StackLog Daily
Supplement & Vitamin Tracker
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
See what your stack adds up to, with a heads-up when a nutrient tops its NIH upper limit. Check off doses in one tap. No account; it all stays on your phone.
StackLog helps you track the supplements you already take and remember the ones you meant to take today.
Add items from the built-in list of 130+ supplements or create your own. Organize them as morning, with meals, or evening. On Today, mark Taken or Skip, or mark a whole group taken at once. The 12-week grid shows which days you logged. Supply estimates days left from quantity on hand. Optional local reminders fire on this device only.
There is no account and no cloud sync. Your daily log and history stay on the phone.
StackLog is not medical advice and is not a diagnostic or treatment tool. Nutrient totals are compared with general reference ranges from NIH, and research ranges link to their public sources; they are informational, not personal recommendations. Talk with a qualified clinician before starting, stopping, or changing any supplement.
