will not work and the x 

Updated because I imported all info from a works I pad which is really slow 
It imported all the files just no names and addresses of the properties 

Which is no good if you want to renew a certificate 
Will have to stick to the slow I pad it seems

Support does not seem to want to help with any questions 

Not great 😫

### 3/5 — Faults since update

*2020-06-30, version 10.6*

Worked great until update. Now can’t use. Hopefully bug will be fixed shortly

### 1/5 — Used to be ok

*2020-06-28, version 10.4*

After 5 years of using this app I’ve just moved to a different app. Massive price hike for a pro user compared to other apps, incorrect dates on certs making the them invalid which is picked up by the client which then looks unprofessional, very slow since last update, all these issues raised with customer support and still nothing done.
