how can you compare Monzos ATM daily withdrawal of £400 / day - £2000/month free with Revoluts £200 / month and then above that a 2% fee and favour Revolut above Monzo ? that would be a £36 fee to use revolut every month up to Monzos limits ( my ATM limits anyway 
others have different limits - New Limits! )
from Revolut website “-ATM withdrawals - Free up to £200 (or currency equivalent) per calendar month. A 2% fee applies thereafter”
- Monzo don’t charge for a card - your £100 top up is just that - a top up with money you are free to use straight away - the absolute opposite is true with revolut, they charge a minimum of £5 for your card + £6 for a replacement card - Monzo is totally free to send out and get a replacement for a lost card
Is the revoluts interbank rate better than MasterCard rates ? - http://www.morningstar.co.uk/uk/markets/currencies.aspx

Monzo also don’t charge any commission at weekends from Friday midnight to sunday midnight (or indeed any other time) - unlike Revolut minimum of 0.5% at weekends - how can that be better FX rates - don’t spend FX at weekends ?

just checked morning star FX rates for today GBP-US is $1.249=£1 (+ your 0.5% commission so $1.243 ) mastercard for yesterday was $1.26 = £1 maybe it changed dramatically overnight
€1.182 (+0.5% so €1.176) for morningstar FX and €1.19 for MasterCard
never used Android so couldn’t comment on your other points
