I'm a new user and haven't tried the whole concept but here a more a few things that would help PTs and their clients:
1, myzone integration: helps to keep client's accountable and motivates to higher effort and therefore better results
2, weekly breakdown of crucial lifestyle elements: daily regime = food timetable, alcohol, stress levels
3, hip to waist ratio: as a part of more accurate health risk measurement. Better than BMI in my humble opinion.

I would have a weekly check in form for clients

Check-in questions so you didn't have to leave the app to do check-ins. Customisable question boxes and scheduling to client's calendars on different days

Ability to send check-in forms/survey/questionnaire each week so clients can fill them out with various fields like tracking energy, mood etc.

Sending weekly check in survey/forms clients have to fill in

The ability to have a client do a daily or weekly check in would be amazing to get a feel for energy, mood, alcohol consumption, etc. Would be great to see this info then populate into graph form when appropriate (hours of sleep, for example).

There could be a “Check-in” tab within each clients account and then it saves once submitted. This would then keep all check-ins in structured order.

It would be great if us Coaches were able to personalise check-in forms within the app and then send the form directly to all of our clients that need to fill it in.

I am currently having to do my weekly check-ins elsewhere, which makes my job a lot longer than it should be as I have to keep switching back to the app to view client data.

I also have some clients who find it stressful having information spread about rather than keeping it all in one place, as they lead busy lives and need as much simplicity as possible. Thank you,

I am currently having to do my check-ins elsewhere which means I have to keep switching back over to Trainerize to view client data.

It would be great if we could
Personalise our check-in form and be able to send it straight to our clients account for them to fill in and submit. I know TrueCoach have something like this.

I constantly forget to send my check-ins to my coach. Add a reminder for that.

The check in form should be native to Trainerize so your client doesn't have to leave the app

Yes! Brad said it great :

Ability to set a check in form, much like a body stat or check in photo in calendar. That we can set and code ourselves, much like the original consult form.

PYHub and PT distinction offer great form support. Hoping you will soon too.

Right now my clients have to email me or fill out a form outside the trainerize app. It would be nice if there was a check-in section / form directly on the app to use. As well as add check-in dates to their calendar!

Yes, please!!!

Be able to create customised forms to send daily

An area to customize check in questions on top of physical progress stats for your clients i,e.
Did you feel motivated this week?
How was sleep/ stress?
How was mobility?
What was something you were proud of?
Something you want to focus on improving next week? etc

Please!!

This is a great idea. I see other programs like PT or Total Coaching has the ability to send customized forms from in the app. Trainerize should be able to do this too

it would be great to be able to have a check-in form where the trainer could create their own questions (similar to Google Forms) that could be scheduled into the client's calendar to be sent out as scheduled by the trainer. It would be really great to also have the the ability for the trainer to respond to the the client's responses to the Form questions, and the client to then be able to respond back again. This way the trainer could continue multiple discussions around all check-in topics.
