Federal bank got their own apps just search for them and you will get it, as for these other two they can be there without any issue cause they aren't owned by federal bank, federal bank is just a banking partner to them powering their accounts and cards, Fi is a product of epiFi Technologies Pvt. Ltd. and Jupiter is a product of Amica Financial Technologies Pvt. Ltd. and of course both of these companies aren't subsidiaries of Federal Bank Ltd. Hope it helped, More power to you.
