You have tracked carefully for months and still cannot see a pattern. That is not a discipline problem. Logging is the part people do well. Analysing months of entries is the hard part, and almost nothing helps with it.
You have probably done the hard, boring part already. People with a long-term condition tend to track more carefully than anyone else, often for years.
But logging and analysing are two jobs, and the second is genuinely difficult. Three months across a dozen factors is about a thousand data points. Causes often sit two or three days upstream. Sleep, stress and weather rise and fall together. No one finds a clean signal in that by eye.
None of this is about how well you kept the record.
Storing what you type is easy to build. Comparing it properly is not, so most tools stop at storage and hand you a chart.
A chart is not an analysis. It shows what you already typed, arranged prettily. It will not tell you the pattern appears just as often on your calm days, and it will not check three days back.
There is a second failure, and it is a choice rather than a limit. Many tools treat a missed day as a lapse and reset your progress. The days people miss are usually their worst.
Moya is built for the second job.
The review puts your days side by side, calm ones included. When it compares two things it uses every day you logged, not just flare days, because a factor that appears just as often when you are fine is not telling you much. When there is not enough on record, it says so and tells you how many more days it needs.
The check-in takes under a minute, because the record only stays comparable if it keeps going. The streak survives a bad week: today counts as pending rather than missed, and one missed day in a week is absorbed, so the app tells you your rest day was used and your streak is safe.
What it will not do is decide what is causing your flares. It can show what tended to appear alongside what. No software can tell you something is a trigger, and anything phrased as a conclusion rather than an observation should make you suspicious of the tool.
Your check-ins are stored on your device, not on our servers. A few features do ask a server a question to work, identifying a food from a photo being the obvious one.
Because the comparison is hard, not because your record is poor. Three months of entries is around a thousand data points, causes can sit days before a flare, and everyday factors move together. Picking one out by eye is not a reasonable thing to ask of yourself.
Count flares, not weeks. Around five or six separate flares is where a pattern becomes worth trusting, usually six to eight weeks. More in [how long to track before a pattern means anything](/guides/how-long-to-track-before-a-pattern-means-anything).
Usually the opposite. More columns make the review harder and give coincidences more chances to line up.
An unbroken flare gives a diary little to work with, because nothing varies enough to stand out. Logging whether today is better, the same or worse than yesterday keeps some contrast. What changed in the weeks before the run began is often more useful than anything inside it.
No, and be wary of one that says it can. Software can show what tended to appear alongside what. Whether it is causing your flares is a clinical question.
Worth it if they do the comparing. An app that only stores what you type has handed the hard half back to you.
Yes, several, including Moya, which covers eczema, psoriasis, rosacea and seborrhoeic dermatitis. Check what an app does with your entries after you make them.
Yes, and that is a finding rather than a failure. Plenty of flares have no outside trigger. Knowing it stops you cutting out foods and products for nothing.
