LoopedTuneTrends
What is actually happening
Nights with lows. Corrections that overshoot. Meals that never come down. A block of the afternoon that sits high every day. Each one with the days that prove it.
Analyze Nightscout Trends with Trust
LoopedTune reads a few weeks of glucose, insulin and treatment data from your Nightscout site and reports the two or three patterns that matter most. Each comes with the data that prove it, the setting it points to and one thing to try this week. First run free.
About
A second pair of eyes on data you already have.
If you loop, your Nightscout site holds thousands of glucose readings, every bolus and every meal you logged. The patterns are in there — but they're spread across weeks, and nobody can hold two weeks of nights in their head at once. LoopedTune reads that history and reports the two or three things that matter most, with the actual days that prove each one.
What it will not do
It never gives you a number to put into your pump. It says higher, lower, or keep, per setting and per time of day, with the reason and the caveat — the kind of thing you bring to your care team, not a prescription. LoopedTune is not a medical device and is not approved by any regulator.
Your data
Read-only, always. It never asks for your API secret, only a token with the readable role, which it uses for one request and never stores — unless you switch on weekly runs, in which case it is kept encrypted, for that alone. Your raw glucose history is never kept; only the results of a run, on your own account.
Why it exists
Tools that make your own data legible to you shouldn't depend on one person's spare time. LoopedTune is built to last: open code, plain rules you can read, and every note traceable to the days that produced it.
How it works
Every note comes with the nights that prove it.
Not “you might be going low overnight”. Five nights, which ones, what was on board when it happened, and what to look at first.
Therapy
Which setting, which direction — and what to try
Basal, ISF, carb ratio, target: more, less, or leave alone, per time of day, with the reason and the caveat. Plus practical steps for the week that don't touch a setting.
Profile
Your profile, line by line
Every basal, ISF, carb-ratio and target block as it is in Nightscout, each marked Higher, Lower or Keep with a confidence score. Direction only — never a new number.
How it decides what to say
Every note has to survive a numeric check before you see it. Fixed rules catch the known patterns — overnight drift only counts nights with nothing on board after 20:00 and needs at least five of them; a spike that's gone by four hours is called a timing problem, not a ratio problem. Then a model scans the whole period for anything the rules didn't cover and proposes candidates — each one recomputed from your data and dropped if it doesn't hold. Lows always come first. If nothing crosses a threshold, it says so.
The token question
LoopedTune only reads, so it only accepts a token with the readable role — never your API secret, which can edit and delete your data. Make one in Nightscout under Admin tools → Subjects, paste it, done. If your site already has AUTH_DEFAULT_ROLES=readable, leave the box empty.

Two models, one run
TELOS reads the window you give it (7–30 days) and speaks: trends, therapy signals, profile verdicts, the days behind each. Any plan, any time. Aeon (Pro and Max) remembers your earlier runs on the same site — whether you changed what it advised and whether time in range moved — and then converges, holds, or reverses. Small steps, at most two changes at a time. It needs three runs about five days apart to start, and switching it on starts those runs for you. Your dashboard keeps the last 3 runs on Basic, 10 on Pro, 25 on Max.
Automatic runs
Max can repeat any run weekly. Aeon runs every five days on Pro and Max — free on Max, half a run each on Pro, so fifteen runs is about five months of tuning. Either way LoopedTune keeps the site address and, if the site is private, its readable token — encrypted, used only for your own runs, and deleted the moment you turn them off or your plan ends. You're warned before Pro credits run out.
Contact us
Bugs, wrong answers, and ideas are all welcome — especially wrong answers.
If a note looks wrong
The most useful thing you can send. Tell us what it said, what you know to be true instead, and roughly when the period was. Thresholds get tuned from real cases — one “this flagged my Tuesdays but that was a sensor problem” is worth more than a hundred clean runs.
If something is broken
Include what you pasted (the site address is fine — never send your token or API secret), what you saw on screen, and roughly what time it happened.
Medical questions
We can't answer those, and wouldn't be the right people to. Anything about your settings or your treatment belongs with your diabetes team, who can see your whole picture.
