I tried plenty, these I kept
. Aeroweather (the paid version with NOTAMS)
. Sat 24 (hugely better than the website)
. DG Crew
. FeiXingZhiYi HD
. FR24
The rest of the needs are covered well by the company suite. It took me a while to understand that what I NEED is as few as possible. So ditched all the others.
Especially at the beginning, I suggest to maintain an old school paper logbook. Take all the signatures and stamps in it that you can, simulators included. At least until obtaining full ATPL. You never know when you'd need those, see my app no. 4.
