Congrat to being on the portal.
I have some idea to recommand which could be great.
-Include a reminder about oil filter, windshield replacement based on the distance.
-Include a reminder about tire replacement based on the distance or law about season (in my province in canada, we need to replace the summer tire for winter tire before the 15th of november they are required all the winter to the 15th of april, i live in Québec province in Canada),
-Include a reminder about refilling Oil, Prestone, Windshield washer, gaz (this one seem really stupid. XD).
-For electric car, reminder when you enter your drive way to recharge it.
I will recommand this app, GJ !
