High potential

Five stars because best in market with non intruding ads, sleek design and good performance.
Fifth star is really deserved when save city and saved cities report is available. But please keep the ads minimalistic. Dont do like the rest with those ugly ads.

Update: Downgraded to 3 stars after app failed to update for 10 hours.
Please fix this, you have a lot of potential.
