Don’t feel obligated to stick with an app just because of how long you’ve been using it. You’re not married to it and have no obligation to continue using it.
Your circumstances and requirements from an app change over time and this means there will come a point where there is probably something else that is better to use.
Occasionally it’s worth looking at all the apps you’re using and determining whether you’re still getting value out of them or just using them because that’s what you’re use to.
Are you still using all the features?
Is it doing things that way you want them to be done?
Is it saving you time?
Is it making you productive?
Is the pricing reasonable and justified for how you use it?
