Understand your energy envelope.
Pacing means matching demand to what you can tolerate. Elara brings exertion, energy, recovery, and symptoms together so you can review your personal pattern over time.
Higher demand – physical, cognitive, or emotional exertion
Delayed worsening – a pattern that can occur with PEM
More manageable range – observed over time, not a guaranteed safe zone

“Benutze es jetzt die zweite Woche und bis jetzt sehr begeistert und hilfreich. Man muss aber die App erst einmal füttern., um Crash grenzen zu erkennen, bin gespannt, wie das in ein paar Wochen später aussieht! Aber bis jetzt alles super danke für eure Mühe. Es ist eine echte Unterstützung für den Alltag für uns mit CFS”

“Einfach.Übersichtlich.Hilfreich. Eine App die alles beinhaltet. Medikamentenerinnerungen,Ernährung Mediationen, Symptome eintragen,bewerten.Schlaf ,Stimmung alles wird zusammen erfasst und ausgewertet. Ich tracke mit der Appel Watch. Kann mittlerweile mein Energielevel besser einschätzen. Seit Februar dabei und kann die Berichte auch per pdf ausdrucken für meine Ärzte und Behörden. Es gibt eine WhatsApp Gruppe mit der man sich austauschen kann. Nicht aufgeben wenn es mal hakt, es erschließt sich nach und nach. Man muss dranbleiben.DANKE an Frederik und Team für die tolle Unterstützung. Bin nach jedem Update begeistert und denke besser geht es nicht. Und ihr zaubert immer wieder noch Vereinfachungen dazu.”
