Verdict

The call

The clearest difference is in-app purchases: Star Map Night Sky at none against Telescope's 10. Star Map Night Sky also leads on update cadence (fortnightly vs every 5 months). Telescope's advantage is ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
