# DigiCompCalc vs FlashMob

The clearest difference is rating: DigiCompCalc at 5.0 against FlashMob's 4.4. DigiCompCalc also leads on in-app purchases (none vs 3) and ads (none vs shown). FlashMob's advantage is update cadence (every 2 months vs every 68 months) and ratings volume (174 vs 2). On price, device support and iOS requirement there is nothing between them.

Both are free to download. FlashMob sells 3 one-off in-app purchases. DigiCompCalc asks for nothing beyond the download.

DigiCompCalc holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: FlashMob has 174 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of DigiCompCalc's written reviews are positive against 81% of FlashMob's.
