- Noom is a psychology-based weight-loss program with daily lessons, coaching, and calorie tracking. It costs $17-70/month depending on plan length.
- MyWhy is a free behavioral companion app for GLP-1 users — meal check-ins, treatment tracking, and daily reflections with no calorie counting.
- Noom's GLP-1 support (Noom Med) costs $199/month and includes prescriptions. MyWhy offers free GLP-1 tracking for people who already have a prescription.
- Both apps take a behavioral approach. Noom uses structured lessons and coaching. MyWhy uses self-directed awareness tools.
- If you want guided coaching and can invest $17-70/month, Noom delivers. If you want free GLP-1 tracking with behavioral tools, MyWhy is built for that.
MyWhy and Noom both believe that weight loss is a behavior change problem — not just a calorie math problem. That's where the similarity ends. Noom is a comprehensive coaching program with daily psychology-based lessons, a color-coded food system, group accountability, and a personal coach. MyWhy is a lightweight companion app with photo-based meal check-ins, GLP-1 treatment tracking, and daily reflections — all free.
They're built for different situations, different budgets, and different stages of the weight-loss journey.
Pricing: The Elephant in the Room
Noom Weight
$17.42/mo on annual plan
14-day trial available
MyWhy
MyWhy+ optional at $9.99/mo
No trial needed — it's free
Noom's pricing is commitment-based: the annual plan ($209/year) is the best value, but you're locked in. The monthly plan at $70 is steep for an app-based program. And if you want GLP-1 medication support through Noom Med, that's a separate $199/month that includes the prescription itself.
MyWhy's core features — meal check-ins, GLP-1 treatment tracking, drug-level visualization, weight tracking, daily reflections — are all free. The optional MyWhy+ tier ($9.99/month) adds guided journey content and advanced reflection prompts, but it's not required for the main experience.
Over 12 months, that's a difference of $209-840 (Noom) vs. $0 (MyWhy).

The Philosophical Difference
Both MyWhy and Noom use behavioral psychology — but they apply it differently.
Noom is a teacher. It delivers daily lessons on topics like emotional eating, portion control, cognitive distortions around food, and the psychology of habit formation. You read a lesson (5-10 minutes), answer quiz questions, and discuss with your coaching group. It's structured, sequential, and content-heavy. The lessons are genuinely well-written and based on real psychology research.
MyWhy is a mirror. It doesn't teach you about behavioral psychology — it gives you tools to practice it. The photo-based meal check-in is a self-monitoring exercise. The daily reflection is metacognitive practice. The weekly meal pattern view is pattern recognition. The "Why" feature is motivation anchoring. You learn by doing, not by reading.
Neither approach is inherently better. Some people thrive with structured education and coaching. Others do better with simple, self-directed tools they can use on their own terms. The question is which resonates with how you learn and change.
Who Should Choose Noom?
Noom
$17-70/mo (Weight) · $199/mo (Med)Noom is a good fit if you want a structured, guided weight-loss program with daily lessons, coaching support, and a comprehensive approach to behavior change. It's like having a weight-loss course built into an app.
Strengths
- Psychology-based daily lessons (genuinely well-made)
- Personal coaching and group support
- Color-coded food system (intuitive)
- Noom Med option includes GLP-1 prescriptions
- Large community with accountability circles
- 14-day trial lets you test before committing
Limitations
- $17-70/month is a serious commitment
- Noom Med at $199/mo is premium-priced
- Still uses calorie counting as core tracking
- No injection tracking or drug-level viz (even in Med)
- Annual plan lock-in for best pricing
- Content can feel repetitive after a few months
Best for: People who want guided coaching, structured education, and are willing to pay for a comprehensive program. Also for people who need a GLP-1 prescription and want an all-in-one solution (Noom Med).
Who Should Choose MyWhy?
MyWhy

- Full GLP-1 treatment tracking with drug-level viz
- 30-second meal check-ins (no calorie counting)
- Daily reflections and motivation anchoring
- Ad-free — even on the free tier
- Designed specifically for GLP-1 users
Limitations
- No structured educational lessons
- No personal coaching
- No community features (yet)
- No calorie or macro tracking
- Newer app with smaller user base

Best for: GLP-1 users who already have a prescription and want free treatment tracking plus behavioral weight management tools. People who prefer self-directed learning over structured lessons. Anyone who wants to save $200-840/year.
What About GLP-1 Users Specifically?
This is the critical question for a growing number of people. If you're on Ozempic, Wegovy, Mounjaro, or Zepbound, here's how the two compare:
If you need a prescription: Noom Med ($199/month) includes a clinician who can prescribe GLP-1 medication, plus the Noom Weight coaching program. MyWhy doesn't prescribe anything — you need to have your own prescription.
If you already have a prescription: MyWhy is the stronger choice. It includes the treatment tracking features that Noom lacks entirely — injection logging, drug-level visualization, dose escalation timeline, and injection site rotation. Even Noom Med, at $199/month, doesn't offer these features. MyWhy gives them to you for free.
Can you use both? Absolutely. Some people use Noom for its daily lessons and coaching while using MyWhy for GLP-1 treatment tracking. The apps serve different functions and don't conflict.

The Verdict
Noom is the best structured weight-loss coaching program in an app. Its psychology-based lessons are high quality, and the coaching adds accountability. But it costs $17-70/month, still relies on calorie counting for meal tracking, and has zero GLP-1 treatment tracking features.
MyWhy is the best free GLP-1 companion app. It gives you treatment tracking, drug-level visualization, behavioral meal check-ins, and daily reflections at no cost. It won't teach you psychology lessons or assign you a coach — but it gives you the tools to practice behavioral weight management every day.
If budget is no concern and you want maximum guidance, Noom delivers. If you want a free, focused tool that tracks your GLP-1 treatment and supports weight loss without counting calories, MyWhy was built for exactly that.
