A calm, private log
for methylene blue.

MB Dose Log is a simple iPhone journal: record entries, convert drops to an mg estimate from the numbers you enter, and note how your day went. Everything stays on your device.

Log entries

Record date, time, drops, and concentration in a few taps. Your history is easy to scroll and review.

Drops to mg estimate

Simple arithmetic on what you enter (assumes 20 drops per mL). A record-keeping aid, not a measurement and not a recommendation.

Daily check-ins

Note energy, focus, and mood alongside your log so your journal is all in one place.

Interaction reminders

During setup the app flags known interaction cautions (SSRI, SNRI, MAOI medications and G6PD deficiency) and reminds you to talk to a clinician.

Private by design

No account. Your entries and check-ins are stored only on your device. Purchases are handled by Apple and RevenueCat; your log is never sent to them. Read the privacy policy.
