Track If Your Medication Is Actually Working
Your doctor prescribed it. But is it helping? Track your symptoms, mood, energy, and side effects alongside your medication — and bring real data to your next appointment instead of "I think I feel a little better?"
Your Doctor Asks "How Are You Feeling?" — And You Guess
When a psychiatrist prescribes an SSRI, they tell you to check back in 6-8 weeks. When a doctor prescribes blood pressure medication, they rely on occasional office visits. The patient's subjective memory of how they've felt over weeks is unreliable.
Studies show patients recall their symptoms inaccurately — particularly for mood, pain, and energy levels. You forget the bad days. You overweight the recent days. You can't remember if week 3 was better than week 1.
This isn't your fault — it's how human memory works. Psychological research on recall bias consistently shows that people are poor judges of their own historical emotional states. A 2015 study in JAMA Psychiatry found that patients with depression systematically overestimate their current mood compared to their actual ratings from earlier in the week. When you're asked in week 8 "How did you feel in weeks 1-2?", your brain doesn't retrieve accurate data. Instead, it constructs a narrative based on how you feel right now, recent standout events, and general patterns you think exist.
Your doctor knows this. They ask "How have you been feeling?" not because they expect a perfectly accurate answer, but because it's the only data they have. They can't watch you for 6 weeks. They rely on your memory.
The solution is daily tracking. Not obsessive journaling. Just 30 seconds a day: What's your mood today? Your energy? Any side effects? Over weeks, the pattern becomes undeniable. You see the exact week your sleep improved. You notice that increased nausea on days 4-6, then it faded. You quantify the effect instead of guessing.

Medications People Track With ReactLog
ReactLog adapts to your unique health journey. Track any medication:
Antidepressants (SSRIs, SNRIs)
Track mood, anxiety, sleep quality, and side effects over the critical 6-8 week adjustment period. Many people need to find the right dose or medication — ReactLog shows whether changes are actually helping.
Anti-Anxiety Medications
Track anxiety levels, panic attack frequency, and sleep quality. Know exactly how often you're reaching for medication, whether the dose is sufficient, and any tolerance buildup over time.
Blood Pressure Medications
Track energy levels, dizziness, headaches, and other symptoms alongside your blood pressure readings and medication timing. Catch side effects early and show your doctor objective data.
Thyroid Medications
Track fatigue, brain fog, mood, weight changes, and temperature regulation. Thyroid adjustments take 6-8 weeks to take effect — daily tracking shows when you've finally hit the right dose.
ADHD Medications
Track focus quality, productivity, appetite changes, and sleep disruption. Log which time of day you feel most focused. Identify if medication effectiveness diminishes as the day goes on.
Pain Medications
Track pain levels throughout the day, mobility improvements, and side effects. Know exactly how long medication takes to work and when it wears off. Identify patterns in your pain triggers.
Any New Medication
Started something new? Track whatever outcomes matter to you. Custom tracking lets you measure the effects that matter most to your condition and your life.
Your Medication Data Is Nobody's Business
Why privacy matters for medication tracking.
Why this matters specifically for medication tracking: Medication data reveals some of the most sensitive information about you. Your prescriptions can expose mental health conditions, chronic illness, reproductive health choices, addiction recovery, sexual dysfunction — all among the most stigmatized and sensitive health data that exists.
Insurance companies would love access to your medication history to adjust your premiums. Employers could discriminate based on your mental health medications. Data brokers sell prescription data to pharmaceutical companies running targeted ads. This has happened. It's happening now.
Most health apps solve this by promising privacy. They build sophisticated encryption. They undergo security audits. They pinky-promise not to sell your data. But they still have your data. Your information lives on their servers. There's always a risk — a breach, a business pivot, a change in privacy policy, a government subpoena.
- No backend servers — Your data lives on your device only. Period.
- No analytics SDKs — We don't send telemetry about your usage patterns.
- No data collection — We have nothing to collect. No servers means no data pipeline.
- No account required — You don't need to create a login. No username, no email, nothing that identifies you.
- Face ID/Touch ID lock — Your medication data is biometrically protected on your phone.
We'd rather build a great product than sell your prescriptions to data brokers. That's why ReactLog is built to be used entirely on your device. Your medication data, your symptoms, your side effects — all of it stays on your phone. Period.
Frequently Asked Questions
How do I track if my medication is working?
Log your medication daily and alongside it, rate the outcomes you care about — mood, energy, specific symptoms, side effects, or sleep quality. ReactLog tracks these alongside your medication timing. After 2-4 weeks, patterns emerge and you can see clear correlations. If your mood has been steadily improving since you started the medication, you'll see it in the data. If your energy only improved in weeks 3-6, you'll see exactly when the change happened. This is the data your doctor needs to make good decisions about your treatment.
Can I track medication side effects?
Yes. Create custom tracking entries for any side effect you experience — nausea, fatigue, appetite changes, dizziness, sexual dysfunction, tremors, weight gain, mood swings, or anything else. Track the severity and frequency. You'll be able to see whether side effects decrease over time (as your body adjusts) or worsen (which might indicate you need a dose adjustment). This information is incredibly valuable when discussing side effect management with your doctor.
Should I show this data to my doctor?
Many patients find it extremely helpful. Your doctor is making treatment decisions based on limited information — typically a 15-minute conversation once every few weeks or months. Objective daily tracking data gives your doctor much better information than your memory of how you've felt. You can export charts and trends from ReactLog to show your doctor exactly what you've experienced. Some doctors find this invaluable; others may be less familiar with patient-tracked data. Either way, you're bringing better information to the conversation than you would otherwise.
Is my medication data completely private?
Completely. ReactLog has no backend servers and uses zero data collection. Your medication data, symptoms, and side effect tracking never leave your iPhone. Not encrypted and sent to the cloud — never sent anywhere. Your phone is the only place this data exists. We can't access it. Apple can't access it. Your internet service provider can't see it. This is a more absolute privacy guarantee than typical health apps can offer.
Is ReactLog free?
ReactLog is free during Early Access with no account required. You download the app, start tracking, and all features are immediately available. No subscription hidden behind a paywall. No "freemium" model where tracking more than 3 medications requires payment. We believe medication tracking should be accessible to everyone, regardless of ability to pay.
