# HELOSAT vs TS

The clearest difference is update cadence: TS at fortnightly against HELOSAT's every 4 months. HELOSAT's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.4). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

HELOSAT ships an update every 4 months, TS fortnightly. The most recent releases landed on November 5, 2026 and November 8, 2026 respectively.
