The short answer

Yes, in two forms. Programmes with a human coach, such as Second Nature and Oviva, pair an app with a dietitian or health coach, and in the UK you usually reach them through an NHS referral. Bolus has the coach built in: Emily knows your meals, activity, weight and, if you connect one, your glucose, and you can message her any hour without an appointment. She is the app itself answering, not a person on shift, and she does not give medical advice.

Two different things called a coach

If you have been referred to a programme with a real dietitian behind the chat, and you later open an app with a coach built in, it is reasonable to assume the same thing is on the other end. It isn't, and any honest app should say so at the first mention. The useful question is not which is better in the abstract but what you need the coach to do.

  • A human coach can take a history, individualise advice, and is accountable as a professional. They are also on shift: you get a slot, a reply within a day or so, and a programme that ends.
  • A coach built into the app is there at 6pm on a Tuesday, knows exactly what you ate this week because it planned it, and keeps going for as long as you use it. It cannot give medical advice and should direct clinical questions back to your team.

For a lot of people with type 2 or prediabetes the gap is not advice. They have had the advice. The gap is the weekday evening when the plan meets real life, and that is where an always-on coach earns its place.

What Emily does in Bolus

Bolus plans a week of meals around how you like to eat, from a nutrition framework developed by a specialist diabetes dietitian who previously worked in NHS diabetes services, brings in your activity from Apple Health, and keeps a weight goal alongside. Emily sits on top of all of that. Ask her about your food, activity, weight or glucose and she answers from the information Bolus already has, rather than from a generic script.

  • Goals agreed together. Across food, exercise, weight and other areas of health, with a next step that fits the week you actually have.
  • Follow-up. She checks in on how it went, and helps you adapt rather than start again.
  • A weekly review. What worked, what got in the way, and what to focus on next.
  • A summary for your appointment. Recent food, activity, weight and glucose, in a form you can take to your diabetes team.

The coaching is grounded in behaviour science and designed to turn intentions into realistic actions, not to hand you more information. Emily does not give medical advice, does not touch insulin or medication, and is not a dietitian, doctor or diabetes educator. Emily is part of Bolus Premium; the weekly food plan is free.

Questions to ask any coaching app

  • Is the coach a person or the app? Either can be right. Not being told is not.
  • What does the coach know about me? A coach that can see your actual meals and activity gives different answers from one working off a questionnaire.
  • When can I reach them? Office hours and a waiting list, or any hour.
  • What happens when the programme ends? Twelve weeks of coaching is useful. Week thirteen is where most people are on their own again.
  • Where is the line on medical advice? Any coach, human or app, should send questions about medication, insulin or glucose targets to your diabetes team.

The human-coach programmes

  • Second Nature pairs its app with a human coach who is a registered nutritionist or dietitian, available Monday to Friday with replies aimed within 48 hours, plus a peer group. Free by NHS referral where commissioned (it delivers parts of the NHS Diabetes Prevention and Digital Weight Management programmes), or self-pay from about £28 to £38 a month after a trial. No calorie counting.
  • Oviva is NHS-funded only, reached by GP referral or self-referral in listed areas, with dietitians and clinicians coaching through the app or by phone, a photo food diary, and a regulated medical device status. Its type 2 programmes exclude type 1.
  • Noom offers optional one-to-one coaching on top of a calorie-budget tracker, plus an AI assistant for routine questions. General weight loss rather than diabetes.
  • SNAQ has an AI nutritionist and no human coach, built on photo logging of meals.

A coach who already knows what's for dinner

Bolus plans the week around how you like to eat, brings in your activity, and keeps your weight goal alongside. Emily, the healthy eating coach built into the app, helps turn it into realistic next steps and follows up, any hour, with no appointment. The weekly plan is free; Emily is part of Bolus Premium.

Frequently asked questions

Is Emily a real person?
No. Emily is the coach built into Bolus: the app itself answering, not a person on shift. She answers from your own food, activity, weight and glucose, any hour, and does not give medical advice.
Is a human coach better than a coach built into an app?
They do different jobs. A human dietitian or coach can individualise advice and is accountable as a professional, but works to appointments and a programme that ends. A coach built into the app is always available and knows your week in detail, but cannot give medical advice. Many people use both at different stages.
Can Emily give me medical advice?
No. Emily stays within food, activity, weight and everyday life with diabetes. Questions about medication, insulin or glucose targets go to your diabetes team, and she will say so.
Is Emily free?
Emily is part of Bolus Premium, paid monthly or yearly through Apple with the price shown before you subscribe. The weekly food plan, shopping, swaps and weekly review are free and do not expire.
How do I get a human coach through the NHS?
Ask your GP practice. Programmes such as the Healthier You NHS Diabetes Prevention Programme, and in some areas Oviva or Second Nature, are available by referral depending on where you live and your diagnosis.
Does Bolus work alongside a human-coach programme?
Yes. Bolus gives general food, exercise and weight support and is not a medical device. If your programme or dietitian has given you a specific plan, follow theirs, and check with them before running the two together.
