A neon-lab tracker that knows which supplements break your fast — and which don't. Watch a live fasting ring, check off doses, and stay fast-safe.
A fasting app tells you the time. A pill organizer tells you the dose. Neither tells you that the fish oil you just swallowed at hour 14 quietly ended your fast — or that your multivitamin and your standalone D3 are stacking to nearly double the reference amount.
Supplement Grid catches all three the moment they happen — one screen, one source of truth.
The ring is anchored to a real start time, not a running process. Close the app, reboot your phone, come back a day later — it advances exactly as it should, and colors shift through the metabolic ramp as you go.
Check off doses against your fasting window. Fast-safe items tick green; anything with calories that would break your fast is flagged in warn-orange before you swallow it.
Supplement Grid knows the common absorption clashes — calcium against iron, zinc against copper — and spots the same nutrient hiding in two different products. It nudges you to space doses out or drop a duplicate, so your stack actually works together.
Compete for uptake — space them 2h apart.
High zinc long-term can lower copper.
Polyphenols cut non-heme iron uptake.
D3 also in your multivitamin — totals stack.
Every dose you log rolls into a daily total for 13 tracked nutrients. Bars fill toward the reference amount, and anything crossing the safe upper limit turns orange so you can dial it back.
Reference amounts are general nutrition guides, not personalized targets.
Supplement Grid counts down every pill as you log it, predicts your run-out date from your real dosing pattern, and reminds you to reorder while there's still time to get it delivered.
Pin the ring to your home screen and see your stage, time and next dose without opening anything.
Fasting completion and dose adherence plot out over weeks, with streaks that make the good days add up. See where you slip and where you shine — no judgment, just the data.
No account, no cloud, no tracking. Every dose, fast and nutrient total is stored locally on your device. What you take is nobody's business but yours.
The fasting timer and a couple of supplements are free. Pro unlocks unlimited supplements, interactions, nutrient roll-ups and the widget.
Supplement Grid is a general reference and tracker. It does not diagnose, treat, or prevent any condition, and the fast-safe tags, interaction notes and reference amounts are educational guides only. Always talk to a qualified healthcare professional about your supplements, fasting and any medications before making changes.
