Juno vs Guava (2026): Symptom Tracking Compared
Managing chronic illness shouldn’t feel like a job. Guava is built to gather your medical records in one place. Juno is built to help you live day to day: you talk, and she logs your symptoms, helps you pace and gets you ready for appointments. Here’s how they compare, including what Guava’s own users say.
The short answer
Pick Juno if you want help with day-to-day life with chronic illness. Talk to Juno by voice or text and she logs your symptoms, medicines, mood, sleep and energy as you go. She remembers what you’ve told her, helps you plan around your energy and gets you ready for appointments. Juno is built on founder research from Oxford and UCL.[1][10][30]
Pick Guava if your main goal right now is to collect US patient-portal records, lab results and measurements in one place. That’s Guava’s biggest strength, and its users praise it for that. Health records are coming to Juno soon, and they’re being built to work internationally, not just in the US.[2][9]
Why people choose Juno
- Say it once. One sentence or a voice call can log a symptom, a dose, your mood and your sleep. No forms to fill in on a bad day.
- Real conversations, including live voice calls. Talk things through, interrupt her, or turn on your camera so she can see a rash or a pill label.
- She remembers you. Juno remembers what you’ve told her across chats and calls, and you can correct her.
- Pacing that knows how you slept. Spoon costs for your day adjust to your sleep, heart rate and how busy yesterday was.
- Built for life outside the US. 13 languages, NHS and NICE sources, and medical records coming internationally.
- Rooted in research. Juno is built on founder research from Oxford and UCL.[30]
Juno
An AI health companion you can talk to. She logs your symptoms as you chat, helps you pace and writes your appointment summaries.[1]
What Guava users say, and how Juno is different
We read Guava reviews on Google Play, the App Store, Trustpilot and Reddit. Most are positive, and Guava averages 4.6 to 4.8 stars on the app stores. The same few frustrations come up again and again, though, even in good reviews. Here’s what they are, and how Juno handles each one.[14][22][25]
“The insights don’t tell me much.”
Several Guava users say the automatic insights felt generic, told them things they already knew, or weren’t useful. Guava has replied that this feature is still improving. On the free plan, you also have to choose which two things to compare yourself.[14][22][24]
With Juno, you just ask. “Is my fatigue worse after bad nights?” Juno looks back over about a month of your symptoms, sleep, mood and energy, and talks you through what tends to happen together. You can ask follow-up questions, and once you have enough days logged, Juno suggests questions to ask.
“I have to enter so much by hand.”
This is the most common complaint. Users describe logging the same thing twice because synced data can’t be edited, typing in numbers that didn’t sync, and finding food logging overwhelming. One person said even taking food photos was too much on some days.[14][22][23][24]
With Juno, you say it once. “Bad night, took two paracetamol at 3, hands are really stiff this morning.” From that one message, Juno saves the sleep, the medicine and the symptom. Anything bigger, like changing a schedule, gets a quick card for you to approve first. You can also bring your history over from Bearable, Visible, CareClinic or a spreadsheet.
“It’s hard to find things.”
Reviewers say useful features, especially exporting, took a while to find. Some say setup took effort, and older Reddit comments describe the home screen as overwhelming until it was customised.[15][22][25][26]
With Juno, the conversation is the menu. Ask “Make me a report for my GP” or “Remind me to call the pharmacy at 4” and Juno does it, so you don’t have to hunt through screens.
“It’s built for the US.”
Guava’s own guide says it mainly connects to US patient portals. A UK reviewer said the app had gaps because it was geared towards the USA.[5][14]
Juno is built to work wherever you live. It’s available in 13 languages, uses NHS and NICE guidance, and includes UK food data. Medical records are coming to Juno soon, built to work internationally.
What Guava users like
To be fair, Guava users consistently praise it for bringing portal records, labs and wearables together in one place. They also like its generous free plan with no ads, a team that responds quickly, and Visit Prep summaries for doctors. Some say its correlations helped them find real triggers.[14][22][23][25]
Side by side
Both apps let you log symptoms, look back at changes and prepare for appointments. With Juno, you start with a conversation. With Guava, you start with a record of information from different places.[1][2]
| What matters to you | Juno | Guava |
|---|---|---|
| Logging without forms | One message or voice call can log symptoms, medicines, mood, sleep, food and energy. | Form-based logging, plus an AI Assistant for voice and text on Premium.[4][5][6] |
| Live voice calls | Talk to Juno in real time, with the camera on if you like. She logs as you talk. | The Assistant accepts spoken updates.[5] |
| Pacing and planning your energy | A daily spoon budget, activity costs that adjust to your sleep and heart rate, and a “plan my day” chat.[19] | Logs activities and finds symptom links. Its guides don’t describe spoon planning.[18] |
| Understanding your patterns | Ask in plain words. Juno looks across your recent logs and talks you through them. | Run correlations yourself for free. Premium searches for them automatically.[7] |
| Bringing in your medical records | Coming soon, built to work internationally. | Syncs with supported US patient portals. Elsewhere, you upload files by hand.[2][5] |
| Using it outside the US | 13 languages, NHS and NICE sources, and UK food data. | Works worldwide, but record syncing is mainly for US portals.[5][9] |
| Support on bad days | Emotional support in the same chat, plus flare relief ideas linked to NHS and NICE guidance.[10] | An assistant for logging, searching and analysing your health data.[5] |
| Reading your documents | Send a photo or PDF of a letter or lab result and ask what it means. | Upload documents and Guava pulls out the data. The free plan auto-extracts a limited number.[2][28] |
| Sharing a summary before an appointment | A doctor report PDF with charts and a short summary, or a doctor letter.[1] | Build, download, send or print a Visit Prep summary.[8] |
| Wearables | Apple Health, Health Connect, Samsung Health, Oura, Garmin, Fitbit and Withings.[1] | Apple Health, Health Connect, Oura, Fitbit and more.[5] |
| Peer community | A moderated community feed, groups and direct messages with other people living with chronic illness. | Not described in the Guava guides we reviewed. |
| Sharing with your doctor | Email your report straight to your doctor from the app, or share it as a PDF.[1] | Share your profile, or give access through Guava’s Provider Dashboard if your provider uses it.[9] |

Logging your day
Juno: just say what happened
Talk or type to Juno like you would to a friend. She picks out the symptoms, how bad they were, when they happened and anything you took, then saves them for you. You can also log by hand, use home-screen widgets, or snap a photo of handwritten notes.[1][3]
Guava: forms or its AI assistant
Guava has symptom forms with time, severity, body location, notes and photos. Its Assistant also takes voice and text on the Premium plan.[4][5][6]
Pacing for ME/CFS and Long COVID
If you have ME/CFS, or Long COVID with post-exertional malaise (PEM), you might feel fine while you’re doing something and pay for it a day or two later. NICE guidance says managing energy should be flexible and based on your own limits, which change over time.[20]
Juno helps you work out what a day will cost before you commit to it. Rate your energy and Juno gives you a spoon budget for the day. Each activity gets a spoon cost that counts physical, mental and emotional effort. Ask Juno to “plan my day” and she’ll help you shorten, move or drop things and leave time to recover. She can even estimate costs for the events in your calendar.[19]
Your costs change with your body. If you’ve slept badly, or your wearable shows a raised resting heart rate or low HRV compared with your own normal, activities cost more. After a very busy day, Juno suggests a lower energy level for the next day, because PEM often hits 12 to 48 hours later.
Take an appointment. It isn’t just the appointment. It’s getting ready, travelling, waiting, concentrating and getting home again. Seeing all of that together might help you decide to ask for a lift or keep the afternoon free.[19]
Guava’s guides show you how to log activities and look for links with your symptoms, but they don’t describe spoon planning. One person with ME/CFS on Reddit said they use Guava for detailed tracking and a separate app for pacing. With Juno, it’s all in one place.[18][27]
Spoon estimates are a guide, not a guarantee. They can’t tell you what’s medically safe or promise that pacing will prevent a crash.
Finding patterns
To use Guava’s correlations, you log your symptoms and the things that might affect them, ideally for about 30 days. On the free plan, you then choose a symptom and a possible cause, and Guava tells you how closely they’re linked. Premium searches for links automatically.[18][7]
Users who already suspect a trigger find this useful. Others say the hard part is knowing what to test when you don’t have a hunch yet, or that an average energy score hides their highs and lows.[14]
With Juno, you ask the question you actually have. “Why have I been so wiped out this week?” Juno looks back over your symptoms, sleep, mood, energy and medicines, and talks you through what tends to happen together, and when. Then she helps you turn that into a plan, like an easier day tomorrow.[1][19]
As with any tracker, a pattern isn’t proof that one thing causes another. Take anything important to your doctor.
Feeling heard
A complete medical record isn’t the only reason to open a health app. Sometimes you want to talk about how a flare has wrecked your day, say that you feel alone, or think a worry through before it becomes a note.
This is one of the main reasons people choose Juno. You get emotional support and symptom tracking in the same conversation, by voice or text. Juno listens without judgement, understands fatigue, pacing and invisible illness, and remembers what matters to you over time.[10]
On a bad day, Juno Relief suggests a few things to try, each linked to NHS or NICE guidance, and there are guided breathing and quick mood check-ins. You can also join Juno’s community to talk with other people who get it.
Juno users say the same in public reviews: one valued how understanding the replies were, and another said it felt like talking to a friend who knows their stuff.[16]
Living outside the US
Guava’s automatic record connections are mostly for US patient portals. Guava’s own guide says so. If you live elsewhere, it tells you to upload records by hand, which can mean requesting files, scanning letters and uploading them yourself.[2][5]
Juno is built for everywhere. Its everyday features don’t need a patient portal. It’s available in 13 languages, uses NHS and NICE guidance and includes UK food data.
Medical records are coming to Juno. We’re adding the ability to bring your health records into Juno soon. Unlike Guava’s US-focused connections, it’s being built to work internationally, so it’s useful wherever you’re treated.
You can email your Juno report straight to your doctor from the app, or share it as a PDF or doctor letter. Guava also has a Provider Dashboard for clinicians who use it.[1][9]
Getting ready for appointments
With Juno, what you say today becomes the history you share later. When an appointment is coming up, Juno turns your logs into a doctor report with a short summary, charts, and tables of your symptoms, medicines and triggers.[1][17]
- Say it: “Please log yesterday’s headache. It started after lunch and I had to lie down.”
- Check it: make sure the symptom, date and severity are right.
- Send it: ask Juno for a report, add your questions, and email it straight to your doctor.
See our example report to see what it looks like.[1]
Guava’s Visit Prep also turns your symptoms, medicines and records into a summary you can share, and users rate it highly.[8][22]
Pricing
You can try both for free. Juno’s tracking, pacing, health insights, doctor reports and community are included in its free plan. Juno Pro adds unlimited AI chat and enhanced memory. Compare the current regional prices and features in each app before choosing.[1][6]
Privacy
We don’t sell your health data. Your data is encrypted when it’s sent and when it’s stored, and our agreements with AI providers stop them training their models on your health data.[1][12]
Guava also says it doesn’t sell your data. Its policy covers encryption and how to download your data or delete your account, and when you share, you choose what to share and for how long.[13][9]
Which should you choose?
We recommend Juno if you want something that helps you live with chronic illness, not just record it. You talk, Juno logs. You ask, Juno explains. And when an appointment comes up, your history is ready.[1][10][17]
Juno is likely to suit you if:
- Filling in forms feels like too much on a bad day.
- You want to ask about your patterns in plain words.
- You need to pace, and want your plan to adjust to how you slept.
- You want emotional support and a community, not just charts.
- You live outside the US.
Guava is a good choice if gathering US portal records, lab results and detailed measurements comes first for you today. Health records are coming to Juno soon, built to work internationally.[2]
Not sure? Try both for free. Log one bad day in each, then ask yourself which one you’d actually open tomorrow.
